SMART Adventures: What Trials Bikes Can Teach You About Motorcycle Control

I'm still thinking over our day this past July, 2020 at SMART Adventures Off-Road Training.  This was our third year taking off-road training with this fantastic program that runs out of Horseshoe Resort just north of Barrie in Ontario, Canada.  If you're interested in expanding your bike-craft, this program will do just that, and they're open during the summer of COVID with all appropriate safety in place (masks, social distancing, temperature testing of all people prior to starting, etc).

Last year Clinton Smout, the owner and head instructor at SMART, had us all try balancing on a stationary trials bike, and that got me thinking about doing a session with them this time.  I'd watched Ross Noble take a run at the Scottish Six Days Trial on TV which was gruelling and battering to his ego and always wondered just how different trials bike are from dirt bikes, so here was my chance!

What is 90 minutes of trials riding like?  Very difficult.  Just to get going you have to give it a bit of gas and let out the clutch and then lift your foot up as you start moving.  Screw it up and you're hoping along on one foot trying to keep the bike upright as it tries to jump out from under you.  Starting to move on these bikes is harder than any other bike you're ridden, and that's just the beginning.

I was on a GasGas 250cc two stroke trials bike, and it was like trying to hang on to a wild horse (I presume, I've never tried to ride a wild horse because I'm not crazy).  It weighs about half what I do, has way too many horsepower and tries to squirt out from under you at every opportunity.  I got Clinton as an instructor this time and he made a point of highlighting just how mad these things are.  The brakes have thrown people over the handlebars and the acceleration has had people wheelie the machine on top of themselves, so if you're going to touch the gas or brakes expect it to respond way more suddenly than any other bike you've ridden.



How do you handle this madness?  The clutch!  A finger on the clutch and a finger on the front brake will reduce the arm pump you're going to experience (Clinton was right, I've gotten good at dirt bikes and can stay loose, but on this crazy thing my forearms were throbbing after an hour).  Without supreme clutch control you're going to launch yourself into the sky on a trials bike.  If you crack the throttle to make it go it'll try and throw you, if you hit the brakes too slow down it'll try and throw you.  You need to modulate the clutch to manage these inputs with any kind of finesse.

I like to think I picked this up pretty quickly.  The GasGas never threw me and I handed it back in the same condition I got it.  Like everything else I've ridden my long body meant my back was what was taking the brunt as I had to bend over the machine.  If I were ever to get my own trials bike it'd have risers or modified handlebars so I can stand straight up on it.  Were I to go after trials riding (and a part of me is very trials-curious), I'd enjoy the violent focus it puts on your control inputs the most.  Once you catch up to what the bike expects, it raises your clutch control to god-like levels.

In the afternoon I took out a Yamaha 250cc dirt bike and couldn't believe what that intensive morning on the GasGas had done to my clutch hand.  Instead of too much gear changing or braking I was modulating the clutch constantly to ride smoother than I ever had before.


It takes a trials bike to make dirt biking seem easy.

Suddenly situations that might have made me stop and adjust my gearing didn't matter.  Between clutch and throttle I could manage deep sand, mud, 30° inclines (in deep sand) and axle deep puddles without hesitation.  I couldn't believe the difference.  When we stopped my son's ATV instructor said, "ok, you know what you're doing", which was a fantastic thing to hear.

If you have access to SMART Adventures (you can get yourself to Ontario, Canada in the summer of COVID), go.  It'll improve your bike-craft even if you're a pavement focused rider.  After you've got the off-road basics down take a swing at trials riding.  It'll give you an appreciation of clutch control and drill you so aggressively in it that your left hand will come out of it with the twice the IQ it came in with.

I even notice it while riding on the road.  I was out on the Honda Fireblade the other day and noticed that my clutch hand was modulating the bike in new and interesting ways.  In mid-corner as I'm winding out power my left hand is helping the bike deliver drive smoothly without me realizing it.

I'm a strong advocate of life long learning and applying it to your bike-craft should be every motorcyclist's main purpose.  If you want to keep enjoying the thrills of riding you should be looking for ways to better understand the complexities of operating these machines.  A couple of hours working with trials bikes did that for me.  I wish I had the means to chase down an ongoing relationship with these visceral, demanding and ultimately enlightening machines.

Labour Day Weekend Ride: Georgian Bay

 A 300km round trip up to Georgian Bay and back:


I aimed to get out of the boring straight lines of South West Ontario and over to the Niagara Escarpment as quickly as I could.  I was going to head up Highway 6 but it was packed full of GTA types escaping their pandemic ridden cities, so I angled off in Fergus and took 16 up, which was completely empty.  That would become a theme of the ride.

It took me about an hour to get up to Flesherton, where I made a stop at Highland Grounds for an Americano.  I usually enjoy sitting in there sipping my coffee while sitting on their 70's retro disco red glitter vinyl chairs, but it being the summer of COVID, I ended up drinking my fine coffee by the Tiger on Highway 10 (also packed full of citiots all doing the same thing at the same time, as they do).

While I was standing there I noted the new bicycle shop that had opened up a few doors down.  Ryan Carter, the owner of the new Ryan's Repairs, had some interesting kit out front, including a seventies banana seat bike with a single cylinder engine mounted to it.  I ended up chatting with him for a bit and had a look in his shop.  He'd only been up in Flesherton for a couple of weeks.  If you're up that way and you're interested in bicycles or even just some interesting mechanical engineering, drop in with your Higher Ground coffee and see what's what at Ryan's Repairs.





It was a longer than planned stop in Flesherton, but I eventually finished my americano and then I was off to Beaver Valley.  Highway 10 was bumper to bumper, but I dodged through town and only had a to do a few hundred yards with the sheeple before turning off onto empty country roads again.

Beaver Valley has a fantastic road (Grey County Road 30) that weaves down into it with epic views.  If you hang a right at the bottom and go on the dirt, the ride back up Graham's Hill is intense, particularly so this time as all the recent rain had washed it out leaving a stream cut down the middle of it that was tricky to navigate.  I ended up on the wrong side of it as it cut across the road, but even on my 'it's time for a change but no one has them in stock' Michelin Anakees, I was still able to 

The view out from Graham's Hill lookout was also worth a stop.  I went through there last year in the middle of autumn colours and it burned itself into my memory.  This time around everything was super green, but it's still some interesting geography to ride in our otherwise tedious flatness.

I looped back around to Grey 30 and came back down the hill without a slow mover in front this time before hanging a left and following the road out to Beaver Valley Road and the trek up to Thornbury.  I was there in the early spring but the harbour was closed in the early days of COVID.  I was hoping this time I'd be able to get myself right down to the water's edge.





I guess Beaver Valley Road isn't on everyone's GPS because it was fairly empty.  With a few big, high speed sweepers, it's a nice way up to the bay.  Ontario 26, the road that follows the shore, is evidently on everyone's radar because it was bumper to bumper.  After a brief stop to look at the bay...



... I stopped for gas in Thornbury, but the traffic on 26 was nuts.  Rather than sit in a line to get through
the light for half an hour, I zipped up the side and took a right back inland.  South out through Thornbury and Clarksburg (no traffic), I hung a left on 40 (also empty) and rode directly to Grey County Road 2, which would bring me back over Blue Mountain and into the Grey Highlands.  I'm still at a loss to explain why, when left to their own devices, most people just imitate each other.  I'm not sure what happens in their heads that makes sitting in traffic when they are surrounded by empty road make sense.

The roads south were also pretty empty, though I'm able to dispatch traffic with alacrity on the big 'ol Tiger.  Singhampton arrived in no time.  124 northbound had construction and what looked like a half an hour wait to get through it.  I was heading south then east and bypassed it.  I wouldn't have sat in it in any case.  A better way around would be to zip down Crazy River Road toward Creemore then wind through the hills of Glen Huron, which is exactly what I did.


 The big skies in the hills were getting dark as I headed south.  It was cloudy when I left, but driving north to the bay meant avoiding that rain, now I was riding back into it.  The clouds were ragged as I flew south on 124.


By this point I'd been on the road for about four hours and hadn't stopped since Flesherton, so I figured I'd give River Road from Horning's Mills to Terra Nova a go.  It was closed for construction when I tried it in the spring, so this would be my first ride on it in 2020.  Like everything else in Ontario these days, they've managed to fuck it up.  After construction the entire road is now a 50km/hr zone with community fines doubled signs everywhere.  I really need to move somewhere else.  I get that no one wants idiots ripping up and down the road in front of where they live, but a 50/community safety zone for the entire length of a road that has maybe ten driveways on it over 12 kms?  There must be money in the area.

Fortunately, Terra Nova Public House was open and could squeeze me in for a socially distanced soup between their lunch and dinner service.  The rain finally hit while I was sitting out back.  Big, fat drops splashing into my soup, but it was still fantastic (maple carrot homemade!).  It was a brief shower and it blew over quickly.  I was in and out of TNPH in about 20 minutes, and by the time I came out the road was dry again.  I puttered back along River Road, frustrated at the iron grip of government and then started the burn south west back home.



Blustery winds and ragged clouds north of Shelbourne, then it was down through Grand Valley, following the Grand River home to Elora...


The Tiger ran like a top.  The idle/stall issue seems to be a thing of the past.  It was a nice ride through some changeable weather.  It was also cool enough that I wasn't cooking on the seat, so I felt like I still had a lot in me when I got back.  The trip knocked the Tiger up to only 600kms away from hitting 80k.  It turns twenty years old in 2023, and I like the symmetry of it hitting 100k by then, so that's the goal.  This winter it'll get new shoes (if anyone ever gets Michelin Anakees back in stock again), and a complete service including all bearings and suspension.  It'll get an oil change too if anyone ever has Mobil 1 motorcycle oil back in stock again (finding parts during COVID is an ongoing headache).

I should get well into the 80s before the riding season's done, and then it'll be spa time.

Motorcycle Riding in Ontario: It Was The Worst of Times, It Was The Best of Times

I managed an 800+ kilometre loop through Southwestern and Central Ontario over the weekend.  The ride out and the ride back four days later were distinctly different, though they did have one thing in common:  gravel companies with little regard for public safety.

I began early on Thursday morning hoping to beat the heat, but even a 9am departure had me sweating in humidity fuelled mid-thirties temperatures.  On Fergus/Orangeville Road heading into Orangeville a gravel truck decided to drive into oncoming traffic so he could have a chat with his buddy pulling up on a side road.  He cut it so close the old couple in the Cadillac at the front of our group left ABS intermittent skid marks on the road and almost got rear ended by the guy behind them in an F150 who was too busy texting to notice events unfolding.  This is the second time an employee of Greenwood Aggregates/Construction has been a pain in the ass for us.  Last time it was a fist sized lump of gravel that cost us a $500 deductible to get the windshield replaced in my wife's car.  This time around I was in full-biking-radar-paranoia-mode, so I saw the whole thing unfolding and made myself some space by moving to the shoulder so the guy behind me didn't run me down in the heavy braking.  It'd be nice if the OPP spent a little time observing misdemeanours by Greenwood Aggregate drivers on the Orangeville/Fergus Regional Road 3.  If they can't take other road users' safety into consideration, perhaps they should have their licence revoked.

Rather than continue to enjoy the chaos of the busy-for-a-Thursday-morning regional road, I ducked onto a gravel side road (a benefit of riding the Tiger) and took the back route around to the bypass.  Being clear of traffic, even on loose, recently graded gravel always feels so much better than riding with jumpy, unpredictable pillocks in their boxes.  Bigger the box, bigger the pillock, and these days everyone drives the largest possible thing they can find.

I've been working on the Tiger's recent stalling issue, and thought I had it licked, but it stalled on me after getting gas in Mono Mills in the middle of a highway intersection, so I was on edge.  It did it again while making a left turn off Highway 9.  The key to my survival as a motorcyclist is my ability to respond to traffic quickly with awareness and agility.  A bike dying on me in the middle of an intersection feels the exact opposite as it suddenly makes me vulnerable and immobile; it feels like betrayal.  Some people online have suggested just riding around the issue, but I think that's absurd.  If you're riding something that can leave you dead in the middle of a turn, that's not something to ride around, it's something to fix.

Now truly fraught and soaking in sweat, I pulled over to get my shit together on a tiny side road before getting onto the 400 Highway.  My new COVID normal is to find a shady spot and have a stretch, a comfort break and a drink.  I pulled over onto Side-road 4 which had zero traffic and re-centred myself.  It was a lovely stop in a quiet farming area.  No sound of traffic and only the breeze stirring the trees and corn.  It was a Zen ten minutes that let me get my head on straight again.

The 400 north was surprisingly busy for a late Thursday morning, but was moving at warp speed anyway.  The inside lane was averaging 120km/hr.  I dropped into the flow after passing a cruiser parked under the overpass I used.  I guess he was only looking for people doing 160+.  By now the air temperature was well into the high thirties and the oppressive humidity had it feeling in the forties.  Even at speed on the highway I was always sweating.  I got to Barrie in next to no time only to discover that a single lane reduction at the Essa Road exit meant that the me-first GTA crowd had backed up traffic for 20 minutes because they all have to be first.  Massive trucks and SUVs (few people drive cars in Canada any more) were pulling out onto on ramps and burning to the end before trying to butt in ahead of where they were.  Being Ontario, I couldn't filter through and ended up sitting on sixty degree tarmac for the better part of twenty minutes in stop and go traffic under a relentless sun surrounded by air conditioned cagers who were making it even hotter, with a bike that stalled if I let go of the throttle.

I finally got clear of Barrie and things were once again moving at warp speed, with trucks towing boats passing me at 40km/hr over the limit.  Ontario highways are truly something special; a hybrid of Mad Max and a never ending grocery store line up of the biggest jackasses you've ever met.  But I was now clear of Barrie and Orillia and only had the wide open spaces of the north to look forward to.  I was evaporating sweat so much a cloud was probably forming above me, but at least I was in motion, until I wasn't.

Ten kilometres outside of Gravenhurst traffic came to a sudden stop again.  Why?  Ontario refuses to widen the bypass around Gravenhurst onto Highway 11, and we all know how GTA traffic likes to merge with grace and efficiency, so things had come to a stop, again.  At this point I was deep into fuck-it territory.  My plan to get up to the lovely 118 and cross over the Haliburton Highlands and down to my wife's family's cottage near Bobcaygeon was starting to smolder in a dumpster.  After sitting next to a Shell station for a couple of minutes on baking asphalt, I pulled in and looked at the map.  Oddly, the Tiger was now holding idle.  The ECU learns how to set idle when you reset it with a new fuel map, so maybe the Tiger had learned how to solve its own stalling?  I should be so lucky.

Gravenhurst Traffic
Early Thursday afternoon GTA traffic into Gravenhurst where all the citiots have to all go to the same place at the same time, all the time.  The old fella at the gas station told me it'd be a 40 minute stop and go to get through it on fifty degree tarmac.  Bigger is always better in the cager crowd.  See many cars in there?  Trucks and SUVs, all the better to hit you with while ensuring your own safety!

I had a look at the map and thought that Washago and south around Lake Simcoe and over to Kinmount would at least get me out of attempting a route that thousands of people in giant vehicles from the GTA were plying.  Highway 11 has lots of turnarounds to go south, which I've always found odd until today.  I was quickly able to get on the empty highway south and found myself back in Washago and heading down an empty 169 and then east on an equally empty 45.  The temptation is to say Ontario is under-funding infrastructure, and it is to a degree, but the real issue is the group think in the most overpopulated area of Canada, which I have the misfortune of living near.

Changing my mind on where I was going changed the ride.  I'd been aiming for unfamiliar roads, but that's not something easy to find in summer of pandemic.  The Tiger seemed to have changed its mind too.  At the odd stops at lights it was suddenly idling steadily and the pickup on throttle and vibes at speed felt better than they used to.  I guess the ECU had finally worked out the new fuel map.  I was still dehydrated and cooked, but I was on winding roads with almost no traffic.  Unfortunately, these were the same winding roads I'd taken last month to the cottage.  
I stopped in Kinmount because I'd done that last time and knew they had a public washroom in the park.  After another comfort break and as much water as I could neck, I sorted out the 360 camera and headed toward Gooderham on the 503 for a roller-coaster ride down the 507 and then into the cottage; this was the good bit coming up.

The sun was getting low behind me and I early evening was upon us.  I got to Gooderham just past 5pm and headed south on the 507, the Tiger feeling better than it had in months.  Just south of town I saw the inevitable sign:  CONSTRUCTION.  Unreal.  I'd just busted my hump for hundreds of kilometres of Ontario tedium and the highlight is dug up.

After some kilometres of gravel, some of it ankle deep because they're in the middle of resurfacing, I
got back onto the pockmarked but paved 507 and proceeded south.  The long shadows meant the worst of the heat was off me and I soon found myself in Noogies Creek, working my way into some of Ontario's prettiest wilderness.

The 14kms up Bass Lake road goes from two lane gravel fire road to a winding, single lane gravel fire road quickly before ending at the lake.  Ten minutes later I was neck deep in it washing off a day of sweat and frustration.

Four days later I was saddling up just past 11am for the return trip.  My cunning wife suggesting doing the 118 route backwards on the way home since no one from the GTA would be going that way.  To make it even better, it was a humidity free 22°C on a Monday morning.  The Tiger still had almost half a tank, so I skipped cutting back to Bobcaygeon and headed east toward the 507 on Peterborough Regional Road 36.

I was approaching the turn north on to the 507. Quarry Bay Stone was just up the road and a gravel truck had just pulled out fully loaded and was ramming it up through the gears heading westbound towards the group of traffic I was in.  Bucketfuls of gravel were pouring out of this piece of shit truck as it approached us, bouncing down the road at 150km/hr closing speed.  Remember the Millenium Falcon in the asteroid storm in Empire?   Now I know how the ship felt.  I was lucky to be able to duck behind the truck and car ahead of me.  I imagine both vehicles are looking at body damage and broken windshields.  I got whacked on the shin hard enough to knock my leg off the peg.  That's another win for my awesome, armoured Macna motorcycle trousers.  Not only are they cooler than any other pant I've tried, but they also prevented me from getting a broken shin and/or severe lacerations on my leg.

When I realized how many rocks were coming at me and at such a high speed I put my head down and my new-this-year Roof Desmo RO32 took the impact for me right on the crown.  The rock was big enough to ring my bell, but had I not ducked it would have hit me at neck level, which might have been fatal.  Other sharp bits of gravel clattered off my road side pannier and I got a big scuff on my front fender, but otherwise the Tiger dodged the rocks.  I glanced back to see more bucketfuls of gravel skipping down the road, bouncing off the vehicles behind me.  The road was covered in it.  The next day at home I thought about what happened and came to the conclusion: fuck those guys.  It's their responsibility to operate safely on public roads, and they aren't doing that.  That this happened with two aggregate companies suggests that industry has a real fuck-you attitude to the rest of the citizenry who are using public roads.  It made me angry enough to make an online report with the OPP.  It's two days later and I haven't heard anything, but I'm not holding my breath  They're probably too busy trying to figure out what to do with all their pay raises.


This is one of those things you don't think about so much at the time.  I wasn't bleeding too much and the bike was ok, so I kept going.  I wasn't about to chase the truck down and I was too shocked to pull into the gravel yard.  I would have just flipped out on someone in any case.  Biking requires a sense of inevitability and fate.  You control what you can and live with what you can't.  Glad I did the report though; fuck those guys.

The 507 was virtually empty and cool as I made my way north.  Being a week day I suspected they'd be working on the road and soon enough I came to the edge of the construction.  I had a nice chat with the girl doing traffic control and was soon off.  Since they were laying tarmac they'd just put down a thick layer of sand and gravel, so thick my front tire disappeared into it and the Tiger bucked.  Thanks to recent SMART training my wrist did what it was supposed to do instead of involuntarily grabbing the brakes, which would have been bad.  The Tiger leaned back on its haunches and the Michelin Anakees bit into the loose material and launched us through the wave of loose material.  My feet never even left the pegs and I like to think I looked like I knew what I was doing.  The guy behind me on a Harley wasn't so lucky.  Legs all over the place before he ploughed it to a stop.  He then cut across the road to the tire tracks and then continued slowly up the verge.

The construction was soon behind me and then so was Gooderham.  I'd taken Haliburton County Road 3 to Haliburton a few years ago when I did a birthday ride through Algonquin Park, and knew it was a good one.  It's not as long as the 507, but at least as twisty and in much better shape; it was a thoroughly enjoyable ride through cool, noon-time air with thermoclines down by the lakes that I could both smell and feel.

I got to Haliburton still reading above empty.  This new fuel map was richer and smoother than the stock map, so I'd expected worse mileage, but because I'm not asking for more throttle and what I did use was smooth and effective, my mileage was actually better.  I figured there would be a gas station in Haliburton on the 118, but I passed through and found nothing.  I was far enough out of town that riding back didn't appeal, so I pushed on to Carnarvon figuring there had to be a gas station there as it's at the intersection of two major highways, but there was no gas in Carnarvon either, so I ended up ducking down the 35 to Mindin to get gas as the gauge fell into the red.  I was able to put 19 litres in, so I still had the better part of 5 litres in the tank when I filled up.  I'd have tried for Bracebridge if I'd have had a jerry can with me just to see what the run-to-empty is on the new and improved Tiger.  As it was I was over 400kms into that tank and think I still had another hundred in it (the Tiger has a big 24 litre tank).  That had us rocking a 4.22 L per 100 km / 55.71 mpg consumption figure, which means I'm beating a Prius, and that's without riding for mileage.

Brimming with gas I rode back north to 118 with more vigour than I'd come south.  The Tiger was idling so well I'd forgotten to keep checking on it, and the new fuel map was giving it a spring it had been missing.  Passing a cement truck (front wheel getting light as I wound it up through third) onto the 118, we found ourselves rolling through muskeg and ancient stone as the road took fast sweepers left and right around the Canadian Shield.  At one point a couple had pulled over and were slowing traffic (which was just me) because a snapping turtle was making its way across the highway.  He was a dinosaur amongst dinosaurs.  Easily a forty pounder with a giant, spikey tail.  I'm not sure how old they get (the interwebs say they can approach fifty years old); this was an apex predator snapping turtles.

Having circumnavigated the turtle safely, the Tiger burst off down the road with a snarl.  I saw no traffic until I was within twenty kilometres of Bracebridge.  The 118 twists and turns so much there are few places to pass, so soon enough a pile of us were behind a lovely old couple enjoying their leisurely motoring afternoon in a large American automobile.  I managed to squeeze out a pass on the only broken line and then enjoyed clear sailing all the way in to Bracebridge, which is much bigger than I remember it, looking more like a Toronto suburb with big box stores than the remote Ontario town it used to be.  Maybe it's all our fates to one day be living in identical subdivisions all doing the same things at the same time while staring at the same box stores.

Bracebridge was a bit of a faff, with more lights and traffic than any other part of the trip, then I was clear of it and off to Port Carling.  One of my first long rides on the Tiger was with my son across Ontario when we first got it in the summer of 2016.  Back then we had a great stop at a lovely coffee shop and had chats with lots of people at the local tourism office.  Port Carling is a lovely little town, but COVID has taken its toll.  The coffee shop was gone, and the rest of the place was mostly closed, though this might have been a Monday thing as much as a COVID thing.

I ended up skipping town and stopping COVID-style at an empty side road in the shade for a comfort break and a granola bar and as much water as I could take on.  I'd been hoping for a hot lunch, but hot lunches are few and far between in 2020.

The ride south to Bala was trafficky but moved well.  I'd never taken the 38 west to the 400 out of Bala and was surprised to learn it passes through Mohawk land.  It was a nice ride on interesting roads which I spent mostly behind a couple of native one-percenters (badged vests and all) on Harleys.  They gave me a wave when they pulled over to their clubhouse which was nice, a lot of the too-cool-for-school cruiser types don't bother with the biker wave.

The 400 was what every highway should be:  lite traffic moving like it means it.  Traffic was cruising at 120 in the slow lane.  I flashed south to Horseshoe Valley Road in a matter of minutes.  It was 80kms of quick moving but with zero headaches because I bailed before Barrie.  Horseshoe Valley Road was doing culvert repair (a lot of government COVID support has been going into needed infrastructure updates, which is no bad thing).  It was only about a ten minute wait and I was off again.  I remembered the Strongville bypass and took back roads to Creemore where I made my last stop by the Mad River where it gets its name tumbling down the Niagara Escarpment for the last of my water, then it was the final hour and a bit home, but now I was back in the Tiger's natural hunting range on familiar roads.

Other than being pelted by another anti-social gravel company, it was a lovely ride back.  Mostly empty roads and in much more humane temperatures.  The Tiger ran like a top, not a single stall, and feels like a new thing with its software update.  I'd been having anxiety about it on this trip, but it's a multi-dimensional thing that can do everything from single lane tracks in the woods to superhighways.

I'm back home again for a few days for work conferences (all remote), before we're forced back into classrooms by a government that seems to have no idea what it's doing.  In the meantime though, I have two working bikes in the garage and the rest of the short Canadian riding season to enjoy them.  Life is good.

THE MAGIC ISN'T MAGIC

I've got vegvisir (viking runic compass) to prevent getting lost (and survive storms, perhaps including gravel ones), and a modern binding rune for good fortune in travel (the top one).  Online suggested that the modern binding rune doesn't have any real magic in it because it's a modern thing, which I find funny (magic?  really?).

Here's some perverse atheist logic for you: I don't have to believe in these things for them to work.  If they do work and they are why a hail of gravel missed killing me, then I'm annoyed because my technique should have been what saved me, not a rune.  One of the reasons I don't like religious thinking is because it takes success away from you.  I'd rather own my wins and losses directly.

Why would an atheist put runes on their motorbike?  (these are on my hand guards).  I like honouring my norse heritage with the first one, and the fact that I spent a cold winter day hand painting these on there is a form of mindfulness.  Even when I'm not riding, I'm thinking about what's important when out on two wheels:  knowing where I'm going and getting there safely.  These aren't examples of magical thinking, they're examples of psychological discipline... and I didn't get maimed by gravel because of situational awareness and defensive riding techniques.  Unseen magical forces had no more to do with that than they did cause the gravel in the first place.  That kind of thinking is turtles all the way down.

Triumph Tiger 955i Engine Remapping

There are a number of posts on this blog about working out the kinks in my 2003 Triumph Tiger 955i,
and 
this is another one.  I've been playing with the Tuneboy engine management software that came with the bike, which works well, is put together well and is easy to use.  In working with the Tuneboy kit I discovered TUNEECU, a more open-source option for programming your own engine maps.

If you've never wrapped your head around engine maps, they're not very complicated.  Tuneboy does a good job of explaining how it works in their primer that comes with their software.

Back in the day you had a carburetor that used screws and jets to set the amount of fuel that got metered into the engine.   If you changed altitude you had to start swapping hard parts (usually the jets that sprayed fuel) to keep the bike running right, and sooner than later you had to manually trim the whole thing to keep it running right.  Electronic fuel injection took that all away.  A computer under the passenger seat on the Tiger takes inputs from sensors in the air-box (barometric pressure), in each of the three injectors , the fuel pump, radiator (engine temperature) and a crankcase sensor to constantly adjust things to use the most effective amount of fuel to make the bike go.  Put another way, carburetors are a mechanical, low resolution solution to feeding fuel into an engine.  Electronic fuel injection is a responsive, high resolution fix to the problem of delivering the right amount of fuel to a motor.

Tuneboy map editor - you can change settings and tell
the ECU (electronic control unit) what to do under
certain circumstances.

A fuel map is a spreadsheet of numbers.  Sensors feed the computer what RPM the engine is turning at and how much throttle is being asked for and based on the number in the fuel map, the computer delivers a set amount of fuel.  The 'fuel map' is literally a map that directs the computer to deliver a set amount of fuel.  If you're at high RPM and have just shut off the throttle, a smart EFI system will cut fuel delivery entirely, saving both fuel and emissions, something a carb couldn't manage.  If you suddenly give the bike a handful of throttle at low RPM, the map will direct the fuel injectors to deliver an optimal amount of fuel as it picks up speed, whereas a carb will always just send a mechanically set amount of fuel based only on how much wrist you're giving it.

In Tuneboy's system, you can change fueling and ignition maps, and modify things like idle speeds. The issue has been that the only maps I can find for Tuneboy are the stock ones from Triumph, which were set up to favour fuel economy and emissions over smoothness and drive-ability.  Meanwhile, TUNEECU (if you can navigate their 90's style web design and atrocious apostrophe use) offers you modified tunes that can smooth out your lumpy OEM map.

Of special interest to me were custom edits that made the list and have been on there for 9 years.  I don't know who Deano from South Africa/SA_Rider is, but they know their stuff.  The map on there does wonders for your Tiger's smoothness and pickup.  It might use a bit more fuel if you're heavy handed, but the difference in motor operation is impressive and worth it.

I was unable to find a digital tool to transpose the HEX files from TuneECU into my Tuneboy DAT format, so I opened up the modified HEX file and transposed the numbers over to the Default Tuneboy 10120 Triumph engine map and resaved it.  You can find that modified Tuneboy DAT file with the TuneECU South African mode here.

Finding this stuff isn't easy, and it's only getting harder as these old bike recede into the past, so I'm hoping this post help you find what you need to get your Tiger purring again.  It did wonders for mine.

Even though the old vacuum pipes held vacuum, I swapped them out for some similarly sized clear fuel line I had (you can see them going from above each injector to the idle stepper motor.  The TUNEboy software also comes with a diagnostics tool (with very cool 90s graphics!) that lets you test the radiator fan, idle stepper motor (which moves up and down modulating the vacuum in that black thing to the left/bottom in the picture) and the RPM gauge.

You can find TUNEboy here:  https://www.tuneboy.com.au/
It comes with a cable that'll connect to your Triumph and is easy to get going, and comes with all the stock tunes.  It also lets you tune on a dyno, if you're minted.  It ain't cheap, but the minted guy who bought my bike new was, so he sprung for it and I'm still enjoying his largess over a decade later.

TuneECU can be found here:  https://www.tuneecu.net/TuneECU_En/links.html  Try to get past the out of control apostrophe use - they're better at software than they are at the speaking English goodly.
The older version is free, but finicky with Windows' old serial port drivers.  You can buy the app on the Android store for fifteen bucks, which seems perfectly reasonable.  You can then connect via bluetooth from a phone or Google tablet, though I understand you miss some connectivity that way.

It gets tricky these days finding the On Board Diagnostics (OBD) serial cable you need to connect the bike to the PC.  You can buy 'em from the UK, where people like fixing things.  CJ Designs in Wisconsin will sort you out with one too:  https://cjdesignsllc.com/?s=TuneECU

The modded engine maps for Triumphs on TuneECU can be found here: https://www.tuneecu.net/Custom_Tune_list.html

The TuneECU page goes into detail about how you might use the TUNEboy cable, but it requires so much messing around with knocking default Windows drivers out of the way and forcing others on that I wouldn't bother (I didn't).

Tiger Brains

The other day I was once again going over the details on the Tiger after taking the tank of for the billionth time.  Even though the stock pipes for the vacuum controlled idle system for the electronic fuel injection hold vacuum when I test them, I can't test that when they're on the bike, so they might be leaking where they join.  I happened to have some fuel line in the right size, so I've taken out the Triumph hoses and put these clear ones on instead to isolate another possible point of failure.

Once I got them in I fired up the TUNEBOY software and figured I'd run the idle control system test since it would move the plunger up and down and with everything off I could check to see that it's all working as it should,  except the ECU wouldn't connect to the computer.  I've done dozens of TUNEBOY adjustments now and know how the bike syncs with the PC over the serial port, but it wasn't connecting.  While trying some variations I turned the ignition on on the bike and the ECU made unfamiliar popping noise, and then none of the dash lights would come on (the running lights still do though).  The ECU no longer clicks off when the ignition is switched off either, which suggests it's not coming on either.

The intermittent nature of this failure always made my ass twitch in terms of it being electronic rather than mechanical.  Mechanical failures tend to be more consistent and easier to diagnose, and I've replaced everything around the idle control system now, so unless Triumph sold me a dickey idle control motor, which seems unlikely since the first one lasted 17 years and did over seventy-six thousand hard, Canadian kilometres and survived seventeen -40°C Canadian winters.  Assuming all the new parts are working as they should, an ECU that was losing the plot is as likely a culprit as anything else I've been chasing, and now it seems to have popped entirely.

So what do you do when your old Triumph's bike brain loses the plot?  Get another, I guess.  Used ones seems to be extraordinarily expensive and look to be in rough shape out of US used parts suppliers on eBay.  And for some reason they're charging twice what European suppliers are for shipping.  With that and the fact that The States seem like they're on the edge of a civil war, I think I'll be looking to the dependable Germans who have COVID19 well managed for a replacement Tiger brain.  If I'm thinking that, I wonder how many other people are avoiding business with the US right now.

But before I go that far, I'm a G.D. computer engineering teacher, so I'm hardly going to let an ECU go in the bin without having a go at it first.  If this is a short or something simple, I can solve that easily enough.  If nothing else I can see how the ECU is set up architecturally, but more often than not I'm able to get electronics I have to open up working again.  Time to flex my soldering prowess.

The most frustrating part about this is that I may well have solved the idle problem with replacement hoses, or maybe I didn't.  Maybe I chased down all of these hoses and parts for nothing and it was the ECU losing the plot all along.  Electronic Fuel Injection (EFI) is a wonderful thing, but the early systems were fragile.  There a lots of posts online about early Triumph EFI headaches, and I've added to them.

Guy Martin does a good special called The Last Flight of the Vulcan Bomber.  They grounded the last of these nuclear bombers in 2015 because they no longer had the expertise and technology too keep them safely air worthy.  In the show Guy talks about why there are plenty of older planes like Spitfires still flying when the Vulcan has to be grounded.  He says the Spitfire was made from bicycle parts you could fabricate in a shed, so they're relatively easy to maintain.  The Vulcan was an industrial machine with early electrical and electronic systems that were many times more complicated.  He goes on to talk about how the Vulcan looked like it came from another planet when only seven years earlier an Avro Lancaster was the state of the art.  There are performance advantages in these leaps forward, but there are also maintenance headaches that mean these early jets will never fly again.

Early fuel injected bikes are a lot like that Vulcan - they can do things earlier bikes can't like get better mileage, not need parts changed to ride at altitude and generally require less maintenance.  I just fixed up one of the last carbureted bikes, a 1997 Honda Fireblade, over the winter.  EFI was around then, but Honda wisely went for highly evolved carburettors rather than new, fragile and poor performing EFI systems.  I rebuilt the carbs, which are a complex but highly evolved four-carb set, and the bike runs like a Swiss (or rather Japanese) watch.  The EFI on the Tiger did the job without any attention for 17 years and seventy-six thousand kilometres including two rides into the Rockies - something no carburetor could do, but when it finally broke, boy did it break.  It's things like this that will make these first generation EFI bikes rare in the future.  Like the Vulcan, they're so complicated and difficult to maintain when they go wrong that they'll get retired from service where an older, simpler bike might still be fixable.
