Long Way Up & Valentino: Rage Against The Dying Of The Light

Ontario Motorcycle Mortality Statistics
Anyone who rides while impaired should automatically waive their insurance and health care coverage. A sell off of their possessions would go a long way toward recovering damages for victims . If we left drunk drivers to die on the side of the road and liquidated their assets to pay for their idiocy we'd see drunk driving all but end. Riding a bike while drunk is just shear idiocy. Operating a motor vehicle is a social contract, not a right, and your freedom to do it ends the moment you risk damage to someone else. If we aligned laws with this more tightly there would be less idiocy in our vehicular operation.
SMART Adventures: What Trials Bikes Can Teach You About Motorcycle Control
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!
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.
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.
On Going Historical Motorbike Research: 1930s Off road riding
Labour Day Weekend Ride: Georgian Bay
A 300km round trip up to Georgian Bay and back:
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...
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.
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).

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.

Triumph Tiger 955i Engine Remapping
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.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. LINKS 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). |
