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.

Wahay!  A new ECU is two-grand, AMERICAN!  That's over $2500 Canadian!  The whole bike cost me three grand.  See what I mean about the costs of keeping emerging, fragile old tech active?

Moonbeam and Back: An In-Ontario Iron Butt & a Bike to Do It



The mighty Wolfe Bonham did a Moonbeam run this year as a part of one of his mega well-beyond an Iron Butt long distance rides.  I just popped it into Google maps and it happens to be a perfect first Iron Butt distance from home, and all in the province.

The starting Iron Butt is the Saddlesore 1000, 1000 miles in 24 hours.  They have a metric equivalent Saddlesore 1600 kilometre ride too.  The suggestion is to do a distance that can't be short cutted for credibility's sake.  Riding from Elora to Moonbeam and back is always going to be over 1600kms, no matter how you do it.  Another benefit is that by going up on Highway 11 through North Bay and back through Sudbury and on the 400, I won't be riding the same route twice.

The Tiger has become fragile, so I'm jonesing for a long distance weapon, not that the vibey and exposed Tiger was ideal for that, but it's what I had.  A few years ago Max and I rented a Kawasaki Concours14 for a ride in the Superstition Mountains near Phoenix, Arizona, and it was a glorious thing.  That Connie was a first gen C14, the newer ones have one of the highest load carrying capacities of a modern bike - so big that they could carry Max and I two-up again.  Another thing about getting back into Connie ownership (I used to own a C10), is that I'd have an excuse to frequent the Concours Owners Group again.


There is a low mileage (31k) 2010 current generation C14 for sale in Toronto with some cosmetic damage and a dodgy windshield.  I can sort out the niggles, and then this thing would eat miles like nothing I've had before.  There is a strange lack of Kawasaki Heavy Industries motorbikes on the Iron Butt finisher's list (Honda has six times more bikes, BMW over eight times more).  I want to represent!  I've owned more Kawis than any other brand to this point, so it'd also be coming home to team green.

This particular one is blue instead of tedious grey (Concourses tend to be very conservatively coloured), which appeals, I prefer a colourful bike.  The C14 has a number of optional touring pieces, including a variety of windshields, which is good because the slab on that Concours ain't comely.


Love the Milano from Guardians of the Galaxy.  The C14
would be getting similar higher visibility trim, especially
around those Testarosa strakes!
Fortnine has the National Cycle Vstream windshield for the C14, which would give me a smaller but more functional, better made and swoopier look.  The bike comes with a top box and panniers, so there isn't too much it'd need, other than sorting out the windshield and doing some touch up.  Seeing a blue bike, I immediately want to liven it up with some orange trim, Milano style.  Other than a full service and a few fixes, this bike is ready to do 100k.

The stock seat is already a comfortable thing, though I've enjoyed the Corbin on the Tiger so much I'd consider tapping them again for another custom saddle eventually.  The C14 Concours would be the biggest bike I've owned and could do something nothing in the garage can do right now, carry my son and I two-up while operating within the bike's weight capacity.  It would also be just what I need to make a run to Moonbeam and back in 24 hours as the summer winds up.

A Tim's Top Gear Rick & Morty Themed Travel Challenge: We're going to Windigo, Morty!

I'm a big fan of Top Gear, and I especially enjoy their travel/challenges.  I've always dreamed of planning one, getting people silly enough to commit to it and then making it happen.

In the summer of COVID I'm finding myself daydreaming of possible adventures, so I started poking around on the internet trying to find how far north roads go in Ontario.  Bafflingly, Ontario has never connected to its own north sea shore by road.  For a province that has thousands of kilometers of ocean shoreline, Ontario seems intent on convincing its citizens that it's land locked.  I'd love to ride 1000kms north to the sea, but it's not an option.  James Bay is roughly in line with Scotland, so its not like it's in the arctic.

In the meantime, it looks like Windigo Lake north west of Thunder Bay is as far north as you can ride in Ontario on your own wheels:



...which offers us a great thematic riding challenge!  It's time to go to Windigo (instead of Bendigo), Morty!  Here's the inspiration in case you're not hip to Rick & Morty:
Here's the Top Gear style WE'RE GOIN TO WINDIGO, MORTY! Moto Travel Challenge:
  • Each participant gets a $3000 budget for a bike and any farkles that must include a safety certificate.  Ownership is by WG2W Productions, pending the bikes return to Elora within 10 days of the event, at which point ownership is signed over to the rider.  Safety and taxes should be about $400, so that leaves about $2600 for a bike and farkles
  • Insurance and ownership is managed by the event
  • All riders must have a valid Ontario M class license
  • Camping equipment is provided to each rider individually based on a sponsored selection of gear (rider's choice)  Each rider will be provided with bear gear.
  • Each participant has to do any repair or maintenance on their own bike.  Only other competitors can assist.
  • Google maps says it's a 27 hour ride to Windigo.  Riders can only be on the road between 7am and 7pm, so the most efficient (and luckiest) should arrive in Windigo on day three in the morning.  At 12 hours per day of possible riding, 27 hours =  2..25 days of riding.  The earliest rider with a perfectly timed ride would arrive at Windigo at 10am on day three of the event.
  • Timing for the event takes into account speed limits.  Any rider caught speeding is disqualified.
  • Any overnight stops while riding to Windigo must be wild camping following leave-no-trace rules.  Proof of camp site cleanup must be included on rider GoPro footage or a time penalty is applied.
  • The rider who gets to Windigo (getting to Windigo means arriving at the lake on your bike and dipping a toe in) as close to 27 hours of riding after leaving the start line as possible, wins!
  • Riders can choose how to use their daylight hours to ride.  In the case of a tie, the rider to get to Windigo the soonest and closest to 27 hours of riding after race start wins
  • Winner gets a We're going to Windigo, Morty gold medal.  There will be silver and bronze finalist medals too.  Smallest displacement and oldest bikes who finish also get awards
  • Any participant who finishes this long distance riding rally and is able to ride back to the start line within a week of the competition end can keep their bike! 
...followed by 469kms of
challenging unpaved roads
to the end of all roads.
A paved odyssey...
This isn't an easy ride.  It starts with almost 1700kms of riding on paved roads ranging from the biggest freeway you can imagine to single lane tar patched, northern frost heaved back-road.  You've then got almost 500kms of riding gravel up to where all roads end at Windigo.  Trying to do this on a one trick pony like a cruiser would be entertaining, but likely unsuccessful.  This is a challenge for a multi-purpose motorcycle!

The 599 highway isn't Google car photoed once you get on the gravel, and you're constantly dodging lakes this deep into the Canadian Shield.  The closest I could get was this photo of the Mishkeegogamang Band Office, which shows a graded gravel road out front.  Fuel stops are few and far between, some cunning planning will be required!

BIKES

There are some interesting choices at the bottom end of the bike market in Ontario:




A bike that'll handle the off-road part of this trip, though it isn't built for the thousands of kilometres of paved road leading to the hundreds of miles of gravel fire roads.  Capable of handling the camping gear too.  Should come in on budget on the road.







Low mileage, in good shape and comes safetied, so you'd have a bit left over for farkles.  It'd chew up the pavement side of WG2W effortlessly, but that windshield might never see Windigo (Morty).







Big Honda touring bike, high miles, but it's a Honda.  It'd be a handful on nearly a thousand kilometres of gravel, but some people like that.  Should come in under budget and ready to make miles.  The paves stuff would flash by on this and it could carry camping gear with ease!





Low miles, Kawasaki dependable, in great shape.  The Versys is short for versatile bike system, just what you'd need to get to Windigo (Morty).  The 650 is a lightweight bike that'll handle gravel, and it has luggage and mounting points for some soft bags.  I'd probably be able to get it for $2300 certified, which gives me a bit for some soft saddle bags, then I'm off to the races!  This'd be my choice.  Might spill my extra cash on some 70/30 semi-off road tires.



There are lots of other interesting choices that you could get road ready for under three grand in Ontario.  Seeing what people choose and how they prep the bike for long distance, multi-surface, remote riding would be half the fun.  To stretch the choices there would also be trophies for the oldest bike and smallest displacement bike to finish the ride, so some people might go after those rather than the timed competition.

PRODUCING IT FOR TV

All bikes have GoPros to capture footage and all riders agree to provide at least 15 minutes of speaking to camera dialogue per day while in the rally.  All competitors have to document their camp build and take down.  There will be a production/sweeper vehicle with a trailer in case of any bike failures.  The vehicle will be able to provide technical support in remote areas and be designed for the gravel portion of the event as well as offer a central point for production and media management.

Competition begins when all riders have their bikes delivered to a shared garage space in Elora.

Film Schedule:
Day 1:  All bikes have arrived.  Bike familiarity and maintenance, bike paperwork taken care of, all riders and production crew doing piece to camera introducing themselves and talking about the event and prep
Day 2:  Bike familiarity and preparation, filming continues
Day 3:  Bike familiarity and preparation, finalizing ride planning, filming continues.  All bikes in park ferme at the end of the day ready for the morning's off.
Day 4:  7am Race start in Elora.  Filmed by production vehicle crew and GoPros on bikes.
Production vehicle stopping in Thunder Bay on Day 1.
Day 5:  7am start.  Production vehicle stopping at Windigo to await arrival of riders (riders who arrive early will have a major penalty, so no one should be there until day 3)
Day 6:  Production vehicle at Windigo Lake awaiting arrivals.  End of day 6:  close of event party on Windigo
Day 7:  All rider camping gear to be taken in by the support vehicle for a lighter ride back.  Sweeping the road south to Silver Dollar (the beginning of pavement).  All competitors camping at Silver Dollar Campsite that night.  Confirm end of event with all riders.
Day 8:  Retrace/sweep route to Thunder Bay.  End of rally event in Thunder Bay.  Riders who want to keep their bikes have 3 days to return to the workspace in Elora in order to claim ownership.  Riders who want to find their own way home can do so and bikes will be transported in the trailer.
Day 9:  Production vehicle sweeps south clearing any bikes that have been parked.
Day 11:  Any bikes that have returned to the workspace in Elora have their ownership turned over to their riders.

Stunt Riding is Easier Than You Think in Ontario (and everywhere else evidently)

We were at SMART Adventures Off-road Training last week.  You should go, same price as a day out watching professional sports-ball, but you're the athlete and what you learn there will raise your bikecraft to another level.  While there I got an opportunity to go out for a ride on the new BMW 1250GS with the legendary Clinton Smout.  The new GS is a thing of beauty and a very capable machine, but what struck me most about it was how high the handlebars are set; the bike is very easy to ride while standing on the pegs, which is one of the 'command' positions when riding a dual sport or adventure bike.  I'm a tall guy (6'3") and often have to bend too much to operate a bike from the pegs, but not on that GS. 


We switched to the big bikes after a couple of hours riding trials bikes, which don't have seats at all.  Standing up for that long on these super light weight, powerful and very twitchy machines pretty much wiped me out, so a chance to ride BMW's latest evolution of the legendary GS was a nice change.  It was a blisteringly hot day well into the mid-thirties Celsius and I was drenched after the trials gymnastics, so I did what I usually do and stand up on the pegs once we got moving to air out a bit and get a feel for how the bike moves.


Clinton doing pre-flight checks on the
BMW - it's a digital machine.
When we stopped for a coffee Clinton said something that surprised me.  A friend of his was charged with "stunt riding" for standing on his pegs while riding.  He wasn't doing anything silly or speeding, he just stood up on the pegs on a bike designed to help you control it that way.  This charge is an officer's discretion situation and the OPP officer who pulled him over who may very well have no understanding of motorcycling or this kind of dual purpose machine made the decision that this was stunting.  He fought it in court, but the judge told him if he wanted to stretch he should just pull over to the side of the highway and stretch, which is the kind of advice that'll get you killed.  Along with that bad advice he got whacked with a crippling stunt driving charge.  I can't imagine what this does on your driving record for insurance, let alone the fines and possible jail time.  This is the same charge as doing over 150 kms/hr on a public road!

I've frequently stood up on the pegs while riding in order to maintain a level of comfort by cooling off or stretching that would allow me to ride with better focus.  I've only done this on adventure bikes designed for it and there is no intention of stunting in this.  At other times I've done it to navigate particularly gnarly pavement and construction or provide greater situational awareness by better seeing what's ahead.  The types of bikes I ride are designed to use this variation in rider position to actually enhance control of the vehicle.  Ignorance of the law is no excuse, but ignorance of riding dynamics and best safety practices are evidently par for the course.


The only place 'motorcycle' is mentioned in the law is around wheelies,
otherwise generalizations about cars are all we get.
There was a recent local news article that talked about all the stunt driving going on in the area.  One of the infractions listed in from the Ontario Traffic Act where it looks at the definition of stunt driving is driving while not in the driver's seat.  The intent there is obviously aimed at a car, but Ontario likes to cast a wide net so it can charge citizens and tax them with fines without question, so the vagueness is left in there intentionally and it cost Clinton's buddy big.  This once again reminds me of just how aggressively Ontario pillories motorcyclists.

I'm very conscious of how physically challenging motorcycle riding is and consider it a priority to retain maximum focus and control of these potentially dangerous vehicles.  In Ontario, where riders can't split traffic and filter, and where temperatures in the summer can easily hit danger levels, the unprotected motorcyclist under the baking sun is forced to sit in stationary traffic and fumes and isn't even allowed to stand up to get some air when things move?  It's like Ontario wants to kill people who ride.

I've gone on rides at various times where road conditions are such that standing on the pegs actually helps me navigate circumstances and manage road hazards more safely.  Standing on the pegs can, as CycleWorld describes it, turn "you into a dynamic part of your bike" and "an active part of the suspension."  Thanks to Ontario's vague laws and officious police force and judiciary I can get had up for stunt riding when I stand up to correctly navigate terrible road surfaces (of which Ontario has many), road construction (of which Ontario has lots) or if I simply need a better look at what is happening ahead.  Situation awareness is just another one of the many benefits of standing on your pegs, but Ontario is more interested in charging citizens with harsh, non-specific generalizations that can financially cripple them than it is with focusing motorcyclists on safe operation.

The general advice online is if you need to stand just lift your butt a bit so you can make the argument that you aren't standing - you are and you're breaking the law, but at least you're putting your life at risk doing it wrong so it looks legal.  This doesn't offer you optimal control, but safe operation of a motorcycle isn't what we're going after anymore, is it?  The other way out is to have a nice, amiable chat with the officer and assure them that what you're doing is pertinent to the nature of the multi-disciplinary machine you're on.  You might not be able to make that argument with sports bikes or cruisers, but if your bike has any off road pretensions, standing on the pegs is something it was designed for that actually helps a rider manage difficult terrain while offering real benefits in situational awareness.

Next time I'm on an atrocious Ontario road getting my teeth knocked out by a loose and dangerous surface I imagine I'll do the safe thing and stand up to better manage it, but I better keep an eye out for the law while I do it.  Wouldn't it be something is safe vehicle operation was what drove our laws instead of vagaries that allow officious cops to make criminals of otherwise law abiding citizens?

Triumph Tiger 955i Valve Clearance Check

I just measured the valve clearances on the Tiger.  They're supposed to be checked every 20,000kms, I've put 27k on it since I've had it and who knows when they were done previously, so this was well past due.



Getting to the valves isn't that problematic since I've gotten gas tank removals down to under 10 minutes while I try and trace down this frustrating inability to idle.  Here are the numbers:

Cylinder             Intake                     Exhaust
             .13mm & .10mm       .20mm & .23mm
      2         .13mm & .10mm       .20mm & .20mm
      3         .13mm & .10mm       .20mm & .23mm

Intakes are supposed to be 0.10-0.15mm, so they're all within spec.  Exhausts are supposed to be gapped at  0.15 to 0.20mm, so a couple are on the cusp, though they're a tight 0.23mm (you have to push the spacer in there like you mean it - the .2mm is still snug, just not as).

Turning the engine with the rear wheel in top gear was pretty easy - don't grab the spokes, use the tire, you get more torque and it turns pretty easily.  As you turn the back wheel you get the cams pointing up, which is when you check clearances by sliding a feeler gauge under the cam and above the shim.



This Spurtar 32 blade feeler gauge from Amazon is a nicely made thing that offered me a full range of tapered ends that covered what I needed for checking valve clearances on this 955i Triumph Tiger. 

With the Tiger's timing pretty much to spec valve clearance wise, it suggests that my intermittent stalling problem isn't related to valve clearances.  Working on older bikes (and watching Car S.O.S.) has me well aware of what fails on older vehicles:  RUBBER!  Perished rubbers are Tim's go-to in Car S.O.S. when it comes to restoring an old vehicle - this Tim is thinking that's the issue with this 17 year old Tiger too.

I spent today putting things back together and double checking everything.  The vacuum system that feeds the idle control wasn't plugged in 1-2-3 (I had it 1-3-2).  That's something stupid enough that it might be the culprit.  At this point I don't care what it is, I just want the bike to idle to the point where I can depend on it to not stall on me and leave me hanging.

If I get it all back together and find that I'm still stuck with an intermittent stall I'm going to start systemically replacing all the rubbers in it.  Doing a deep cleaning on the fuel injectors is an idea too.  I ran into an old guy at Canadian Tire who swore by Sea Foam for cleaning fuel systems, so I got a can.  I've got some in the Tiger tank for the rebuild which will hopefully be done by tomorrow.  In a perfect world the Tiger will be back to normal and I can go after the valves in the winter if I'm so inclined.  If it's still stalling out on me, It'll be a perished rubber hunt next.

I'm already on it, replacing things as I find them...

It seemed like an extraneous expense when I got this set from our local NAPA auto parts shop, but having o-ring replacements at hand saves a lot of waiting.

A very shiny valve cover going back together again.  10Nm is all you tighten the valve cover down to.

Replacing the o-rings at the fuel inputs (I replaced the original terrible plastic ones with these aeronautically sound stainless steel ones shortly after getting the Tiger). 

I was hoping to get it all together, but I'm fabricating rubber grommets and trying to look into details as I go, so this is as far as I got in the 35°C heat.

Triumph 955i Stalling Issues Part 3, between a rock and a hard place

This started in June with intermittent stalling.  I've done all the obvious things like spark plugs, fuel and air filters, but the problem persisted intermittently, so I had another go at it in JulyThe Tiger has been my go-to ride for over four years now.  I've put over twenty-seven thousand kilometres on it, and up until this year it's been as dependable as a sunrise.

This week I chased down some other possible electrical issues.  The ECU was covered in muck so I cleaned it up and sealed the plastic underbody around it so it won't get mucky again any time soon.  I then found out how to test the ECU relay under the seat:

Everything else is sorted on the bike, so I'm down to the valves, which I really should have done in the winter.  I'm now between a rock and a hard place since I'm not sure I'm hanging on to the Tiger and it takes weird, old 25mm over bucket shims that Japanese bikes haven't used since the '80s.  Modern bikes use much smaller under bucket shims.   My nearest dealer is far away and dropping off the bike there would be a real hassle, so I'm looking at getting the Triumph valve shim removal tool T3880012.  But you don't need that if you're willing to remove the cams, so now I'm elbow deep into pulling most of the top end out if I want to avoid getting a special tool for a bike I'm selling on. 

On the other hand, one of the reasons I got into bikes was to get back into mechanics, and any self respecting rider should know how to do valves, so I'm kinda keen to do the job since I haven't done it yet.  I'm just shying away from sidelining my long distance motorbike in the middle of a too-short Canadian riding season while I wait for COVID crippled parts delivery on a 17 year old European bike.  The valves need doing anyway, but doing them might still not sort out the stalling issue, which would be very aggravating.

If I can move the Honda on I'd get the C14 Concours I've been eyeing and then the Tiger could take as much spa time as it needed.  I just had the Honda up for a few days in the four thousands, which is high for what it is, and only got an offer for a trade.  I'm going to put it up this week in the threes and see if it goes, then I can do some shuffling and take the weight of expectations off the old Tiger.

Some 955i engines are under bucket shims, the Tiger has over bucket shims (which is why the tool is needed if you don't want to remove the cam):  https://www.triumphrat.net/threads/05-955i-valve-shims.6986/

BikeBandit has the tool (1-2 week wait, and a 25mm shim set for $335US/$455CAD because even though the US is making a mess of COVID19, their currency seems to be immune to their poor management.

At this point I'm stuck between over four hundred bucks in tools, parts and the opportunity to do my first valve adjustment and whatever Inglis Cycle gets back to me with costs wise - though that'll also include having to get it over 140kms down there and get it back again on another day.  If they get back to me with a price north of $600 and a long delay in getting it done, I'll be going after the tools to DIY it, though I don't want to go crazy with a fancy set of 25mm shims when most modern bikes don't seem to use these big over bucket shims any more.

I'd go with Fortnine, but for some reason they're selling the identical shim kit to BikeBandit ($179US/$243CAD) for $278CAD. 

If I can move the Honda, I could get the C14 Concours and then have time to work on the Tiger without depending on it as my main long distance tool.  On the other hand, selling the Honda means I've just sold the only bike that's working right at the moment.  The Tiger picked a bad time during the summer of COVID to tighten up on me, though I'm well past when the valves should have been checked so I only really have myself to blame.
