Kawasaki Concours C14 1400GTR Valve Check Part 3 - Putting it back together again

It's a slow process putting all this back together again. Even with a prolific number of photos and copious notes here on the blog I'm finding this a fiddly and frustrating process. My current plan is to get everything plugged in, top up the radiator and run it to make sure it's back together right before buttoning it up (there are a f(@# ton of  buttons).

The latest fun has been plugging the plethora of plugs over the valve cover back in.

I've got a couple of plugs (21) left after connecting everything else. The question now becomes: are oxygen sensor plugs not used on a 2010 Canadian market bike? 

Got the plugs in, except for those two top left of the rat's nest.

Here's a close-up. That white one has me baffled but perhaps it's the front cam sensor.

Tomorrow (assuming the late March ice storm we have in store doesn't throw us back to the stone age), I'll check for oxygen sensors on the exhaust, and if not there I'll know that one of those plugs is probably unused.

The ice storm was persistent but mainly pretty - no hydro lines down around here.

Other things to check are the front cam sensor (7-R on the diagram) which was very difficult to reinstall with a new o-ring. That plug is probably dangling down the front and needs to find a mate on top of the motor (looks like it's plumbed in under the front plastic guard). If that's my missing plug and the other one is an unused oxygen sensor then I'm about there.

After that gets settled I'll do one last look around for anything I might have missed before topping up the radiator and seeing if this thing'll run. If does I'll reroute the wires properly and should have it back to a point where I can start reinstalling all the fairings - which is a whole separate pain in the @$$, but at least one I've done before.

Then things get philosophical. Work has picked up and I don't have the patience or headspace to spend hours each weekend keeping these old bikes in motion. The temptation is to get $10k (CAD) between them and then buy something that can go when I need it to without so much TLC. 

I can save the wrench turning for when I retire. I enjoy working on them but trying to do a job this complex when I'm having to leave it for weeks on end while travelling makes a difficult job more so. Had I the time and space to do this daily when I wasn't juggling a demanding job, it'd have been an entirely different experience.

I'm loving the travel opportunities and my work is something I enjoy, but the deep bike maintenance doesn't fit with it at this point.

Haliburton was magical...



Flying out to the maritimes is never a bad thing...



...but those weeks away mean I'm coming back to an incredibly complicated job sometimes 20 days after I last touched it.

I've never made enough to be sentimental about vehicles and keep everything (I'd rather put those resources toward travel anyway). Time to simplify the bike stable to let me focus on riding when I can squeeze it in. I'll save the time suck that is older bike ownership for when I have more time to suck.

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:


That's the main how-to test Triumph 955i relays video, here are the two follow up videos: https://www.youtube.com/watch?v=TwkhX461GjM   https://www.youtube.com/watch?v=cDmh7FdpDDQ

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/

Shim sizing on 955i Triumphs (25mm over bucket shims are hard to find!):  https://www.triumphrat.net/threads/2000-955i-shim-diameter.230758/


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.
