It took the better part of four months over the winter thanks to lots of work travel stretching things out, but the C14 is back together again and runs like a top. The engine doesn’t feel as tight, which makes sense as all the valve shims needed were to resolve the overly tight valves.

The Bay of Fundy near Saint John (latest work trip) |
It still does the clatter when you first start it (it’s to do with the cam chain tensioner needing oil
pressure to fully engage – it’s part of the engine design). The bike has always done that but now that I’ve laid hands on the thing itself it’s helpful in understanding how it all works. Knowing how complicated just the top of that motor is gives me a new sense of satisfaction hearing it run well.
I’m back from yet another work trip but managed to take the big Kwak for a spin last weekend and it pulls like it always has (which is to say like a nuclear missile). Today I’m going to finally do the oil change it was owed last fall and we should be on track for regular use this summer.
The question now becomes do I sell it on during the riding season or keep it having done this soul crushing maintenance job. Based on what I saw in there I’m betting I was the first to do it (at 45k kms). Considering the complexity of this job, I can understand why.
Part of that decision will come down to whether or not I’ve solved the Tiger’s fueling issues. If I have, I might sell the big (and expsnsive to insure) Kawasaki and do the summer on a dependable Tiger, though the C14 is a much more comfortable two up appliance if anyone wants to come for a ride with me.

A confirmed fix on the Tiger’s aging fuel injection system would make me consider going to one bike this summer. |

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 trying to button 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 they 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.
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. 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 runs like a clock 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 I’m 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 in my life.

…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 buy (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 that in. I’ll save the time suck that is older bike ownership for when I have more time to suck.

Last fall I took the fuel injection apart on the 2003 Triumph Tiger 955i. It wasn’t fueling properly and was unrideable. I barely got any mileage on it last season, so I replaced every o-ring in the system and got a new fuel pump for it. It also got new throttle and clutch cables last year. If this last hail Mary attempt to resolve the atrocious fuel injection on this old bike didn’t work, it was out the door.
The good news is it fuels nicely again for the first time in a year! I’ve still got to tune it and get the idle right, but it feels fantastic. Look back over the posts in December and earlier to see the details and where to get parts. If you’re trying to keep an old Triumph 955i on the road (Triumph doesn’t support them with parts any more), try this, it seems to work!

I feel great shame. I wrapped up this year’s Ontario Library Association super conference a few weeks ago, but my Kawasaki needed me and I’ve been neck deep in engine heart surgery instead of reflecting on this fantastic conference. Mechanics that my life depends on is sufficiently engrossing.
This was my second go at the OLA Super Conference, I last went in 2023. This year, like the former one, was remarkably emotional. You can’t help feeling that these are the front line people trying to hold civilization together even as it seems determined to tear itself apart. I’m left dizzied by the size of the fight against them.
Tech billionaire oligarchs are leveraging bottomless resources to direct a biblical flood of idiotic panic mongers who are happy to churn out disinformation that buys political victories. Once in power they have the tools to dismantle the critical thinking based education that we all used to aspire to.
Nothing is easier to incite than ignorant, misinformed, angry people. Our tech overlords have designed systems that encourage propaganda and reduce people to shallow, self-contradicting talking heads. I’ve been struggling to get pedagogically meaningful digital literacy into more classrooms throughout my career, but I’m beginning to realize that this is contrary to the direction society is going. Swimming upstream against this big money gets tiring in your mid-fifties.
Libraries standing against this political onslaught are having their resources systemically cut because libraries are precisely the institutions we designed to stop this sort of thing. How do you win such a one sided fight? I’m beginning to think that the democratic elections being gamed by this process can’t produce governments capable of stopping it, and I’m getting all Asimov-Foundations about it. Perhaps it’s time to save what we can for civilization until we start rebuilding again. And yes, these are my thoughts as I watched the Ontario Library Association standing against book bans and funding cuts.
Belief in the mission is one way to keep up the fight, but everyone seems worn thin by the effort. Keeping a strong front becomes difficult when your allies dwindle and everything you’ve built around literacy and critical information analysis is dismissed as meaningless. We live in interesting times. Being able to tie one on at the evening social with the brilliant women leading this fight was a highlight.
Carol Off‘s closing keynote was earth shaking. I wish they’d put it out so more people could hear it. Her retirement from As It Happens on CBC coincided with the rise in hate and division we’ve seen around us. Her talk cut to the quick describing the mechanics of this nastiness in vivid detail. It was a much needed rallying cry even as the barbarians hammer at the gates.

I’d signed up to present at the conference because I wanted to demonstrate (rather than just talk about) the importance of government, civil society and industry working together for our mutual cyber well-being. If you think that’s not a priority, 2025 is only a few weeks old and dozens of Canadian school boards have already been crippled by cyber-attacks, most of which depend on clueless users to get in. The vast majority of our cyber woes are a human education problem, not a technical one.
In the spirit of cooperation I reached out to many cyber organizations, but the common response seems to be a shrug when you’re sitting on a comfortable amount of funding, which isn’t very mission driven of them. I did connect with Debra at Knowledgeflow who is nothing but mission driven and she worked tirelessly to help build our collaboration in a country designed against working together. This ended up being our pitch for the talk:
To demonstrate the width of our collaborative approach, Marie at the Canadian Centre for Cyber Security joined our motley crew along with Cheryl from Cyber Legends. This gave us a full complement of cyber expertise from federal government, civil society and private industry. I can only shake my head at the many other not for profits, industry and provincial organizations who weren’t interested in participating because they’d rather just do their own thing poorly. Gaps caused by these little fiefdoms are why Canada is considered a prime target in global cyber-crime circles.
You might think that school boards are ‘doing’ cyber education locally, but the material I see (if there is any at all) is reductive, outdated, performative and not at all pedagogically valid in terms of teaching skills. Most of the cyber awareness stuff being trotted out locally looks to be made by people with no background or experience in cybersecurity. In many cases the cringy media they produce doesn’t look like it was made by anyone with an instructional background either.

Debra has this slide up in our presentation and suggested that these kinds of systemic failures aren’t something that individuals can influence, but I disagree. If the vast majority (research suggests over 80%) of breaches are caused by someone clicking on something they shouldn’t and letting criminals in past otherwise effective defences, then a skills based approach to cyber-education would also reduce these kinds of headlines! |
Our talk can be found here: https://knowledgeflow.org/wp-content/uploads/2025/01/OLA-Conference-Cybersecurity-Isnt-a-Scary-Word.pdf and includes piles of material designed by cyber specialists. Whether you’re working with post-secondary, K-12 or even with adults, you will find credible material designed to teach actual cyber skills rather than questionable performative marketing material that checks a box.
A heartwarming moment on day two was seeing Joseph Jeffries and Jennifer Casa-Todd recognizing the yawning digital skills gap in our education systems and tackling digital skills head on with the Canadian School Libraries. Seeing this happen across provincial lines gave me hope as this doesn’t happen a lot in the true north siloed and self-interested.

After what seems like weeks of disassembly (because it has been), the C14 valve job is finally turning the corner back towards reassembly! I’m pushing to get it around the corner because even with all of this documentation I still want to have muscle memory of how it came apart when I put it back together. Today the cams came out along with the shims and everything got measured, so it’s time for some maths!
The process of taking the cams out is pretty straightforward, but like everything else has twice as many fasteners and bits to it than you’d expect.
![]() |
Caps off revealing the cams. With the tensioner removed (notice the slack in the chain) you can slip the cams out from under it. |
…and finally, I’m at what this whole production has been about: the shims under the cams. The caps are suctioned in with oil, but if you give them a turn by hand the magnet picks them up easily – the shims are underneath.
What the gaps are supposed to be: SPEC: exhaust valves 0.19 – 0.24mm Intake valves 0.12mm to 0.17mm.
red = tight, white = spec, pink = on the cusp of tight: most are tight so will need slightly shorter shims to make a bigger gap, but we’re talking fractions of a milimeter here.
0926-1391: 215mm x 1 0926-1392: 220mm x 3 0926-1393: 225mm x 9
Here we go again:
C2 I1: 2.20 (=0.16 gap) C2 I2: 2.175 (=0.17 gap)
Under $30 US. Even with the conversion, shipping, customs (and now tarrifs), I’ll still be miles ahead. The site is a joy to use, they sell individually AND at a higher resolution than anything I could find in Canada. I’m book marking https://www.rockymountainatvmc.com/

I was busy at work with conferences, but got back for a Sunday afternoon in the garage. I’m trying out a new kerosene heater that seems to have solved my cold weather issues.
Once I had it into double digits Celsius I finished multi-checking the gaps:
Confirming the first round of measurements:
SPEC: exhaust valves 0.19 – 0.24mm Intake valves 0.12mm to 0.17mm.
red = tight, white = spec, pink = on the cusp of tight:
Cyl 1 Cyl 2 Cyl 3 Cyl 4
EX 0.18 0.18 0.2 0.19 0.19 0.19 0.19 0.21
IN 0.15 0.14 0.13 0.13 0.10 0.13 0.11 0.12
Things are pretty tight. CoG has good resources on shim details. Tomorrow the cams come out, I measure what shims I’ve got, do some maths and order new shims for the tight valves. This means that perhaps next weekend I can turn a corner and actually start putting this thing (which is looking like a disassembled Concorde) back together again!

I was (of course) hoping that the valves would all be in spec, but after a first round of measurements that is (of course) not the case, so this open heart surgery is going a step deeper: the camshafts are coming out. No point in getting in this far unless I sort everything while I’m in here.
Concours 14/1400GTR exhaust valves need to have between 0.19mm and 0.24mm of clearance. The intake valves need 0.12mm to 0.17mm. Looking at the notes below, I’m out of spec (tight) on most of them, making me wonder if anyone has ever been in here before. This one has 45k kms on it but it was semi-dormant when I found it. Most of the mileage was done in its first five years then it sat a lot. Alas, this is probably the case for most bikes.
Looking at this with red being too tight, white being in spec (anything on the edge I made pink), it’s clear that C14s get tighter as they go:
Cyl 1 Cyl 2 Cyl 3 Cyl 4
EX 0.18 0.18 0.18 0.19 0.19 0.19 0.19 0.22
IN 0.14 0.14 0.14 0.14 0.09 0.11 0.11 0.12
Now that I’ve got a round of measurements, I’m going to do it all over again (that’s what the pink notes are at the top of the handwritten bit above – the second round). Measure twice cut once and all that.
I hope to have confirmed everything this week and then I’ll order shims to get everything in the sweet spot. Or not…

It was -35 with windchill (-22C actual) last night. Will be again tonight, so I’m not going into the bloody garage! |
Incredible that 5% of one millimeter is the resolution this machine works within, but what amazes me more is that even at a fraction of a millimetre I’m still sticking a bit of metal (like a caveman) in to measure these fine details. Why don’t motorcycles make use of the mechanical precision used in car engines for the past quarter century and automatically adjust valves? Good question.
