WOW! Valve adjustment
« on: April 22, 2018, 11:24:11 pm »
True confession time. I don't check my valves as often as many others and as often as suggested. I did the first valve adjustment on my 2011 C-14 at 50k miles in 2014. I replaced a few shims but nothing major. I'm just doing the second one now with 125k miles on it. EVERYTHING IS WITHIN TOLERANCE!!! I'm extremely impressed after 75k miles, and not easy miles, all the valves are in spec!! I don't know if anything we do, oil type, gas, riding style, etc. can make a difference on how the valves stay in spec?
But I'm surprised and impressed. And I had a complete shim kit on hand this time. Maybe that's the secret, be prepared and you won't need them.

I think that's typical.  In my experience the valve clearance tends to stabilize after 50K miles or so.

Nice report, Woodie, and good news.

I had dealer do the 1st and 'only' intended valve inspection of my 2011 at 33,000 miles.  The tech was experienced with C-14 as he was the go to guy for the local police dept C-14 repairs/service.   At 33,000 he said 3 of my bike's valves were out-of-spec slightly.  He replaced all shims to my requested settings so they would never have to be re-inspected (per my judgement / comfort level).

I am curious if one or both of you set to the loose side of the spec??  Just completed my first at 53k and I only had a total of five out of spec. I was a bit surprised and I was a bit more surprised that only two on exhaust.
Thank God you're alive every time you arrive!

Excellent info Woodie. Mine were all in spec at 26,600 but I adjusted them to the loose end. I don't plan to open it back up for a long time unless of course something goes wrong.

Always try  (withing reason of course) to have all valves adjusted to the 'loose' end of the spec and get a shim map done for future reference.

My valves were done on close to the same schedule as the OP's with completely different results. 1st adjustment was at 64,000 & 8 were tight. 2nd adjustment was done at 120,000 with all of them tight & 2 with almost no clearance. 3rd time at 195,000 & all was good.

No more adjustments for me.

Cliff,

Curious, did you guys notice any difference (start up/Idle) after the adjustment was done?

Toward the end of the next season mine will be due. I live in an isolated area in NE British Columbia and MC mechanics are not that common. The mechanics mostly work on dirt bikes, snowmobiles and ATVs. My Kawi shop recently changed hands and the new mechanic is not interested in the job. Even that mechanic is 2 hours from my house and I would have to spend the money to live away from home for at least 2 nights if all went well.
My other option is to go to the big city and go to a dealer in Burnaby BC. He has a great reputation and I have faith he could do the job properly. If I were to do that it would be 2 days to get there and 2 days to get home and at least 2 days in Burnaby. 6 days of living away from home and the cost of the value job would be somewhere in the neighbourhood of lots - I believe it would be about 30% of the bike's value. By the time the second value job is due, the bike will have depreciated further and the costs between the two jobs would exceed the value of the bike.
I did my C10 and it did cost a small fortune. In hindsight, I would have been better off saving that money and putting it it toward my current bike.
Doing the work my self is a total non starter. I don't have the place to do the work nor the tools. I have no mechanical skill whatsoever and unlikely to acquire any at my age. I still have at almost a year before I have to make that final decision.
Decisions decisions!

Why is it desirable to set the clearance on the loose end of the spec range ?  Does the clearance always decrease ?

That has been the usual experience. Excess clearance will become evident by noisy valves. No clearance will become evident by loss of power due to engine damage
