Valve Clearance Cost @ 15k - Recheck Sooner?

Hey all, just did the 15k valve clearance check on my 2014 Vee and only one was out of spec! However I had a few that were on the very low end of spec - meaning one intake valve at .10mm and one exhaust at .20mm, and others that were pretty close as well.
Since they are so close to being out of spec potentially, should I plan to do another check in say 10k miles? Sooner? Later? At this point have the valves pretty much settled in to where they will so it won't change much anymore?
I debated making adjustments to the ones that were close but decided to go the "in spec is in spec" route and not change them all out.

I would have moved those two towards the middle while you were in there, especially the exhaust since they are the ones that tighten up most. I had to adjust at 15K miles and again at 30K miles, but no adjustments at 45K or 62K miles. I bet the intake valve won't change, but the exhaust valve may, no way to predict. Do what ever gives you peace of mind.

I would move all to the "loose side of the middle" the next time you are doing major work and then just ride the bike.

I personally would not check them earlier than the recommended interval. I suspect they will be right where they are now.

That said, if I went to the trouble to actually change shims in one valve, I would have adjusted all valves to the middle of the clearance spec. That likely would mean it would never have to be adjusted again.

I would have moved them all close to maximum. Loose valves are happy valves!

Check them again at 30k. They don't move after that in my experience.

+1 on that. I don't ever recollect seeing a valve loosen in normal use. I always opened valves up to the max clearance when checking them, just in case I didn't get back to them according to the schedule. Especially when they are a pain to get to. At worst, a valve on the loose end of the spec may be slightly noisy. A valve that is too tight will burn, fail to seal, and eventually need replacement, and perhaps head work.

Different motor and different adjustment procedures but the KLR650 (uses 29mm shims/disks) list to be adjusted at 15k miles. We believe Kawi did this to attract riders because they need to be checked at 6k miles. Having said that, we adjust at 6k miles to the loose end (happy, slappy valves) and when checked again at 12k and 18k they pretty much stay the same with some exception.

My 09Wee has 7500 miles. I'll check closer to the 15k interval and adjust accordingly. Based on what I've read on this forum, they should stay put after that first adjust for many miles.

Valve Clearance Cost @ 15k - Recheck Sooner?

Did the first check on my 650 at 30,000 miles. All valves were in spec but the exhausts were at the tight end. A friend helped me with the shims and put the exhausts in the middle of the spec. Intakes were already mid-spec. Iíll check them again at 60,000.
