How're the valves looking on your 200k bike, Chaos? Original engine still, original top end, and some clearance left still?

I recently checked my shims and have at least 0.5 mm of shim reduction potential left after 160,000 miles.

All original, some of the intakes still have their original shims I think.  Last adjustment I replace 2 exhaust valves, don't remember exactly but not close to running out of clearance yet.  Usually that's only a problem if they run tight for too long.  Did replace the shift drum and shift forks around 100k, early transmissions had bad heat treatment or some issue there.

i was aware of the mileage, but not too concerned, if that makes sense. 10k/year does mean it is ridden. always a good sign. no worries....the hunt continues......
