This ones important. The bikes service manual saids to do it every 6000 miles. I checked mine at 5600 miles and found two of the valves to be a little close (shims). Def get them checked its real important. Best case scenario you'll just loose power, worse case you'll burn a valve out, bend it or just pop ya engine.
New owner here. I was searching the site for just this information. I have a hard time believing the owners manuals 3,100 mile recommendation. Didn't think anything could be worse than a Kawasaki. After the initial 600 mile adjustment should I be good for 6,000 miles?
Jetboy, I've been tracking mine since the 10,000km mark, and they didn't change by more than 0.03mm in another 12,000km. Curiously, the gaps are increasing.
When I changed the cam chain at 25,000km, I measured each shim, and checked the clearances. 3 exhaust valves were at the top of the range.
At 30,000km, I'll check them again, and any outside the range will get new shims. A painful job, 'cos the cams have to come off to do it.
So I guess what I'm saying is, from my experience, checking every 10,000km is often enough.
