My '94 K75 has 22,000 miles on it. I checked the valves for the first time last week and the intake valves were all nicely within spec, but all three exhaust valves were over .30 mm. I was surprised given the low miles on the bike, and thought maybe some carbon had fallen down between the valves and seats so I buttoned everything up and took it for several rides.

Today I checked them again and confirmed my earlier measurements:
#1 exhaust (front) .37
#2 exhaust .33
#3 exhaust .32

I'm assuming they need adjustment, but I've also heard it's ok if the exhaust valves are a little loose since they tend to close up over time, but .37 seems like a lot.

The bike is running fine.

Suggestions?
