Hey Everyone,
Tomorrow (4/26) I'm going to start tearing into my commuter for it's long over-due valve check. Bike has a little over 101k miles, last time I checked them was around 30k? But there were within spec since then. Here's a list of what I'm changing:
Spark plugs
Fuel Filter
Cleaning Air Filter
Valve cover Gasket
Engine Side Gasket
The specs/clerances are as follows: (FSM states to measure on a cold engine)
Intake: .11 - .19 mm
Exhaust: .22 - .31 mm
If I remember correctly, valves tighten over time. So after measuring them and swapping shims would it be better to have clearances on the looser side i.e. .19/.31?
