The valves on my lifan 110cc motor need to be adjusted. Does anyone know what valve the clearances need to be set at
Answer by Steve Y
Go with .002" inlet, .004" exhaust.
Answer by Soundra
What I do is to turn the screw till it touches the lifter. Then back it off 1/8th of a turn. It is a little more than spec and will require more frequent adjustments than the book. But, since I have limited tools this works just fine.
Answer by Buster Brown
Without a spec, I would be a bit conservative and use .003" and .005", or else the KTM method of 1/4 turn from closed. "A tappy valve is a happy valve."
