Hey, I know I have seen it on here before, but can't find it now. What is the valve lash supposed to be set at for intake/exhaust? I am going to do first "tune up" and see if it helps my machine run a little better. Has about 530 miles, and a little top end noise, and rough start/ no start. Wanna check everything, but wanna make sure have the right specs. Thanks ahead of time.
