Importance of Valve adjustment

27241 Views 8 Replies 8 Participants Last post by  CatisCrap
Just thought I'd mention that after adjusting my valves,(intake was pretty tight) motor runs very strong and clean and gained probably 8 MPH and can fishtail around corners with ease now. I think its better to adjust on the looser end of the specs than the tighter end but please correct me if I'm wrong.

I run mine 1 thousandth on the tighter side of the tolerance. Turns over easier, and runs very strong. With my 750, if I go any looser than their specs of 6 and 8, I can't turn the motor over with the starter.
