How many turns out is the air screw on stock YFZ450's?
I have cam mod, ESR + K&N, GYT-R pipe, 170 main, NCVP pin on 4'th clip,45 pilot, sea level 70 degrees. Runs really good now but have never touched the air screw. Running a 80% C12 mix for drags with stock compression.
Should I turn my air screw out a 1/4 turn or should I leave it stock? What is stock position? Thanks for any help.
Hope I remember my camera as I want to try to post a few pic's as this site needs more. I remember salivating when Selector posted his quad.
