I'm going to trying turning air screw out, 172, and leaning the needle by moving the clip or maybe a leaner needle
i mainly trail ride, just can't get the thing to quit spoging!
HELP!
what oil is every one using?
Sounds like it's too rich. Do the needle change, air screw out to and maybe another one down on main jet size. I also run near 40:1 when I'm on the trial and drop to 32:1 at the track for higher revs. Your elevation m,akes a difference but you didn't post that, it might help.
start with the pilot jet first. You wont do any damage and it will make a hell of a diference, especially if you trial ride at the lower throttle positions
yea well what sucks with me, I dont foul plus and my bike runs good but it spooged like crazy, all out the silencer and where it connects to motor, crazy...
