Idle Question

Brian_Bowles
My 1986 YZ125 runs great and starts without the choke when cold. After warming up the idle is just a bit too low to keep her going. The idle screw is turned all the way in. What options are there to get the idle up just a bit.

Sounds like you’re too rich on the pilot circuit... drop down a size see if that helps...This is assuming that your engine has good compression and no air leaks etc... also what is the air screw set to?

I believe the air screw is all the way in. How do I tell what size pilot jet I have? Is it marked on the jet?

If the air screw is all the way in, no bueno. Bring it out at least a turn and a half for starters. Part of the richness right there. Where is the clip set on the needle ?
