XR650L Air Screw?

Recommended Posts

Any ideas on adjusting the air screw on a 2014 XR 650L, I have done all the mods to get the motor running richer and smoother but can’t figure the air screw out, it’s not there?

Drill a small hole in the center of the cap. Then screw a sheet metal screw into the hole to get a grip on the cap and pull it out.

And like koolaid hinted, its a fuel screw, not an air screw. It meters fuel. Out is richer, in is leaner.
