Frequently Asked Questions

Q: Do I need any tools to adjust this fuel mixture screw while on the bike?
A: No. The extended, knurled head design allows you to adjust the idle mixture entirely by hand with your fingers.

Q: What carburetors are compatible with this Zip-Ty mixture screw?
A: This screw is engineered to fit Keihin FCR carburetors found on a wide variety of modern four-stroke off-road bikes, ATVs, and UTVs.

Expert Pro-Tip: When removing the stock fuel mixture screw, take care not to lose the tiny factory O-ring, washer, and spring nestled inside the carb body bore. Always verify that the old O-ring comes out before installing the new spring, washer, and O-ring combination, as doubling up on old seals will bind the screw.
