Carburetor for a CCW

A quick diagnostic is to run the bike with the choke on...if it runs better/throttle response then the jetting is likely to lean.

when you play with pilot jetting then the A/F screw will need adjusting below 1/4 throttle range and idle.

after that you can play with needle position and main jet.

I'm no expert...been trying to adjust my nibbi carb for months after the 70mm big bore kit.
