Decel Popping on X4R. Help

Recommended Posts

Have an 08 x4r with 160cc. When I left out of the throttle the engine pops. So obviously it's running lean somewhere. Where do I need to fatten it up to get the decel pop out of it?

Check for a air leak between the Pipe and head, also check between the carb, manifold and head.....both are Common

what are you running for jets

stock pilot (not sure what it is), 115 main. The main and needle are good. I think i might have a leak at the header pipe b/c the flange on the exhaust is bent and it sounds like a small exhaust leak.
