Bike won't idle correctly - backfiring badly... Runs ok off idle. Installed an adjustable fuel mixture screw with no effect on the back firing. Pulling the choke stops the backfiring. But, that does not make much sense to me if flames are already coming out the exhaust. Float bowl height been checked, cleaned carb twice, checked the cam timing. What are next steps? Air leak, take carb apart again?.. The last thread talked about an air leak at the exhaust joint. Would that cause the backfiring with flames shooting out.
Any suggestions?
Thanks
