So first step remove the torpedo from the rear and stick in a bottle ?? This adds a new problem as the PAV WILL NOT LIKE IT so moved the needle in the carb down one still no repsonce from the bike???
Now got a lot of missfire in the bottle only when the throttle was shut down or you coast ??
Next step check the mount to the head from exhaust/silencer all seems fine still good seal still backfire.
So next up is the outcome is remove the PAV decat the downpipe move carb needle to lowest setting. No need to rejet unless on free flow AND BULL IS BACK AS IT WAS
