As above my 400 exc is popping and banging on deceleration. I’ve checked the header to cylinder interface and it all looks good, could the header to silencer joint be the issue? That assumes my assumption of air leak is correct.
The only thing I’ve done to the bike is clean and rebuild the carb and she’s running lovely apart from this popping and banging. I also did the O ring mod on the accelerator pump which has eliminated the bottom end bog.
Any suggestions
