Started falling on it’s face and backfiring when throttled. Starts and idles fine. Installed new carb and same issue. Any help or suggestions would be greatly appreciated.
Thanks for the responseYou should install a new one but unless it is an open Yamaha boot you are wasting your time. It will break in a few hours. You should pull it and inspect it. Look close and twist it around. The cracks can hid unroll you install it. If it was me I would go back to the mikuni and ditch the zoom zoom as well
