Get an htb pipe and header along with the K&B 11cc disc carb for good bolt on performance upgrade. You will have to cut your lower a bit to make room for the header if you are not already running a pipe. You can get what you need from Joe at 707specialties. Check his web site for pics and prices. Good luck and show us some pics

happy boating
