Okay, this isnt helping much. Haha I've got no idea man. I wish i had a warrior, four stroke reliability, still yamaha, andddd reverse. How much did you get it for?
Yeah not many people know but thats actually where the banshee motor came from....
Anyways back to topic. Get a pipe first (anything but FMF unless you are really cheap) and then get a little bigger carb 28-32 and jet it correctly. Depending on what pipe and carb thats going to be like 400...
