I used to race blasters idk if you guys have ever done this carb mod but its cheaper than getting a store boughten kehin or mikuni. But purchase a 1996-1998 kx 125 carb. Use your stock cable and all but you must use the carb slide and top off of the kx. Iused this and had a ama legal blaster making 41 hp. I was just throwing in a few sense.
