kyle,,,, the transmission is not for amature attempts in my opinion,,,, buy a hwole bottom or motor,,, if you take it to the dealer I'll tell you from experience it will run you in the neiborhood of like $800 in parts alone from yamaha ,,,,, also in my opinion the tranny is the hardest part of a blaster you have to completely disassemble the engine and split the cases... how many gears do you have on it.... if i member right and correct me if i am wrong but it is 6 gears INCLUDING nuetral,,,, havent actually riden one in a bit but i think its actually 5
