Get an inner rotor, 88se, Takegawa clutch and tranny, and ride fast.
i wanna see you ride...then ill tell what you need.
if you can handle it id go with a 117se motor. that thing fuckin RIPS!! or go with an 88se motor. Talk to SkinDonor on the board and ask him how much he has a motor for. im sure dirt cheap for some good stuff with a manual tranny. let me know if you get a new motor..ill buy your old one off you.
