I am with the university of alberta and we are building a 4-stroke snowmobile to compete in the C.S.C challenge in Jackson Hole. there is an article about it in the new supertrax. anyhoo we are using a crotch rocket motor and need a primary capable of 12-13grand. Does anyone know who can ballance/make clutches that could take this rpm? Whoever can will get advertising on our hood/trailer and so on.
