I bought Simon's kit from him with the original jackshaft and used it with no problems for 15k miles. I sold it to another ceger (Auiotour) and after 100 miles it blew the seal and stripped the splines. He said one of the jackshaft connecting bolts was loose so I'm assuming it wasn't perfectly lined up (as the old style one had to be). Techinically I had no problems, but both Simon and Llane had problems with it before and after me. For roughly $1500 it was a great used buy, but definately in need of a knukonceptz upgrade.
