Just received a torque converter I bought on EBAY. $64 and free shipping. It is almost a copy of the one supplied with the 212cc monster kit I bought from Gasbike. All parts are interchangeable except for 2 Items. The shaft that supports the large pulley is to short to put a sprocket on the back side of the mounting plate so the only drive sprocket you have available is the one between the mounting plate and the large pulley. The other are the 2 sprockets supplied with the kit are #35 12 tooth and #41 10 tooth and won't work with a 415H chain. I have been short shafted! Maybe I can find a parts supplier for these, if not I have spare parts. Or maybe I will build a Go-Kart.
