Never started a thread before so I really had no idea what was going to happen. I'm going to start by facing off the front and rear of the crankcase. This will provide a smooth machined surface to mount your motor mount and hall effect switch to. Your going to need a small engine lathe and some fixtures to be able to do this. I have a Auto-Cad drawing of all the parts that your going to need and I'll be happy to send anyone a copy of it for free. I'm not trying to make any money from this. This drawing will open in Draftsight or Auto-Cad. [email protected]
