It turns out that the fifth sprocket I ordered actually fit. I ordered a couple from a few different dealerships only to find out a 5-10 days later that it was out of stock and no longer available. It must take a long time to walk back to the shelf and look... Must be a BIG warehouse. I am working on the motor mount today and the front sprocket should be in today as well. I have the controller and contactor installed and most of the low voltage wiring. Also the DC-DC converter came in which will get me 12VDC out with input of 70-150VDC input. I installed that last night. I am missing headlight and front signal lights and associated wiring and batteries and charger. That is about all. I suppose I could pull batteries out of every car and motorcycle I own and string them all in series and make the motor spin. It would be a lot of work, but is sorta tempting.
