I am doing a very similar project using a 36 volt motor from an electric go-kart. My problem is that the motor has a sprocket on the shaft and it doesn't want to come off. Also, the shaft is 5/8" diameter and the original dual pulleys are for a 1" shaft. I am trying to figure out how I can mate these things, or should I do some engineering to make use of the sprocket? i.e.: mod the system to accept a chain drive?

BTW, congratulations on your test run! I'm looking forward to getting mine ready for its first ride as an electric!

I tried an experiment... I used one of those tools that you use to flange a copper pipe, cos it's basically the same action as a gear puller. Miracle of miracles, it worked! I successfully pulled the sprocket without having to destroy it! Too bad I have to go out of town for two days, cos I could have worked on my project instead. Well, there is always the weekend...
