Couple a high rpm three phase motor to the crank shaft, magneto side is the easiest. Get a rectifier and a controller. Use the controller to start, rectifier for power generation. Not recommending it but it can be done.
How does this actually work, what do I need and what do I do to drill start it
I like mine, but I decided I wanted more low end grunt with the capability of a top end.
one side has a socket driver the other a hex that you drive with a power tool. Put it on the magneto nut and crank until it fires up. The tool freewheels so you don't risk stalling out the engine. There's also plain old bump starting by simply running and pushing the bike. I've done that before, and it works. Keeps you from carrying a drill.
I am hoping to be able to kick the pedal on my bike with the rear off the ground and have it start up.
