Re: Electric Start
They work quite well. I've had several scooter choppers with that style engine. The bigest issue I found was the low quality batteries available in the small size needed to fit those choppers. If you get an year from one, you're doing good.
The starter is built into the recoil assembly and also functions as a generator on some, depending which exact engine you get.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
