Need help to get started

[Valkyrie2001]

Hello I need some help to get started. I have some questions that maybe you guys can help me answer and give me some advice.

I have a Sun recumbent trike that I want to put a motor on. I am a recent right leg below the knee amputee. I only mention this because I want a motor with electric start.
To start with I would like to get a 6 or 7 horsepower four stroke engine with electric start 12 volt.

My next question concerns what type of clutch and chain size and sprocket for the wheel. I am confused about what to buy I think good quality would fill the bill. I am guessing the rear sprocket would bolt onto the spokes of the wheel. Also lastly besides the engine would there be a place that sells what I need as a One-Stop shop. I know there's other parts to buy and there are a couple of companies that sell kits but no electric start. So any advice you all can give me would be most appreciated, thanks.

A 6 or 7hp should get you to about 50mph on that thing. Is there some reason you need so much horsepower? My other thought is if you live in a state that it would be legal in.

Does a smaller engine have an electric start?

There a bunch of 50cc electric start engines, and this one may be good? Search ebay for electric start minibike engine: https://www.ebay.com/itm/125cc-4-st...ash=item41d8d780ee:g:kl0AAOSwA3dYYJ8E&vxp=mtr

most folks with three wheels go with simple electric motor and carry batteries in back

yours seems to have little in the way of solid mount points for gas motor
