Need to find a motorcycle engine

[davehohoe]

Want to go fast so I need to find a motorcycle engine for my go-kart

Welcome to the forum. How fast do you think you want to go. The common industrial engines can be built to push a kart pretty fast. Also are a lot simpler
to mount and set up on a kart. Usually just bolt on.

Check out Copart, buy a wrecked bike. That'll keep you busy and off the drugs.
