What engine could fit in a dog go cart 6.5hp YERFs? I'm looking for a more powerful engine to put in my go-cart, any engine over 6.5 hp and fits with an ease that is good.
Just about any motorcycle engine. You'll probably do good with a dirtbike engine. Try a 250cc 4 stroke engine ... Believe me its going to go fast, you just gotta know how to pass.
