FWIW, a Kaw Brute Force 750 is a single pin crank like a Harley. They are right torquey. Makes about 60 HP. Has a cute idle. I'm running a stock muffler due to using this thing where only golf carts are allowed.
I'm using BF 650 heads which up the compression from 8.8 into the mid 9s.
That's the reason for the jet kit. V twin Prairie and Brute force engines are like small block Chevy's...parts are interchangeable to a high degree. One better understand the pitfalls of such mixing of parts.
As stated, having tried the "cart" rear axle on a previous toy...I wanted a big, solid rear end in this cart. It's a little too long, and nothing to do about it other than cover it up.
So I'm gonna have a little pulling truck bed in the rear. It'll like a small pickup.
