Theres a guy not far from me that has a machine shop set up in his back yard.
I bought a crank cheap off eBay that he did for a customer that never got picked up.
He said he used to do lots and lots of Victa stuff when the motors were used on karts. He also made mention that another big drama with them was the crankcases were rarely square and parallel.
I suppose this is all stuff you need to get into if you want to double or triple the output of something thats rather 'rural' by design.
I could chase up his info if you want.
It would be considerably cheaper to just find another good used motor.
