That's a good assumption Tony. The hot Yamaha 4 stroke sled is their R-1 bike motor with carbs and a CVT.
I see nothing wrong with proposing 4 stroke alternatives-but there must be realistic expections in terms of cost and added weight.
We may end up with 850# or 900# min weight for all cars to make it fair for the 4-strokes.
