The Medcine Man
I don't believe you know what you are talking about maybe on an wideopen outdoor circuit Carmicheal busted 4 stroke as ON a 2 stroke and a 2 stroke of the same cc as a 4 stroke will beat the ass of a 4 stroke same reason why in a dragrace it would damn near take more than 650cc to stay with a 500 2 stroke.He also raced a CRF450 for a year or 2 before he left honda. He is the best and could win on anything but every interview I have ever seen him in he has said that the 4 stroke has way to much of an advantage of two strokes to not ride one against two strokes.
But on that note I have had alot of 4 strokes but im switching back to a 250 2-stroke because in any amatuer races it can be ridden in the lites class against 250 4-strokes and thats a huge advantage.
But to tell all truth dirt bikes have such a great power to weight ratio that it's mostly the rider. Carmicheal was the fastest I had ever seen on a bike on a 2 stroke. Maybe with the exception of Mike Larrocco that guy was a phucking animal on a 500 back when they used to have the class in national MX!
