Something I've always wondered about; sprocket sizes. Why do low horsepower, lower RPM, low-speed engines need to run such big sprockets and drivers?
I've done some 2 cycle induro racing's
and I've never used anything larger than a 14 tooth Drive sprocket, with a 4- 1 ratio. The KT100 can easily turn 14,000 RPM with speeds around 100 miles per hour. I ran one race, that I won by a very large large margin, on a track with a very very long straight, in the McCullough 101 class, with a 10/53 ratio set-up. It makes me wonder why that type of thinking wouldn't work with a 4 cycle. It's something to think about.
