Carb Sizes on 1S and 1R

Post by supastar »

Could someone please tell me why there is a massive jump in carb size from 28 mm on the 1S to 35 mm on the 1R?

because the S is for street use and the R for racing.

35's are better for high rev's, 28's are better low down and provide enough throughout the entire rev range.
My ultimate goal is to die young as late as possible !
