Right now I have the stock tires on my 300. Soon im going to be gettin a set of razrs front and rear. The stock rear tire on a 300 is 22inchs tall and im gonna get 20inch razrs for it. Ive heard that going from 22inches to 20inchs is a 10% ratio change. I have a 13t front sprocket on now, which is the stock number of teeth. Ive heard that going to a 14t front sprocket is 6% or 7% ratio change. If this is all true, what can I do to make up for the rest of the ratio change, so i wont be loosing any bottom end or top end power? Would I have to go down a tooth or two on the rear sprocket? Thanx for help guys

I wouldn't worry about 4%, you won't even notice it. But If you want to fix you have knock it down 1t in the back.

Ok, so going down one tooth in the back is around 4% or something like that? Your probably right, its probably not that noticable. One time my friend and I switched tires, he has a 400. And you could deffinatly tell the difference, i had stock gearing, and you could tell it lost some top end.
