yes they changed them to 14 front when the added reverse... i have had both and have worked on countless numbers of both.... they also changed the splines on he output shaft ... and the older sprockets wont fit the newer 1's

I rode arount RAC today with my 13/38 combo. It produces a lot of twisting power. I had to adjust the drive chain on the trail as it stretched. Too much power in fact it would break the rear tires loose on the trails. 22" rear tires coming soon to bring my top speed up. I can however crawl through the trails at walking speed without touching the clutch.

With 20" tires in the rear a great combo is 14/38

With 22" tires 13/38

Dont enlarge the rear sprocket as you would lose ground clearance

If ya want real gains do a stroke or bore upgrade and a cam. Those plus the intake slip on and dynokit will.really make your quad fly.

If you wanna play you gotta $$$$$

Put sugar in his gas tank. I think that going down a tooth will help you come out of the hole quicker. Then adding the slipon filter etc will give you more horsepower througout the powerband. Will it be enough to warrant a rev limiter remap im not sure

Send CK a pm. He drag races atvs
