New sprockets

stock would be a 13 tooth front and a 40 tooth rear. You can put a 14 tooth on the front and a 42, 38, and 36 i beleive on the rear. Up a tooth in front gives more top speed but less bottom end power. Going down in the back does the same. One tooth change in the front is equivalent to 3 teeth change in the rear. Now its your choice as to what sizes you wanna run. Most run 13/40 or 14/40. I run 14/40 because i need that little extra on top for some of my trails.
