Hi: fmints thanks for the complments... yes i have the 13 tooth off the trans,amd i still have the 16 hp i switched to the splined axles because the hole in the axle on stock hustlers will crack after time if you ride it alot i had one crack completly and when switching out to splined i found another with a small fracture in it also the stock axle sleave can get rusted and have to be cut off it happened to me twice with the splined axle loosen the set screw and one or two wacks with a hammer and its loose. Also changing your roller chain adjusters to the max one is a lot better and easier to adjust ( the Rollers suck)
