I want more torque and hill climbing ability out of my 85 200x. Im havin a hell of a time finding a bigger tooth rear sprocket for it. Is the an adapter or different hub for the axle to run different bolt pattern sprockets. I did find a 41 tooth but dont feel like thats a big enough change from 40. Motor is strong and dg piped and k&n filtered. Just always have to enter a hill screamin . And if u let off for a root or rock and get back in the gas she will fall. Thanks guys.
