axle with a keyway and a key and a set screw. i think thats everything, but if u cant find a 520 rear sprocket try changing the front sprocket on the engine.

If your able to do the machine work yourself, the least expensive option would probably be to adapt a used/smaller diamitor #520 motorcycle sprocket and hub over to your axles size.

Heres some #520 rear sprockets made for shifter karts: http://www.gokartgalaxy.com/shifter_kart_&_quarter_midget_sprockets_for_3.htm


You'd still need a kart style sprocket hub thats made to fit your axles diamitor: http://www.google.com/products?sour...a=X&oi=product_result_group&ct=title&resnum=6

I did some research and found some guys that recommend first changing the engine sprocket over to the #428 size for your situation, and then buying the matching chain and rear sprocket. I'm not sure why but you should probably reserch this link too: http://www.google.com/search?source...1T4DMUS_enUS221US222&q=Shifter+kart+sprockets
