is there a way to tighten the sprocket hub and brake rotor on the stock axle. mine are starting to get loose and i don't know a whole lot about the axle and bearing carriers and stuff. any help would be appreciated.

 

Grim - it sounds like your axle nuts may be loose if you have play in the sprocket and rotor hubs. Try to tighten it up a bit and see if that helps out. Also, check the condition of your bearings in the carrier. It would be best to lift your quad up and see if you have any play in them.
