i was washing off some of the gunk on the rearend of the quad i just got and noticed the only thing holdning the rotor in place was the caliper. it just kind of wobbles there. from the pics you can see there used to be what looks like a seal or dust cover there, what am i missing? aslo the sproket seems alil sloppy too on the axel, any fixes or suggestions? and for fun i tossed in a pic of the p/o welding job on the chain roller lol. i told the guy he needs to take all his tools and toss them in the river, never to touch a machine of any sort again lol. i got this thing for $25 so i cant complaine too much, but damn!
