seems like it smokes a bit so im hoping new rings. also it seems the people i bought it from rode it forever with the rear brake caliper holder just rubbing against the disk so its all chewed up. as well as what seems the left axle is longer than the right. dont know if it was set up for a track at one point or not but it pulls hard to the left. looks like i have a new project on my hands but this one is worth putting some real money into. is ebay the usual for finding all the good parts?
