My chain was worn out and I hit a rock and bent my chain guide, the one in front of the rear sprocket. I purchased a moose guide and block kit, Regina o-ring gold chain, and 15 48 Renthal sprockets. I installed everything and the tab was bent for the guide. I bent it back until chain went in center of guide. went for a long ride and got this. It is wearing everyother tooth on rear sprocket,stange. and wearing evenly on both side of new chain guide. The chain is also rubbing on tire and subframe. I could understand if somthing was bent it would wear out one side of sprocket and one side of new guide. I do not know where to start. bent hub, motor bolts are tight and do not look like shifted. do not know where to start. I guess i will get a straight edge. Unless somone has had this problem. Thanks for any help.
