Ok, I am totally confused whats going on and need help. about 4-5 years ago I noticed that my 14 tooth sprocket was diggin into the front of the swingarm and the chain was wearing down the bottom of the swinger at about a 30 degree angle on the bottom half of the swinger. General consensus was that my frame was tweaked and the motor had shifted in the frame due to 10+ years of hard MX use, cracking, welding, and etc or my output shaft bearings were worn. Fast foward to today, I am detailing the R and notice that again the chain is rubbing on the bottom of the swinger at about a 30 degree angle. It looks like its worn almost a 1/4" through the swinger.

Anyone have any ideas? I have a different frame and swingarm than previous, rebuilt the motor with new bearings and output shaft. I am totally lost. will try to take pics tommorrow during the day
