The stock track on my 98 mxz 670 has one or two tearouts. The tear length on each is about one inch and does not go to the edge of the track and is from the stud hole moving out. Should I be concerned and start looking for a new/used track? Would putting a new stud in and cranking down the nut to the backer stabilize the tear? I am pretty sure that one of the holes was present before last season. Have put on 1,500 miles since.
