I noticed the chain slider on my 2003 was badly worn. So I ordered a new one and removed the old chain slider. After removing the chain slider, I noticed grooves in the under side of the swing arm. It is as though a loose chain in the past has whipped up into the swingarm and worn grooves into it.
Anyone familiar with this? Cause for alarm? Time to replace the swingarm?
Anyone have a used swingarm in average (undamaged) shape for sale?
Sorry, no picture.
