I swaped the swingarm for one off a 13'. ($30 w/shipping - ebay)
I rubbed a lumber crayon in the crack to make it show. Starts at the weld for the rear footpeg mount and goes up and around the top, and the same around the bottom. The backside was all that was holding!
Glad I spotted and fixed it BEFORE my trip to the KSL over the 4th. Don't want to think about it breaking 700 miles from home, or 7 miles either!
As compared to most other major parts it was a pretty painless fix.
