Well maybe for now I should borrow your chain and sprockets. My XR has developed a case of the tweeker teeth as well. Seems like a ravenous plague. Once one tooth goes, they all start falling out! Its purdy but not as bad as yours was yet, another ride should do it.
I just changed the sprockets on the DR today. It was even worse that when I changed the XR. It looked like a dull circular saw blade.
What is this, a Price family problem? Not replacing chains/sprockets?
Seriously though Aaron, you'll be back in one piece real soon, keep your chin up!
