I could probably spend a lot more money on it, as is probably typical with older machines, but I'm not going to get too crazy. I think it could probably use some front gear work as it clunks a little bit at slow speeds when turning sharp, but it doesn't make that noise when riding, only when turning real sharp going slow.
But, like I said, I'm not going to start tearing it down just for the sake of tearing it down, and I also don't intend to take it on 20 mile rides or bury it in water and mud.
Just for grins, I put it up on Craigslist several weeks ago for $2000 just to see what kind of hits I would get, and someone immediately offered me $1500 site unseen. I pulled the ad down, but figure those machines are sort of in high demand if I ever wanted to sell.
