Well than your Looking at a couple hundred bucks to fix that. I have bought and sold enough bikes to know that odds and ends add up. If your getting it for 500 I would expect to spend another 4 or 5 hundred to get it where you want it. This is without seeing it of course. So you would have around 1000 bucks in a blaster with a fresh top end and in decent shape. I say go for it. Any mods would be a bonus at this point.
