NOTHING! It's just barely broken in. Evo bottom ends are solid, if the bike looks perfect, the owner has taken care of it. Might need to freshen up the top end but thats $3-400. If you like it and the price is right, BUY IT!! If it's really nice, maybe 12k but that would be absolute tops for a mint 12 year old evo in the dead of winter but, probably closer to $9500 is where I would expect to see tha price on it this time of year and with the milage. There's unfortunately a big glut of used bikes on the market so make sure you get what you want, alot of GREAT deals to be had out there!
