My son is still using my old 02 660 Grizz and the only things that have been done to it besides oil, anti-freeze, and air filter maintenance is I have replaced both rear axles, and replaced the throttle cable and choke lever. Don't have a clue how many miles it has, the display has fogged over being in the sun. The other amazing thing is I put 29x12-12 Maxxis bighorn originals on it in about 04 and they are at about 50% now.
