Hi - I just bought a KDX200 C2 (87) which I am going to renovate for a friend. It was pretty rough - like silver paint sprayed over thick sand on the shock. A front m/guard where the rear one should have been. Every nut and bolt different (and rusted). The rear shock compresses then stays there. The list of crimes goes on. Anyway it's now in bits awaiting full sandblast, nickel plating, powder coating and rebuild. Can't wait. I'm trying to do everything on a small budget. I wondered if anyone had any pointers. Any owner's rebuilt bottom ends on the aircooled KDX's? Is it straight forward or a major? Does anyone have a good condition rear m/guard and light 86-88 and a very good condition front pipe (stock or performance) that they want to sell? I'm also trying to track down a manual. Would an 84/85 KX125 shock fit? I've also seen rear disc conversions - would the caliper off an 85 KX250 fit onto the swingarm lug? Thanks for any help.
