Hi there, I'm from Argentina (South America), I got a couple of years ago a 1981 ATC 110 (or something that looked like it once was an ATC) and spent a little fortune to get it as much as possible to oem condition. I have changed a LOT of pieces replacing them with new or NOS pieces when possible or just by good condition pieces found in ebay. I have sanded and powder coated the frame, fuel tank, fork, rims, hubs, crankcase covers, I also sanded and chrome all other metallic parts including the rear wheel axle, replaced all the bolts and nuts by stainless one, new Duro tyres, new aluminium handlebar, etc, etc. I'm just finishing the electric connections, and some other minor details, but I haven't yet run it.
So I find this forum so interesting and I hope to share information with others "ATC lovers" members.
