I got one of these 86 G models. Got the DG exhaust .Still runs and rides regularly at a mx track. If you're ever coming through KY stop by and get it. People keep trying to beat me down on the price and id rather just see it go to somebody who can use it.
I used RMATVMC and Motosport for many of the OEM bearings and gaskets. Still available parts believe it or not. What I couldn't find available there, I sourced ebay quite a bit.
