Hey guys, I’ve been a long time lurker around here but just joined to post my first build. I’ve always loved seeing you alls build threads and it’s actually what got me back into the sport after about 10 years away while in high school and college. I picked up a couple bike in the last year and none of them fit what I wanted so I went on the search for what I thought I wanted. A couple weeks later I came home with a roller of a KTM 200SX and styrofoam coolers full of parts. This is what we had to start with.
It all appeared to be there and didn’t seem to have and major abuse over the time, but the top end was completely destroyed. It looked like the piston had broke a ring and lodged it in a transformer port before coming to an abrupt halt. Cylinder has about. 1/4” deep gouge, the powervalve flap was damaged and of course the head had taken a beating from loose debris bouncing around inside the engine for some amount of time. The good news was that the crank and rod bearings were as tight as could be. Other than this and some broken plastics the rest of the bike looked pretty good for a base build, so after the first night this is what we were left with.
