Blackmagic21 would you be interested in buying a black magic .21 and the pipe? and if you were what would you offer for it? I think the bearings need replaced and there is still alot of pinch in the motor but not the mechanical pinch. You can roll it over with your finger when the glow plug, pipe, and carb is on it with some force. Meaning it doesn't get stuck at the top. But any who, what do you honestly think it is worth.
