My good mate Jacko has an engine, 'box, mag, carb, tank etc from a BSA 'Roundtank'.
It's all in excellent condition, BUT! He needs a frame for it, (forks and hubs too, but frame is the important thing initially).
I know this ad is a longshot, but it's a shame if this didn't get built into a bike.
If anyone has any leads please PM me.
