OK, the new build is an abandoned mini bike, but this one has a rear swing arm and shocks and springs. I'll make more post as the progress comes along.
To start with, to be able to clock my TAV at a reasonable position I had to chop off a piece of the head, not really needed and doesn't interfere with anything.
I have all the parts except for the seat, which I make. I'll see when I get to that point. I'm going to strip and paint the frame now that I have the motor fitting.
