I've been following this exact thread.Jim the thread below has some good info, cannonball has built a lot of different types of bikes over the years, I would rely on his findings.
Yeah.You'll hear a lot of opinions on the engine and the frame, I have had good luck with my aluminum frame and 48cc engines. My first bike which I still have is almost 9 years old with no frame problems. Cannonball rides along the coast where it gets very hot, he hasn't posted anything about his giving problems.
there are spossed to be pins in 2 stoke pistons, yes?That's too scary too contemplate.
Years ago. Holed a piston in a Zundapp. Couldn't find no Zundapp piston but a Yamaha had the same dimensions. Except for the locating pins. It fired up for about half a second when a ring snagged a port and chunked the cylinder.
End of Zundapp.
