#wheezathebeeza - Opening a can of worms up...

My last post I said that I though the plates on the flywheel had come loose. I was right. The right hand one spins. I have removed the head, barrel and piston.

Measured the piston and it looks like this bike is now at 180cc. I assume this was re-bored after the crack in the fin was welded/brazed and the bore would have distorted from the heat.
