got the engine back together tonight with the new big bore cylinder and piston. It’s now 149cc. I took it for a little ride up to the shops and everyone was looking at it. Still some work to do with re-jetting the carburettor, I went up two sizes on the main jet and raised the needle to maximum and now it’s way too rich. Better too rich than lean, but I’ll sort it out tomorrow. Still need to finish the front mudguard and modify the instrument bracket to hold a tachometer. My Christmas present from ange is a MIg welder so I can do those other little jobs over the Christmas holidays.
