    Guys,

    Does anybody on here know where id get a new piston for one of these. The previous owner took the barrel off and then decided to push the bike around in gear and cracked the piston.

    I've no idea. Not much help that, but thought I'd just say that I love the bike!

    Presumably it is not going to be your daily commuter.

    can you get the dimensions of the piston, ie piston diameter, gudeon pin diameter, distance from centre of pin to piston crown, i presume its a 2 stroke engine

    ROFL, no definitely not, it had a top speed of 65mph and im sure that was with a lightweight Italian riding it not a 17st Paddy on it!

    Yeah have all of these as i have now stripped the engine completely and need a new/repaired piston to finish it off.

    Do you know somebody who could remanufacture one?

    Manufacture is possible, but I have found in the past that lots of diffetent bikes are designed to take the same piston, so your piston might possibly be the same as a 50cc moped or even a 50cc motorcross bike. Post the dimensions and I will have a root around to see what info I can come up with if you like.

    Yeah it sure is, my one has loads of history behind it. It was rode by the First Woman Maeve Mulvany to race competetively on the Irish Road Racing scene and the bike was raced at the North West & IOM TT.

    This is project number 2 as the CB400/4 is nearly complete.
