50cc quad bike engine

[damo1]

I need a 50cc four stroke quad bike engine any of
you guys know where to get one from.

It's the one that looks like a postie bike engine.

Its an electric start, full auto jobbie.

I'm happy to buy new if you can supply the right one
or even just close that i can mod to fit.

You know what i'm open to offers of anything at this stage.
But it is for my 3yr old boy so be realistic.

Cheers Damo
