Searching parts for >720cc

Hi,

I´m searching parts to do bigger engine to my VM20 -42.
Parts I would need are linerless cylinder and M21 crank or flywheels. Also aluminium head would be nice.

I recently read an article on which one special 725cc sprinter was done by removing liner and then just boring it. Could one estimate it to be sensible solution, I think base cylinder cast is quite soft...

Best regards,

Paavo, Finland

Re: Searching parts for >720cc

Hi Paavo..I wouldn't recommend using a linered cylinder with the liner removed..as you suggested it is highly likely the base material of the cylinder is not specified correctly to run a piston and rings in.
The Sprinter you mentioned would only have run for very short periods and in total for very few miles I suspect..Ian
