B204 piston/conrod dimensions

[hansUS2]

Hello from Seattle,

I am looking for engine specs for the B204 engine. I know bore and stroke are the same as B202. What about piston compression height -- same 40mm as B202?

Same 134mm rod length?

Big end diameter and width?

Piston weight?

I can get B204 parts cheaply, and was thinking I'd put b204 piston/rods in my next B202 re-build if they fit AND are lighter.

Thanks...

Rod is 153mm
Comp. height is 40.5mm
