Re:Idebtify this CMB part

Allen is right but which one is it?? I'd say .65 How about you??

If any one has a .65 or .85 GranPrix could you give me some dimensions so that I can compare this one eg bolt hole span, length etc.. Also any idea as to the age of these engines I have never run CMB.. Thanks Tony J

Looking at the ruler I'd say it looks more like the old .90 GP backplate. Check the Needle roller. If its 12mm bore then its the .90 backplate.

Dave its 12mm Thanks very much for your help. What vintage are these motors.. TJ

Tony,

Mid 1990s for that engine. Last of the silver 90s before the EVO Black engines (gold heads) were released.

EMS Racing yes I still have one or two of those

 

[Dave Marles]

I agree, its from the GP 90 zimmerman disc engine. This engine was preceeded by the drum valve engine and followed by the EVO engine.
