W2000 bhp

Post by Dekave294 »

Hi all, what are the detail differences between the 27 and 33 bhp versions of the W2000 engine, carburation etc?
Many thanks in anticipation, Ian

In my limited knowledge of the DKW/ Hercules 294cc rotary, the compression ratio has never changed from 7.5 to one.
Later engines (Black tank bikes), had a mikuni pump to provide 2 stroke oil instead of the pre-mix of the 'red tank' machines.
I don't think the yellow tank prototypes were much different.
Would love to hear from someone more knowledgeable. Especially if you know of any early engines with an offset higher compression combustion chamber.
