Omega (went on to be Mec-eur) made some in the 80s. I got a used GP one recently to use with my autisa kit.

run it 58mm and take advantage of the extra cc's? or are you trying to do a bonkers 125?

Would it be possible to utilize eccentric crank pin facing inwards? Assuming that this setup needs "exotic" con rod and therefore custom made crankshaft.
