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?

legalish 125 i think, mind you 58mm and packers might work

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

Ive got a 54mm stroke crank from my old Group 3 150,it was getting tired so had a new bearing and rod fitted but never used after that if anyone wants one
