Crankshaft

they should all fit, ma09,ma10 and ma12 use the same block, it will just be the bore and stroke that are different, probably not even the bore just the stroke

Bore is cylinder width :)
Short answer is MA10 crank is the same
MA12 cranks has ~50mm longer throw
Reason MA09 is a smaller capacity is it has a 2mm smaller bore and different piston shape iirc

oranje
thankyou for your replies. I will use a second one i found in my spare parts. Hope in one to two weeks can upload photos of the progress. Thanks again
 
so that means the remaining questions is...does anyone know if the ma12 crank fits in the ma09 block without fouling :) stroked super turbo, would give about 1.1l with the ST cylinders
