Z2 Block

I have a Z2 engine, at least the casings are Z2 marked. However the capacity mark on the block is 903. Anyone know if Z2s had a specific 750 mark or did they use the same casing & just machine it differently?

sounds like someone has built a 900 in to the 750 crankcases,750 crank has a shorter stroke 58mm the 900 66mm,so just fitting the barrels of the bigger engine wouldnt work

Thanks. Looks like I have the bits to replace the broken fin parts on my bike.

Jon, it coulds have had a Z1-900 crank-shaft fitted. Which would make it work, your Z2 motor work as a 900cc.
