[peter71]

can anyone tell me if a 1200 crankshaft is the same as a 1300 crank shaft???

[Damo]

No i dont think so mate someone will be able to confirm mind.

[garyc]

no on the carb version, however the 1.2i crank is the same stroke but has a different oil pump drive.

[Royston]

No 1.3 has longer stroke

no on the carb version, however the 1.2i crank is the same stroke but has a different oil pump drive. if i use the 12i oil pump would it work?

[garyc]

I think so, I've never done it.

It does work 1.2 spi crank with the later pump drive on has the same throw as a 1300 crank.

1200 carb crank is 63mm stroke.

That's short.

That's just right for lots of revs.
And it's on the list of projects.
