Hi All,

I have a ZXR250 B model and I was wondering if the C model has the same block as the C model, I know the bores are different but if the C model block fits, then I can make a hybrid out of the 2 and that way get the parts with no quibbles.

Also, if the blocks are the same and the head from the B model fits, valve clearance and all that, does anybody think it's doable?

Anyone know this? the thing is, I cannot find any info on the B model to see if they match, has anyone ever tried this?

Cheers!
