fzr crankshafts

hi guys! i'm rebuilding an old '86 FZR1000, (genesis?) the crank looks a bit minging so i set about looking for one,

there's a few 750 ones on ebay, but my manual says the stroke is different between the 750 and the 1000.

- i just thought the bore was bigger?

does anyone have any enlightenment on the subject? have you tried interchanging them etc?

in short... will a 750 crank fit into a 1000? i'd have said not, but some i have spoken to say "they're all the bloody same!"

"shame on you"

"get off my garden"

"stop it you dirty b£$ta%d!"

and other things..

helpy-helpy-verry happy.
