does a 92-01 crank also work in 86-91 cr250 motor?

Also what the differnt between a 74 crank and 74 big journal crank that ESR use to make.

Also does anyone convert stock 72mm into 74mm or 76mm cranks

Thanks
Robert

Rts make there own stroker cranks out of brand new honda cranks, so I beleive that they could do a used one for a bit more,

Yes I believe that Wes told me that the 92-01 cranks will fit in the black style motors...which is the 88-91 motors. Not sure about other years.

Large journal cranks have a bigger pin in them, which use a Kawasaki style rod.

Also RTS does turn stock steel cranks into a stroker for around $200. Sometimes when you press the crank rod pin out it will break the welds in bushing that is welded in. And the tinning can fly off as well. I reccomend a billet. But the stock styles are an alternative.

Dont quote me 100% on my information, im trying to go off memory from what Wes has told me. He would be the man to talk to about this. Hope I helped!
