Hi Guys (re-posted here instead of Garage)
I have a 1980 CB750C I am rebuilding, and while I have the engine open I am curious if it's possible to increase the stroke by using the crankshaft from a cb900f engine. If so, are there any additional parts I would need to make that work? I am boring the cylinders from 62mm stock to 65mm so I can add a Wiseco 823cc piston set but I was curious if I can increase stroke this easily. I'm guessing it's not that simple and I would need longer cylinder sleeves or something of that nature, but I couldn't find a lot online about it.
thanks!
