Shovel Bore/Stroke Question : V-Twin Forum: Harley Davidson Forums

Mercury · 05-10-2011, 08:51 PM

Guy at work has a Shovelhead motor. Says it has a 4 5/8 stroke crank. He wants to know what bores will make what displacement, and what is the largest bore he can go to.

I told him I didn't know... but knew where to ask the question. Anyone?

3 5/8 bore x 4 5/8 stroke = 96 cid
