Hi Guy,
The bore on the 750 and the 850 is the same (83 mm), yet diffent pistons
are used. The stroke is increased between the 750 and the 850 (from 70
to 78 mm), but was done so by a change to the journal height on the
crankshaft.
So, Guzzi decided to change three more expensive parts (2 pistons and 1
crankshaft) instead of two less expensive parts (2 connecting rods) just
to increase the stroke.

Hi, I'm pretty much a newbie on this list.... Anyway, I don't understand somebody's comment: "You think it would have been cheaper to just change the rods rather than the crank and pistons". Thanx, -Guy- 71 Ambo "the 750 & 850 rods were the same. The stoke difference was in the position of the crank journal and the wrist pin height on the piston. I don't know why gauzy did it like this. You think it would have been cheaper to just change the rods rather than the crank and pistons. Maybe they had a bunch of rods they needed to get rid of."

I believe that the Eldo con rods are not interchangeable because the stroke was increased to 78 (bore remained at 83). I don't believe there are any differences in the crankshaft that would affect the con rods. I'm sure someone will correct me if I'm mistaken. Good luck. andy hill wrote:
