I have read some where that the capacity difference between the 750 & 850
was in the stroke, but Guzzi did it backwards, instead of changing the
length of the con-rod, they changed the journal height on the crank and also
changed the wrist pin height on the piston. The 750 & 850 pistons have the
same bore but looking at them the wrist pins are in different locations.
But from what I have read the rods are the same between the 2 motors

The 5spd will bolt up but you will have to change the shifting linkage as
the spline shafts between the 4 & 5 spd are different lengths. The clutch
cable is also on the other side on the 5spd.

Hi Andy,

I believe that the con rods for the V700 and Ambo are
interchangeable...least wise they have the same stroke (70) and only
differ in the bore (80 vs. 83). 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.
