Karl:

You cannot increase the stroke solely by using longer rods. The crank,
and crank alone, determines the stroke. After stroking the crank, they
had to change deck height on the pistons so they wouldn't have to
change the heads and cylinder lengths.

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.

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.
