Pro 785 Rod Interchangability

[milesengineer]

I have been looking for hours on this subject and cant find any absolute answers. Is there another Fuji engine that uses the same rod? From what I can find is the crank is specific to the 785 but no one can tell me about the rods.

Any help is appreciated..


Thanks

I was under the impression the cranks were the same, but the 785 rods were longer.

it is possible you are correct. i was on the other site and that was what i got from it. they said that the stroke was different, wiseco says the same thing so that is why i figured the crank was different..

technically the crank is different. It uses longer rods, so it's different from another Fuji, meaning not interchangeable.

but if i get a 750 crank and put 785 rods on it would it be the same as a 785 crank?

longer rods? IF the 785 stroke is 3mm more than a 780...then the rods would have to be shorter ..to use the same height cylinder..

I don't want to say yes and it be wrong, so I'll let the real Polaris Guru's chime in.

Here you go bro. http://www.atlanticpowersports.com/n...anufacturer=14 Pro is 69.7mmx68mm stroke. A 780 is 71.3mmx65mm stroke.
