Help Understanding Ski

I bought a superjet recently and I am having trouble understanding it. the guy I bought it from, didn't kjnow much about it but he told me it was a 760 bottom end and a 701 top. Can someone explain where the bottom came from?

I am trying to find a rebuild kit for the carbs and see a 64X on the side of the carb. I think this means its a 44mm, correct? Any Mikuni rebuild kit for 4 screws will work?
 
Yes, get a genuine Mikuni rebuild kit for them and accept no less.

Watcon, JetManiac are both good places to buy. Rdrttoy sells just the parts needed so its less than buying the full kit.
