Super Jet SJ 650-701 Swap question?

[Kbauer8]

I have a 1990 SuperJet- very fast and revs to the moon

-650 bottom end
-cylinder ported to 80mm
-dales bad attitude ignition
Rev limiter is still in there
-Coffman sizzler exhaust pipe
-stock waterbox

I have a 61x 701 from a vxr pro. Single carb. I rebuilt the engine, carb.

Could the 701 be put in there using the 650 electronics with the dales ignition and Coffman pipe?

Would it be worth it?

Yes, but how much better is it going to run?

Thats kind of my question. I don’t want to go through the work of changing it if it’s not worth it.

Just leave that ski alone. That 650 was damn close to the speed of my 701.

Ya, the last thing I want to do is screw it up.
Was just curious.
