Good EFI throttle size for KZ750?

Hey guys,

Really keen on the EFI route for my KZ750 build. Would you say 36mm ITB's are a fair size for a 750 with 810 piston kit?

There seems to be a whole range of modern 600cc itb's available that can be spaced in various ways. I'm considering FZ6 ones which are pretty inexpensive. GSR600 is another good looking option, and then R6 is flooding ebay. zx7r itb's are anoter option with their 75mm spacing.

I went with the FZ6 yamaha 36mm ITB's. The stock carbs are 34mm. Spacing is 73mm on the FZ6. Looks like the KZ is 75mm (zx636 would have been a better fit at 75mm but most of the sets on ebay are incomplete)

Will post further detail in my build thread.
