For 4t's I aim for 13/1 flat out, and 14 on cruise, and 12/1 on 2t's flat out.
The gsxr is a little wheezy in std form, and seems to suffer form a weak 'signal' at the carbs making them tricky to tune as you want them.
I've gone pod filters on mine, and mine goes super rich at 12-14000rpm but makes 55 at 12000 on the same dyno.

A larger main air jet would sort that out if you were looking to lean it off at the top?
