First place to start!!!
I just got finished working on a friends bike that did what you are talking about....It was a stock 95 and it didnt run worth a crap. I tried everything until I found this site and removed the valve under the tank...
Go to the tech tips and look at the float bowl mod...
After I did this mod I used my stock 95 ZX6R needles and dynojet 150 main jets all that I had left over from jetting my ZX6R. The bike ran so much better it scared the **** out of me!!
If I were you I would do the mod listed above and call Factory Pro for a jet kit!! Tell them what all is done to your bike and tell them that you did this mod which seams to be widely known in the ZX7 community and they should be able to set you up with the right kit for you.
Trust me it Helped my friends bike a ton!!!!!!
