Hi guys,anybody have idea whats wrong ?On neutral engine rews easy on top rpms and easy stay without trouble on 8 9 thousand rpm,but in gear on run start idling and shooting in exhaust when I try go over 55 - 6 thousand rpm.I've got on new ignition coils new spark plugs and new caps.So I have not clue whats wrong.

airbox or pod filters?  on standard jetting and airbox off it would do something like that

carburetor is 36mm from Gsxr

Fuel flow problems perhaps, it's easy to link the pipes when refitting the tank, maybe the tank breather

Doesn't sound like ignition from what you say, so carbs it probably is ......

Are all jet sizes on your carbs much the same as a  GSXR1100K/L ? - this should be fairly close, enough to run well enough to adjust if needed anyway. If you're using GSXR750 carbs and the needle from that, the 1127 engine may need a richer needle.  Is the float height set correctly on all carbs ? - this can affect all circuits.

When ridden and it halts at 5k revs, does it buck around like it's running out of fuel, or fall flat on it's face ? - lean or rich - from this you can work out what to do.

Good you found the problem. Was jetted too rich - maybe best to fit a good after-market filter and maybe jet down at some stage ? - no air filter will make the engine wear quickly.
