    My GSXR recently had similar symptoms above 5500RPM. Turned out that the exhaust valve servo thing (SET valve in Suzuki speak) wasn't opening fully. The plug had come loose.

    Otherwise, fuel tank breather?

    Read my earlier post - fuel cap breather. Should not explode in any manner when you open the cap. Unless the bike is on fire of course - then it should go bang.

    A blocked fuel tank breather stops the engines ability to suck fuel at the rate required at higher revs - it will starve the engine so it will not rev. In order for the fuel to be drawn out quickly it needs air to be drawn into the tank at the same rate. Through the breather.

    Modern day fuel injection systems are quiet complex and a few Engine Management Units have built in safeguards which can limit or restrict a engine in a the event of a sensor failure. Can often be described as a "Limp Mode" which deliberately makes the bikes fueling mixture rich and could possibly modify the maximum RPM.

    Long shot, but if clearing the breather doesn't work then have the Narrowband o2 sensor checked (if one is fitted). Get a elminator for it.

    Breathers were blocked, also was a kink in fuel pump. So all good and fixed now for 1.5 hours labour
