Bike acceleration problem

So I have a 05 CBR 600RR. The bike starts up fine and rides fine. The problem exist when I give it throttle and when the RPM reaches to 5-6K the bike boggles and won't past 6-7K RPM. The bike at this RPM doesn't feel like it accelerates. What can't be the problem? It will never pass 6K RPM.

Have you checked the fuel pump? Low pressure and flow rate will cause this.

Done any work on it recently?

What is the normal pressure on the fuel pump? How do I check the pressure? and how do I know if the fuel pump is bad?

50PSI, you use a specific pressure gauge to test it - probably something you just want to take to a mechanic for them to do as the gauges aren't all that cheap.

Flow rate is 167ml / minute, you just disconnect the fuel line and put the end into a graduated container and wire the pump on and let it run one minute, measure the volume that comes out and your done.

You will know if its bad cause it will be below 50PSI or less than 167ml / minute
