I have an extremely clean and bone stock 09 limited edition cbr (blue and white) that runs excellent for a days worth of riding, and will ride in hot, cold or anywhere. Runs excellent up until after a day of riding, it will shut off at a light. Trying to start it back up proves difficult until you prime it two times with the killswitch with gas. It will fire up then die again later, and the more you try to keep it running, the worse it runs. It will fire up and idle at 1500, then die to 1000, and when you give it gas it boggs up or will rapidly go up, or rapidly decrease. Riding it one day to get home, it was drving at 7000 rpm then rapidly went to 5000, then back to 7000 multiple times, felt horrible.
i parked it for two hours then rode again with no issues, and rode it for another 4 hours until putting it away. Its done this exact thing before again and i have no clue whats going on or what to fix

Hi, looks like your losing the primary and secondary injectors at the same time which could be an electrical connection fault ,or even a fuel pump fault, as I don't think its the injectors themselves have a look first at the fuel pump and connections especially the Green wire if its loose into the connector at the fuel pump

 

I will check, is there any way to test fuel pump with multimeter? is there any way to test the primaries and secondaries? I will check the green wire.

 

Hi if its not the connection, could be filter blocked in side, are there any faults showing, Check here for your manual

is the filter inside the fuel pump? thank you

 

Yes, its more of a wire wool looking thing, but try all the external could be faults first, injectors in my opinion are ok, but wiring always seems to be the problem , get the multimeter out and check out the wiring, the manual will guide you

 

Thank you very much, i will reply with my findings. Its a very odd issue and sucks cause sometimes i like to go to miami and ride and having this issue sucks cause you cant ride around like this

 

About 80% of the faults are wiring and connectors , but I'm sure you can get to the bottom of it

 

Well, the bike had the issue again, returning from a nice ride, once i got home pulling into my neighborhood it did it again. Priming it, the fuel pump sounds like diarrhea, rough and mean.

But when the bike is running good, the fuel pump primes and sounds very nice and smooth

 

Have you had any fault codes
