"Plenty" is personal opinion. If Honda designed my F3 with "PLENTY" of power, why did I add a full exhaust and Stage 2 jetkit?

 

well i have a 93 cbr f2 with stage 2 jet kit and and upgraded chain and sprocket for speed i diy coil over spark plugs from a 2001 f4i and she runs great until i hit higher speeds my gravity feed fuel pump/petcock cant keep up with my fuel consumption and in higher rpms she starves and i have to let her get fuel back up by while riding by holding my clutch till she starts running good again. while riding with my friends this can be really frustrating cause you have to slow down every 10 minutes but i tried to add a fuel pump with the petcock from an f3 while i idle she floods and fuel starts running out of the overflow from my carburetors but in highway she is fine. just need to make a way to keep it running in high rpms but turn of when in idle idk how to do this lol

 

Sounds like the floats aren't putting enough pressure on the needls to stop the flow with the pump in place.

EFI bike do require higher fuel pressure to work, so they do need a pump.

 

Cheers I knew it didn't need a fuel pump, thx for your input boys.
