i would like to know if there hsould be any certain specifications to taking care of a cbr f3, ive already the complete carb clean up last about 6 months ago, got new plugs, oil change, my mechanic even hooked up an R1 fule pump to it.....etc, now just recently i went for a little ride and jsut as i am getting home i can feel the exhaust shooting off spurs's of air, my idle was having trouble keeping itself stable and then i got a nice wiff of gas thru my helmet, i tried starting it back up and it couldnt hold its idle, it just kept shuting off so now it wont start, so im thinking i need a new fuel pump, could i be wrong???

 

why an R1 fuel pump???

 

an intermittent stumbling idle wont be from your fuel pump, unless it is surging, but even then its a long shot. I say check your plugs, even thought they are new, check your air filter, check simple stuff first, them move on in. The biggest thing I have learned from when my 96 acts up, its probably something I did, and it doesn't like it or its not completly dialed in. good luck and let us know how it turns out~

 

to be honest it was out of an emergency that we had, so it was either that or tow it



i was actually thinking the same thing, but that fuel pump is on my mind for some weird reason, i think bc it was used when we put it on used but i will defenetly check everything out tomorrow morning, thanx for the help

 

turns out the plugs werent new, i was actually thinking about a different F3, my bike on the other hand has to get new plugs, because only 3 were working, the fuel pick **** needs replacement, new fuel filter(or air filter i forgot which one) and labor

 

I have a 97 F3 and when my fuel pump needed changing it would be running fine then act like it was running out of gas. I could usually sit there for a few minutes and take off. I bypassed the pump 1 time to try and diagnose the problem, sure enough it was the fuel pump.
