it rides fine, idle pulls it with no problems on 1 & 2 wheels, but sometimes well a lot ,if I get in to the throttle it bogs out like its running outta gas, so I filled the tank to the top thinking that the gas might be under the fuel pump and still had the issue... any advice would be cool figured someone may have dealt with this

oh yea its an 03 F4ezzy

 

might be the fuel pressure regulator going out.

if it works fine in lower RPMs but bogs out when you punch it in higher rpms that might be the case...not getting enough fuel.

 

na its like low end stuff like when you gas it a bit to stay up cause you hit the brake to hard and nothins there

 

thats the F4i for you. no ****in twitchy ness at all, u gotta slap new plugs in her and some +10 gearing.

thats just how the f4i is. if ur really smooth with throttle input it wont bog as quick.

 

wheeliest hit it.you have to gear the **** out of the f4i.it wont be as bad

 

its +12, gonna give it some new plugs and start the elimination process
thanx

any more suggestions would be awsome

 

ive got the same problem... bogs when you need it the most... i think gearing it up would solve the problem... my plugs are relatively new.

 

but if it was gearing wouldnt it do it all the time?

 

well i went down 1 tooth in the front... made a differance.

 

f4i is not twitchy, thats why 600rr has 8 fuel injectors.
