i think honda is going to be the best bet

 

ok thanks i just ordered a new one

 

I have had a similar problem with poor fuel delivery before.... the solution turned out to be a bad battery. The fuel delivery was okay if the rear brake was applied and I know this sounds crazy... I traced the wiring diagram and the fuel cutout relay the affected part ...too low voltage. I replaced the battery and all the issues went away.

 

You can always bypass the fuel pump also. The only reason the cbr has a fuel pump is the lower portion of the tank is below the carbs. If the fuel level in the tank is higher than the carbs you can pull the fuel line off the pump and place it on the filter... this is not a permanent solution but it can get you home. The bike runs normally on gravity feed.

 

thanks for the info i go see if it worksi am still gonna replace the fuel pump and get a new battery

 

i have received my fuel pump and i straight wired it it works!!! yes well i havent had time to try to get it to start how much fuel should it pump out in 5 seconds i have a seringe to mesure with ok thanks for all the help i also got a new battery and that seemed to help a little i think thanks again.

 

Hey guys, I just got my hands on a 600F about a weekago. I've been riding it around and it's been fun. But, the other day it died. I've been running tests trying to figure it out. On a fuel injected system this is a legit test, but I've never worked with carb'd motors before. If I disconnect the fuel line going out of the pump to the carb, try to start the bike, fuel should be pouring out correct?

 

it may not pour out but it will pump out
hope the best of luck to you i got mine all taken care of and am in the process of painting now

 

as soon as you turn the key on it should be pumping out, dont even need to roll over

 

when i turned the key it started to pump once but to get it to go i had to turn the bike over
