I have a 2000 cbr 600 f4, first starts up runs fine. Ride it ride it around the block, starts to cut out like it's running out of fuel. Bypassed the fuel pump still does same thing. Any ideas

 

Evening mate.
When you get the symptoms you describe is it as your rpm increases ? Will the bike behave when you ride with small amounts throttle ?
Tell us more about the bikes recent history as it will help.
Cheers.

 

Yes it will sit an idle but when I give it throttle it don't respond, it just started doing it a couple weeks ago. I put new plugs in it an it fixed it for about 2 weeks. I was on the freeway an just started losing power, pulled off the road and throttled it up a couple times an it was fine. Then on way back home. It stared again, an stopped next day went across town started dieing on me and didn't want to start. I pushed it back home, ran fuel line straight to carb started no problem. Road around block an just got home it started doing the same thing acting like it was running out of fuel, or not running on all cylinders.

 

Have you looked at the jets to see if they're clogged? If you take them apart, run a thing wire through them, just in case.

What about the fuel filter? (If this model has one)

 

Well I changed the plugs again, an pulled the carbs and cleaned them. put it all back together runs fine. So not sure which one it was,but problem fixed, thanks for them info, I save myself a bunch of money an did the work my self.

 

Well done mate. Always nice to fix yourself.
