I can start my CBR 600 F2 and ride it for maybe 5 minutes and then if I try and get out of first gear it dies. Also it tends to idle weak and just dies out. i believe it may be the carbs but not sure so want some ideas before i go and take them apart.

 

Have you taken the gastank of recently? Sounds like a pinched fuel line. If it isn't that, try so seafoam in the tank top get rid of gunk.

 

any vacuum hoses not plugged???

 

I haven't taken off the gas tank so i doubt that, but the gas that is in there is pretty old, that might have to do with it. and where can you buy seafoam?

and sickcbr ill check on that and see.

 

You can buy seafoam at any auto parts store, 1/2 of a can will do you. But I recommend any way you can emptying the tank and putting a tank full of 93 octane plus seafoam. Lower flashburn on the 93 then switching to lower fuel after that. You might want to think about new sparkplugs and cleaning the carbs too. Make sure the vacuum hose on left side of the motor is plugged in too on the side of the valve cover to control fuel on the petcock and the arrow is down on the petcock.

 

ok thank you! and if i take my carbs out and hand clean them can i just put them back in or do i need to go out and buy a stage one kit and then i can put them back in?

 

A stage 1 kit wont be nessesary if you have stock exhaust and paper replacement air filter. Check out the carb cleaning sticky at the top of the page.

 

thank you for your help guys! i guess tomorrow ill empty the gas tank take out the carbs clean them and then re-install everything and hope that solves the problem!

 

Maybe spraying aerosol carb cleaner into the carbs while its running wouldnt hurt. Short burst into each carb. It tends to choke it out. No long drawed out sprays. You'll have to get a make shift fuel tank to do this. I use an old lawn mower fuel tank. If that dont work, clean that tank, carbs, make sure vacuum line is hooked up to the petcock. Also make sure the carb boots between the carbs and engine a tight and not rotted or cracked. Good Luck

 

That sounds like classic fuel starvation - as the others have stated, petcock/fuel/fuel lines.

Once it dies on you, crack the gas cap open, then try restarting and see if it acts better. That is usually indication of a plugged vent hose.

Very well could be a prob with the vacuum line to the petcock, or the diaphragm in the petcock. either way - the carbs are gravity filling when the bike is allowed to sit for a while, but under power something in the petcock system can't keep up with demand.
