07 cbr1000rr poor idle

Hi, my 07 fireblade idles really lumpy when warm, fine on initial startup but gets worse as it warms up, its perfect just off the throttle and flies, if i increase revs via throttle by a couple of hundred this also cures it, its a right pain as it stalls very easy in traffic due to this problem, any ideas???
cheers spillers.

What rpm is it idling at?
Have you tried raising the idle?

900 is way too low.
Of course you can adjust the idle :-)
There will be an idle adjusting knob somewhere around the throttle bodies, probably around the left side under the main frame.

Re: 07 cbr1000rr poor idle

I always thought the idle was controlled by the ecu...

Nope - there's a little adjuster. Looks like this:


If the bike isn't braking properly, you don't start by rebuilding the engine.

No, the idle is determined by the amount of air being allowed through the throttle bodies, and that is set mechanically by opening the throttle plates using a screw.

Re: 07 cbr1000rr poor idle

thanks but cant find anything like the pic sky91 posted, someone suggested thats only on the 600, as for adjusting the throttle bodies it looks quite complicated....

Then maybe the idle adjuster is missing, but I'd be surprised it idles at all if that were the case.

There are only two adjustments on the throttle bodies and neither is difficult.
Synchronising the starter valves, and synchronising the throttle plates using vacuum gauges.

Re: 07 cbr1000rr poor idle

You might also have a bad fuel pressure regulator. The symptoms you describe fit.

Re: 07 cbr1000rr poor idle

My 07 has the idle adjust where Sky91 said. It may have an overflow pipe in front of it or a water pipe. It is definitely there, it's awkward to get to

Do, or do not, there is no try !
