Re: Idle Air Control
Glider, if it had a intake leak wouldn't the idle high not low, my 04 had a intake leak and was idling at 3000 RPM or are the new ones( 06 up ) with the 02 sensers adjust to the air/fuel mix. Would the 02 senser adjust for a lean condition?

Re: Idle Air Control
hello all well i got carb cleaner and real carefully sprayed around the intake and the bike did raise in idle just enough that i can do it on command. I watched out for the K&N filter not to get any spray in it. So i called the ESP and it should be covered so back to the dealer it went now just waiting for the call back. thanks rich.

Re: Idle Air Control
You wouldn't hear any hissing sound if the tank was full. Generally when the tank gets below half, you would hear it then.
