Alright guys, I have a 2007 CBR 600RR. I have had issues with the idle for the past month. Here's the deal: RPMs would go up and down when riding around with clutch disengaged (bouncing off the 1, 000 RPM mark=almost like it is stalling/in limp mode). Then after a few days of riding, the bike idles higher at normal engine temp and will idle even higher with a rev of the throttle (~2,000 rpm). There is decreased engine breaking when using gears to slow down and bike jumps a little when shifting gears (like throttle is being held down=obviously the high idle issue).

After all this, I replaced the IACV (air intake control valve) to no avail. Decided to say screw it and took it to the Honda dealership. They hooked her up and said the air intake temp sensor (IAT) was throwing a code. They reset the ECU and said it was good to go. The tech said further that if it does the same thing again, I should replace the IAT sensor since it has gone bad.

My question is this, my bike never threw a FI light blinking code or anything of that matter. So, how can resetting the ECU temporarily fix a faulty IAT sensor (if that's the case)? The part is $15.00, so I am not too concerned about it. And it is easy to replace. I just wanted to see if anyone had this happen, has an answer for me, and to let everyone know that this issue is NOT always related to the IACV.

Thanks in advanced guys!
