High idle. 2400 rpm cold. 1800 rpm hot.

Hi,

Does someone have problem with high idle. Sometimes, just from somewhere engine idle are 2400 rpm after engine start, when it is on working temperature idle goes down til 1800 rpm.
This can last for a few days and just gone. Normal engine idle Cold 2000 rpm, hot 1200.
Last time idle just go down from 1800 rpm till 1200 ( working engine temperature) when i stand up on foot peg when motorcycle was sit on side and just sit on motorcycle.

Any ideas whats can be wrong?Temperature sensor? Idle air control valve?
Connect and disconnect battery does not help.

Sounds like a sticky throttle cable, what happens when you snap open the throttle & close quickly, do the revs drop, do the revs change when moving the handle bars from lock to lock, how much play do you have in the throttle before the slack is taken up?

Did you get this issue resolved?

I am having the same issue on a 16 CRF1000

High idle just started overnight. The cables are good. Going my the Honda manual, I am guessing it is the IACV

Hi ghostrider, what kind of Bosch tool do you use?
Is it connected to a pc? Or a a professional multimillion dolar dedicated tool?
Some year ago I had a bosch car service workshop and had a diagnostic bosch tool, for cars, wich connected through OBDII connector. Easy for german brands but not so for british, french or asiatic brands.
Thanks.
