Idling issues
Hello everybody,it's been a while
I'm not sure if this question has been asked here before but here goes
My engine Idling speed seems a little high hovering at around 1,500 rpm but when I carefully blip the throttle a few times it seems to settle down to about 1,000rpm.I can understand when the engine is cold and the auto choke is on but this happens even when the engine is nice and warm.It's a 2013 SG btw.I had cleaned the air filter but it still persist..any clue guys?

Not sure if this applies to HDI models, as I have no experience with them, but have you performed the throttle zero position reset procedure yet? With killswitch in run position, throttle untouched, cycle ignition on for 10 seconds, then off for 10 seconds. Repeat 4 times.

It used to be the case where the throttle by wire would not read the "0" throttle position correctly if shut down while partially open, or started while partially open, etc. It would lead to high idle on warm starts, but it was supposed to be fixed.
I haven't heard much about it for a while. It can't hurt though and takes very little time. If it doesn't fix the issue, I would see if it is possible to take a look at the readings in the SEPST you have and what it is reading for idle throttle position.

Ok,I'm gonna try the simple method you recommended first and if that doesn't do it,I'll try and check it with the tuner when I take the bike in for service next..I'll keep you posted.Thanks buddy.

My 09 is really sensitive to this and using the kill switch to shut down the bike will almost always result is a non-calibrated throttle sensor...and an idle closer to 1800 rpms.
as above cycle the ignition on and off 4 times pausing a few seconds each time,using the ignition switch, not the kill switch...with your RIGHT hand so that the throttle is untouched while you are doing this.
I have had to get in the habit of using only the ignition switch to shut down the bike.

no on mine ( and the earlier version like my 09 seem more affected by this), the idle will remain high.
my ( our) fault is that the "zero" position of the throttle position is lost if I use the kill switch.
your problem may lie elsewhere, but to reset the throttle takes only a minute to do
to delve deeper would be to look for trouble codes, check settings if a tuner has been added, and I would think on a stock bike we could check whether the temp sensor or other sensprs are working correctly- esp as you and I are in warm climates and a "choke" to start a cold motor is almost never required.
