convenient posting. mine would idled down to 500 and then stalled while on going-to-the-sun highway. i reached down and turned it up, problem solved, but wasn't sure about the proper setting now that i'm back home. i had it at ~900. thanks!Your idle need to be set to 1300 rpm's when warmed up...
Which is the sub-throttle sensor?You can bring it down by rotating your sub-throttle sensor counterclockwise a bit... I had to after rotating my main throttle sensor counterclockwise by about 0.5mm to add low end fuel and cure lean stumble. My sub-throttle plates were already removed, by the way.
Set you normal warmed up idle to 1300 rpm, as it should.
It's the upper one... What's your elevation above sea level? Is your idle always good and stable once warmed up? Is there much of a lean stumble, mostly near 2,800 rpm?My '15 650 just started doing the high idle thing in the past week when it has gotten colder. Only the first start when it is cold soaked to 45 or colder. After about 30 seconds of normal idle it then zooms up to 3000 to 4000 rpm. If I hit the kill switch and restart it, the rpms are normal.
Twice the idle has been normal until kicking it into 1st gear, then the rpms rise.
Once warmed up the engine runs, idles, and starts completely normally.

I'm still not sure what the sub throttle sensor is. A photo might help if you have one.It's the upper one... What's your elevation above sea level? Is your idle always good and stable once warmed up? Is there much of a lean stumble, mostly near 2,800 rpm?
I adjusted it a bit and the stumble is almost gone. The exhaust note is a bit throatier sounding. Today at least it didn't rev way high at startup, though the temperature was around 50F.http://www.kawasakiversys.com/forums/9-technical-discussion/16031-versys-kle650-2010-2011-service-manual.html
They are on the left side. They may be partly hidden if yours has the evaporative system charcoal canister over it... Here's aka Yamadog's photo, with a T25 Torx tool on the Main Throttle Sensor screw. Start by rotating your Main Throttle Sensor (lower) counterclockwise by a very small amount (about 0.5mm). Before loosening Torx screw, look at how the sensor's green reference mark ligns up on the front, with your head against your front left turn signal... Then we'll consider rotating your subthrottle sensor (just above) counterclockwise as well if your cold fast idle is still too high
Cool... You can experiment a bit by adding more or less counterclockwise rotation of you main throttle sensor.I adjusted it a bit and the stumble is almost gone. The exhaust note is a bit throatier sounding. Today at least it didn't rev way high at startup, though the temperature was around 50F.
