High idle on its own
« on: August 13, 2016, 07:07:44 PM »
I have had this just happen for the second time.  Was out for a 30 min drive, normal, no high speed or  puttering (cause it still can't be driven between 0-15 kmh).  Stopped Bike while in High.  Got back on, pulled hand brake, started and it was automatically idling at 3600rpm, as a result the machine took off on its own.  Couldn't get it to idle down.  Held on both brakes to get her stopped...  Turned it off.  Put it in Neutral, started and it went back to its normal idle at 1700rpm.  Any ideas???

In my opinion this is dangerous and can result in an accident or someone getting injured.  Definately a safety issue!

Are you touching the throttle after the key is on and before running? Even with the injector at max pulse width, I don't think it can get 3600 rpm with the throttle plate closed so maybe you better get it in to the dealer..your throttle body may have a problem.

I would think that if the throttle plate was closed, even if it was dumping fuel in, it wouldn't run at that rpm. Did it let you start it while in gear? I don't think it should.

Maybe he has a bound or twisted throttle cable and it's holding the throttle somewhat open. Does the throttle ever feel different..like easier to move then other times when its harder and maybe not so smooth?

Thanks folks.

Being fuel injected I do not touch the throttle when I start the bike.  When I turned it off the RPM was at approx 3650 without touching the throttle.  It started no problem while in gear but idled up to and stayed around 3600.  That's when I shit it back off and put it into neutral then it ran normal once I restarted it.  The throttle doesn't feel any different then normal.  Normal being:  if I rev it up to approx 4200 rpm, I can let off on the throttle ALOT... Maybe 3-5mm before the rpm drops, been like that since day one and it just drops abruptly from roughly 4000rpm to approx 2800rpm.  That's the issue I have questioned on here in another post. Throttle feels the same as it did on day 1.

I Appreciate all the feedback.

To check and see if the cable is getting pulled, start it up and turn the handlebars from one side to the other. Idle should not move at all. From what your saying, sounds like the butterfly is sticking or the return spring is not pulling it shut to idle or bad cable. I did check on the starting in any gear and yes it will. I don't think this was a great choice on there part. I can see something bad happening starting in gear.

I checked by turned the handle bars, even tried jiggling the cable.  It had no effect on the RPM when I did it.

OK. My next move would be to get a good look at the throttle body. Keep moving the throttle and watch how the butterfly moves. Watch for any sign of it binding or hanging up. Reach down and check the spring and make sure it's working.

the correct idle speed on that machine should be 1400 +/- 100 RPM. The 1700 you are referring to is already high. The machine doesn't really have a idle screw, its more what I would describe as a throttle plate stop screw. The IAC controls the idle circuit. I am guessing that stop screw needs an adjustment.

Z8rider, thanks I will pass this onto my dealer when I drop it off tomorrow.  I wonder if the Idle, which is normally 1700rpm, has anything to do with why I cannot maintain a constant speed between 0 -15km/h.

It may very well. 1700 is absolutely to high for idle on...anything.

On Saturday, I cruised mine for around a half mile doing 5 MPH, Also, I notice I'm running at less RPM's to do this as well since before. Machine is breaking in nicely.

Good afternoon. I found this post just reading through stuff the other day but hadn't paid attention to where mine was idling. I caught a break in the rain took it through the woods for about a mile and a half enough to get it up to full temperature. And mine is idling at 1650-1700 too

Looks like they still have a bug to work out of these.
