Idle - too high

ninja_sleeper · August 29th, 2011, 08:47 PM

Is sounding funny. Idles at 3k rpms. I feel like this is more than it needs to be. It's sounding like she is over doing herself. In neutral it's at 3k rpm. When I first turn it on it's at 2k, then after I go she idles at 3k. Sooooo I am not sure whether I just noticed this or if it's a little off.

LOL is your choke on?

eds2fitty · August 29th, 2011, 08:53 PM

had the same problem when i first got the bike... there's a knob on the left side fairing that you could turn to adjust the idle...

yea..i just asked if her choke's on.

blink · August 29th, 2011, 08:55 PM

that knob tho it's technically a choke. just in a different area for permanent idling solutions

its not the choke on the handlebar... theres a knob on the left side of the bike on the body where u can adjust the idle, kkim had a thread about it but now the pics are gone...

Alex · August 29th, 2011, 09:01 PM

First - this needs to be in the tech section. Next - have you read your owners manual? The knob they are talking about isn't the choke lever on the handlebar. If the choke is off, then adjust the idle knob once the bike is warmed up (after a 20+ min ride or so), so the idle is steady at 1500. The idle knob is down by your left knee, peeking out of the bodywork.

It's the black knob directly to the left of the end of the electrical connector I added below:

Yeah they don't mean the choke they mean the idle knob. Alex is on target as always.

ninja_sleeper · August 29th, 2011, 09:11 PM

I haven't touched it why did it change???

Trailerboy531 · August 29th, 2011, 09:12 PM

You may have knocked it without knowing, it could have vibrated just from you tearing up Oregon. Stuff happens!

Alex · August 29th, 2011, 09:16 PM

For it to move a ton instantly, the most likely cause is the choke. Make sure that the choke lever on the handlebar is fully off, but while you are doing that pull it on and off to make sure that it's moving in the right direction. Pushing it away from you should shut the choke all the way off, pulling it towards you will raise the idle and make starts easier. Make sure that the choke is working either way, and it's not just sticking on for some reason.

But, if you've confirmed that the choke is functioning, and it's off, and the idle is still a little high, then the next step is the idle knob as listed above. It drifts over time as the bike breaks in and continues to wear.

setasai · August 29th, 2011, 11:32 PM

+1 on what alex said but just for the sake of thinking outside the box... if a mouse or something got stuck in your airbox and impeded flow of air it'd cause "choke" like symptoms.

It was on a DIY here, but all the pics are gone

True, they're not technically the same but they both cause similar results... basically an increase in idle rpms. I dont think blink intended on confusing anybody, it's more of a simplification.

squaregamer476 · August 30th, 2011, 12:03 AM

hmm, i don't remember seeing that knob. I have my battery charger plug-in around that area. maybe i missed it...

squaregamer476 · August 30th, 2011, 12:04 AM

found it. i didn't know it had any purpose. =P

Ehh, by the way he's phrasing it though (ie by saying technically), it makes it sound like he thinks it's a choke which it's not at all. The choke isn't just affecting your idle rpms which is why it's a bad idea to ride for an extended period of time with the choke on. It affects the fuel/air ratio so it can foul up your plugs pretty quickly since you're running rich (so remember to turn it off after the engine is warm).

The idle knob on the other hand just prevents the throttle from fully closing. It doesn't affect your fuel/air ratio, but wastes gas at idle if set high.

Yes yes. I'm just giving him the benefit of the doubt since writing can be misinterpreted and I think accusing him of intentionally misleading the OP is just a hair offensive. Thanks for explaining it more clearly. No argument/disagreement intended.

ninja_sleeper · August 30th, 2011, 09:19 AM

Turned it on this morning and it wasn't as high as yesterday. I did mess with the idle a bit when I got to work and brought it down to 1500. If was not the choke, that was the first thing I checked for.

Thanks alex for your knowledge. I am glad it was a simple fix.

Oh and my bike didn't come with an owners manual

If it did, I would read it.

Okay so you just rephrased what I said making it true...concept wise

the more your throttle is open the more air goes through your **** right?
so therefore when you open your side knob it varies RPM's because of the quantity of air and fuel ratio.

blink · August 30th, 2011, 10:11 AM

Just like in a car when you rev in neutral you allow the throttle bodies to open,
when you pop your hood and rev it with the throttle body control its the same concept

Not sure if you're understanding the difference between the choke and idle knob. Choke adds more fuel through the enrichener circuit and not air, so you will be running rich (more fuel/same air).

Idle knob just prevents your idle from closing, but your fuel/air ratio remains the same.
