Weird idle and stalls after idle[Solved]

Ok so update seems to jerk/stutter under 25 mph after that its normal.[Sounds like a 3 cylinder]
Update: Fixed the issue, I changed out the coils and reset adaption and issue is no longer like it was :grin2:

Forget to tell a few things about the bike:
2014
20k Miles
Spark plugs changed
[Recent]
Replaced all ignition coils
Airbox is working

Did you service it yourself, a mechanic or the dealer?

How long ago (how many miles) did the problem occur from the service date/mileage?

Did you do a visual check to see if everything looks good inside your tank? Water in your fuel system perhaps?

Battery in good shape?

I think we need a bit more info and you need to take some necessary steps (examples provided above) and check off all the necessary maintenance items, regardless of how small, before and after this issue occurred in order to receive some more specific reponces.

I have the video of it stalling if that will be any help. a mechanic did the spark plugs, I did the clutch cable. And I just got it back today and the problem is there, they think its to do with the servo actuator for the airbox , And gas tank looks fine. Battery is also good.

You could also try a TPS reset as I had similar behaviour when I changed out the battery.

Here is what to do after replacing the battery,

1) Turn the ignition key on
2) Turn the kill switch to the on position
3) DO NOT START THE ENGINE
4) Roll the throttle full open, hold open for 2 or 3 seconds.
5) Roll the throttle off.
6) Repeat steps (4) and (5) three times
5) Turn the key off.

You're now re-set.

Well son why the heck didn't you just say so at the begining lol....I'll leave this to a more competent forum member as I have no experience with that part, but is there a way to rotate the receiving end on the air box so it lines up to the mounted servo position?? I know, elementary question, but....
 
#11 ·
I appreciate the help and I seen in another thread people said its ok to put them in manually, and plus I have done it before and I haven't had a problem. Just wondering why I am getting such weird idles now. And I will try the TPS thing too.

Throttle cable is unlikely, unless you feel a difference in cable play or feel. In my experience, ignition coils usually either work, or they don't, unless there is an issue with the way they are seated, or lack there of; it just came back from the shop to have the spark plugs changed, so that tells me from the little bit we know is the most likely culprit. If they are semi-reputable, they would own a gs911 or the like to at least read the fault codes associated with this issue.
 
#15 ·
I don't even think they own a GS911. I will upload the video in a bit of it cutting out, but yesterday when I was trying to hold a steady rpm it kept jumping by itself and I don't know if the airbox would cause that + it only happens when its warmed up

The seal is snug feels like theirs an O-ring there and the motor should be screwed down all the way flat. When the bike is off the cups should be in the up position floating above the throttle housing assembly . If I recall correctly they will cycle down up when you turn the ignition on.

Nah I believe its offset on purpose . The manual actually tell you not to remove the motor all the way ,I figured it was because of the offset way it sits once I had to set it back.
 
#24 ·
Im not 100% sure but would think as they are called Velocity Stacks and move up and down according to your throttle position it could impact the idle . Here is a vid I found that shows you how they should move. Looks like hes using a flat head screwdriver. You should be able to remove the air filter and look inside while turning the ignition to on and see them move from home position up to down and back.

The servomotor for the stacks doesn't line up. You can turn the ignition on with the servo plugged in and it will rotate allowing you to line it up and fit it correctly. If you have verified the plugs and coils are all fitted correctly then it could be that for sure. I see in one of your pics that the secondary air pipe has a bolt loose. Did you loosen that to get the coils out?
 
#27 ·
If you had a GS911 it would probably tell you what the problem is. The engine light came on when it stalled on you at the lights. Most likely a air box issue. If you think it's not running on all cylinders get a temp gun and check head temps. If plugs and coils are in correct then it's probably not that. Idle issue sounds air box related. All sensors plugged in, all hoses connected.
 
#33 ·
As it has been stated, you will need to obtain a GS911 to see what the bike is telling you. Otherwise, you'd probably spend more money replacing parts. Not to mention time and the frustration level you've been conveying. The unit will almost always pay for itself upon first use. Once you read the fault codes, post them here if you require help with further diagnosis.

Alright so I caved in and purchased a gs911:
