Stalling...Power Commander?

[Ron_Luning]

I've been embarrassed and more importantly put in a pretty dangerous situation a few times already with this stalling right off idle at traffic lights. I have always used 91 octane; ethanol free isn't really an option in southern California. I haven't heard a ping as others have described. This is literally the only bike I've owned to do this, and that includes several with a cable actuated clutch, several with a hydraulic clutch both with and without fuel injection.

I don't want to spend any more money to fix things that shouldn't need to be fixed, but for those who have tried the Power Commander V with the stock exhaust, are you having this issue?

Anyone else having this stalling without evidence of low octane fuel? I seriously almost got my foot run over last week, and I'd rather not have to slip the clutch like this was a 600 supersport.

I'm all stock, but did you have this problem before the mods?

 

[Ron_Luning]

Sorry for any confusing writing. My bike is stock as well. I'm just wondering if adding a Power Commander will resolve this issue.

 

[Ron_Luning]

Also, I was thinking that what others have described as a ping, may actually be the single noise of the starter motor clutch engaging as the engine rpm falls below the disengagement point. If a ping is occurring from low octane fuel, it should be happening constantly.

Hi Ron, we should get together. I had a similar issue and the bike is completely different with the slip-on and PCV. I am running my own modified map from Blue Eyes European map. It is pretty good. I am going to schedule a dyno with Cycle Visions in about a week. You can fix the issue.

Devin,
I'm going to try running sport mode with TC turned off for a bit to see if that has anything to do with it. I'm trying to avoid the slip on route because I like the quiet exhaust, and my neighbors probably do to. I'll let you know how it turns out.

Hey Ron,

I mentioned this problem when I took the bike in for its first service. The service manager was able to contact Yamaha and get a fix that involved the CO settings. The mechanic had to find a jumper (whereabouts unknown to me, TOP SECRET apparently) in order to get my California bike to talk to him. After the service the stumble/stall problem was completely fixed and the bike seems to pull better off the line and fuel better at low RPMs. For reference my bike had the motorrad pipe with baffle installed at the time but no other mods, and I run 91 octane.

Judging by the response from Yamaha, this is a known issue. I am still planning on installing a PCV, but I bet your dealer can fix that problem without it.

Looks like a 'jumper' mod ala the FJR's is in store for the ST. Just have to figure out what they jumpered!

Ron, that does help with the problem, so does Rods up the idle a bit thing. I don't think this happens much to folks that do not blip the throttle on take off, so they may not have it happen to them as it does or did with me.
I am convinced now it does make a difference as to the quality of fuel you get. I am adding Lucas octane booster now in mine and it went away.

I also cannot stand how the motor falls on it's face taking off riding 2 up on TC1 and for that matter TC2. I like it off on the dry, but may be that's just me :question: I like a consistent motor, traction and bike, otherwise it messes with me and my riding style.

I would still like this bike even without all it's electronics and pay the same for it, but don't tell Yamaha that. Some of the options are nice in the right conditions, but I don't need them to enjoy or ride this bike. ::001::

Great! Sounds like they have a fix. I would even be a more happy camper if a true fix was known. Did they tell you the password my Yamaha tech needs to tell them for the fix :question:

I hate patching a problem like fuel octane booster. ::007::

No stalling present in my 49 state bike. Could be a CA issue.

I'll try to get some more info from the service manager. They seemed pretty tight lipped about it, but I could ply them with beer (may I reiterate the OEM panniers can hold a lot of this)

No stalls on my California bike, in "T", and full traction control. Is there a reason you can't take it back to your dealer, or a dealer, to have the fuel mixture richened up a bit? I know it's super secret, but some tech somewhere in your region can ask the right person for the procedure. It's free, that's why they call it warranty.

I'm up in WA and I think I've got a CA bike (not unusual for up here - but would need to verify with VIN).

As mentioned in another thread I did have a few pings - but the bike seems to have corrected for that.

Here's a thought - these things are run by computers. Reboot yours - disconnect the battery, let it recalibrate and then see how she behaves. I did this because I put a power/charging cord on mine & things are going well. Worst case - take it back to the dealer & demand satisfaction!

 

[Ron_Luning]

Maybert: I sent you PM, but basically my dealer didn't get any info from their Yamaha contact and would like to be able to talk to your dealer to get more info. What dealer or individual can they talk to where you had your bike serviced?

 

[SpeedStar]

Ron and Maybert, please post what you find out here as I will want to discuss this with my dealer too.

 

[Maybert]

Hi Ron - PM sent

Hi Devin - I spoke with the nice folks at my dealership and the owner mentioned that according to Yamaha is a not a "known issue", but rather Yamaha was able to give her a "recommendation" on how to fix it. I suspect that my bike is now classified by Yamaha "For Closed Course Racing ONLY"

I think when it comes to anything FI or emission related everyone is afraid to give an official answer for fear of repercussions from the EPA/CARB.

 

[stevepsd]

No stalling or pinging issues with my 49 state bike.

 

[spasm]

not being funny but why would u put a power commander on with the stock exhaust???? throw another £500 at her and get a full system otherwise ur wasting ur time

To check for a CA bike, see the CA section on http://www.stadiumyamaha.com/pages/OemParts?aribrand=YAM#/Yamaha/XTZ12BL_-_2012_-_SUPER_TENERE/FUEL/XTZ12BL_(2012_MOTORCYCLE)/FUEL_(XTZ12BL_-_2012)

On my WA bike I followed the hoses up and they go directly into the gas tank, no magic CA box. And zero problem with my bike and never stalled it. At 500 miles, the engine just keeps getting better.
