Has anybody experienced stalls at low speed..The bike did not die but it hesitated halfway through A turn had this happen twice..for all that have a new bike with his new engine be aware of this because it can happen and it's happened to me..make sure you stay on the throttle!!

Have occasionally noticed the same thing.

Well it sure wakes you up real quick.. in my opinion I think it could be running to lean at low speeds or rpm.. with good tune tts richen up a little should help at lower rpm.. I'm sure there running lean as my twin cam was.. better to be a little rich then to lean!!

Stumble and/or stall is not acceptable and can constitute a safety defect. I'd suggest people experiencing this not just blow it off but rather insist H-D fix it. This sort of stuff gets recalled in the automotive world, but Harley in the past has been immune for some reason. Now that the EPA has finally started paying attention to Harley, perhaps the NHTSA will do so as well. Don't forget guys, if you use a tuning device to tweak this issue yourself on a 2017, you will risk losing your powertrain warranty under the consent agreement between EPA and Harley. Make them fix it.

Wow - I agree with Jerry. That is dangerous and HD should fix it.

So...they still do this... my 13 had the same issue your discribing and it only got better after I had it tuned, so the more things change the more they stay the same...

Put a PV-2 tune to it and that stall issue goes away..

RonandJanet · « **Reply #7 on:** March 01, 2017, 02:30:00 PM »

I agree there are fixes but I think HD should fix it. The buyer should not have to invest more money to make the bike ride properly and safely.

My 2011.5 did this the first couple of weeks I rode it. I don't remember, but it had to do with the electronics learning where 'zero' was on the throttle input.

I do remember my mechanic telling me to completely remove my hand from the grip, and shut the bike down using the main ignition switch vs. the button toggle on the grip. He said that after a little time, the computer has built a set of memories where the throttle input is most likely at 'zero', and the hesitation should go away on it's own. Still, quite the eye opener when it happens.

Either way, I didn't have the issue for some time after doing that, and of course once I got the TTS Tune installed... it went away completely.

I still believe, like others have said... this is something HD should be taking care of, and not something we on the road should have to discover on our own.

All of my stalls were while entering into a parking lot... slowing down to look for a good space, only to nearly drop the bike while at less than a walking pace... with sudden loss of power.

Did this start for you right off the bat? I put about 2k miles on mine before putting her away for the winter, but I didn't have any issues. Just wondering if you worked into the stalling, or if it came right off the floor doing it?

FLTRI · « **Reply #10 on:** March 02, 2017, 02:00:21 PM »

Typically this condition is due to an off-idle lean area.
Unfortunately, due to emission regs, even bone stock bikes can experience these niggling hiccups.
Change the way air flows thru the engine (i.e.: aftermarket pipe, a/c, cams, heads, etc) and the condition gets worse along with other issues.
IME, a trip to a competent tuner and a few $ will eliminate this condition And increase performance in all other areas as well.
No downside to recalibrating for mods and emissions related run quality issues. Just upsides with smiles for miles.

I remember reading about this right off. A new owner experienced it thought it was from the lower Idle the new ones have. Good to hear it can be tuned out.

This sort of thing always could be tuned out, and Harley customers have been doing so for decades going back to the early days of basic emission controls on carbureted bikes. The issue is the customer should never have to "tune out" a safety defect in the first place, and stumble/stall is a safety defect. If people continue to spend money tampering with the tune on the current model bikes, they risk voiding the powertrain warranty. It was bad enough when everyone had to pay to make the changes required, there is no way I'd let H-D not only make me pay to fix their defect but also lose my warranty in the process. Why is everyone so afraid to insist H-D fix this?

My 15 did this, it stalled twice while rolling and one at a stop sign. Every time I took it back to dealer they told me you need to put more miles on it granted it was in first month of ownership. Once I installed Fullsac, TTS and Steve's map I have never had that problem again.

I'm calling HD customer service today.

any updates

I spoke to my dealer's service manager about a month ago about this problem. He and the lead tech were well aware of it, had experienced it themselves and noted a a couple customers who were picking up brand new bikes had almost dropped them leaving the parking lot because of this issue. Lead tech said it was due to sluggish throttle response from off idle and he had successfully tuned it out of other bikes. But I'm not paying any more Harley tax to get this sort of runability issue corrected. No way, no how. Been there, done that and not doing it again.

After speaking with moco tech support they wanted me to bring bike in to verify the ECM calibration - fancy way of saying to determine that I had not diddled with the map which I have not. It is bone stock. Service manager read ECM and advised that there was a newer calibration - 41000485B which he loaded. My bike had the 'A' calibration. Unfortunately it made no difference as I still experienced the hesitation a couple more times. I advised him of this and he is in consult with the moco again. Be nice to get this chit sorted.

I believe all the updated calibration did was to raise the idle 100 rpm and delay the eitms coming on to soon.

My wife's bike is having this exact same issue.

We purchased two 2017 SESG's on April 1st and I rode her's for the first time yesterday. Mine is not suffering from this issue, but on her's the throttle sticks a little at the very first 5 or 6 mm's and doesn't return completely sometimes.

I believe what you'all are describing is the same issue as in, the throttle is probably not completely closed sometimes when it is shut down. Her's idles about 100 or 150 rpm lower than mine too. I did stall it once and fortunately it was upright at the time. Two other times I almost stalled it going around a corner at an intersection and one of those times came very close to dropping it. You have to be ready to apply a good amount of throttle when this happens.

Never had a problem like this for the last five years riding our 2011 Limited's so this one definitely needs to go in and have the throttle checked.

I had this same thing happen to me on my 2016 CVO SG. I took it back to the dealer and they told me they had to reprogram it. But it happened a few times after that so I believe It definitely has something to do with the stock map. I purchased a PV2 and changed the map with an auto tune and so far so good I haven't had it happen since.

My bike now has 3500 miles on her and the stalling has no happened for over 2000 miles.

nothing new on this

pvanwagner · « **Reply #25 on:** May 22, 2017, 01:31:12 PM »

We took my wife's bike in for this and the tech written resolution was:

"Unable to replicate issue. Disassembled throttle grip assembly, cleaned and lubed friction points. Problem resolved."

I was a little pissed off when I picked it up because I could replicate it every time I rode it. After riding it I discovered that they had fixed the problem. The problem in my opinion was the throttle sticking slightly open and the computer picking that up on shutdown / startup and setting the idle to that position of the grip throttle sensor. That made it idle low when not stuck and casued sticking throttle problem at that barely open point.

Regardless, the clean and lube (dry lube) fixed the issue and her bike is running great. Just FYI for anyone else having the same problem.
