So, Mr. MTBIG, I would like to first say that you should act like an adult instead of a kid that got laid for the first time and tries to impress others.
For the thread, DynoJet has also reported issues with idling, searching for idle, etc. Harley does have a problem with it and the dealer where I live is also aware of it. They even have an update program for it.
Lastly, I don't really care if you believe what I stated about adjusting my own program. It worked on my scoot and I simply passed on what I did to make things correct.
For anyone else on the string, I can give you exact procedures if you want to know but you will have to contact me directly as I really don't have time to play with sandbox trash like Mr. T.
I have a 2017 Road Glide Ultra for 5 weeks now. Had the 1,000 servicing and now I have 2,000 miles on it. Last Sunday my bike stalled twice and today it stalled once on my way back from a dealership. They did the bike isn't generating any codes.
So here is when it's stalling. I'll be downshifting to come to a stop. I'll get down to first gear, and as I get ready to stop, I'll pull the clutch in, to apply the brakes, and the RPM's drops so low that the engine just dies. Sometimes it drops to 500 RPM before I goose it with gas to keep the RPM's up. So it's stalling when I come to a stop. I suspect the RPMs do so low that it just shuts itself off. At times it takes a while to restart the bike. This is a dangerous situation because who knows where I'll be when I can't restart my bike.
My bike never stalled during acceleration and it's always been rolling to a stop when the clutch has been depressed.
I noticed that with the new road glide so I tried putting sea form in her at 6 ounces for 6 gallons and it made a big difference, must be crap gas we are getting that you pay top dollar for

Nothing like regretting attempting to help....
Use the friction zone.. Keeps the Rs up.. It's not an automatic clutch. The clutch will grab and motor stall if you don't.
Add. Part of it is the slip assist clutch.. Needs getting used to..

Dundee. Try to understand that in your very first post some fairly outlandish statements were made, such as:
"The M8s have both a problem with stalling on take off as well as stopping. Engine shutting off while in a very slow speed turn such as pulling out of a stop and making a turn."
Really? I admit, with the new slipper clutch take offs are different and take some getting used to, but stalling and engine shutting off?
"And Harley is dodging recalls and liability with this problem."
Really? Calling BS here.
"the bike shuts off while you are under 10 mph"
??? WTF
"it is EVERY M8.
No! Not every M8. Niether myself nor anyone I know personally with an M8 have had any of the issues you described.
Your saying dynojet has reported these issues. Where? Is there a link?
You adjusted the VE tables, idle etc... with what tuner?
Lastly, I didnt attack you on a personal level. I simply called BS on outlandish statements in your post, especially since it was your first; no introduction, no bike listed, etc. You, on the other hand, are are trying to make things personal. I'm not biting. Simply dont belive anything you've said.
I have had a few customers with the complaint. It's brought up during the pretune discussion. I have never done anything to address it. Just tuned the bikes and problem went away.
A couple of things I don't like about how the stock cals are set up. Leaner than I like to see in the 20kpa deceleration area of the lambda target table. I run this area rich enough to get it out of closed loop values. The other is I raise idle. Some are set up as low as 940. I like closer to 1000.
I'd bet that the factory tune does have something to do with this.

The stockers were set to 840. Stage 1 and above were moved to 940.. The lower idle does kill the throttle response and its 100 rpm closer to a engine stall.

A Harley Tech came to look at the bike several months ago and he determined it was a faulty clutch switch. They replaced that and the issue is completely gone. I have put on 3k miles since the fix and all is well.
I could see how a bad clutch switch could do it. I've never stalled mine in the 2600 miles I've put on it, but I almost stalled the demo bike on the first clutch pull on my first M8 ride.
