Don't forget about the EITMS Engine Temperature Management feature that shuts the rear cylinder off under certain circumstances. While flashing my 24 today, we turned off that feature in the ECM. I've never seen it happen even on super hot days last Summer, but then again my 24 never gets super hot like my Rushmore bikes did. If you don't know EITMS exists, it may shake you to the core when your rear cyclinder cuts out at a red light.

This guy explains it.

Hey everyone. Just found this issue after getting my ass kicked by a cylinder randomly dropping out on a bike with no codes showing.

View attachment 494717

This is the factory coil wiring. It’s
retained with a Christmas tree zip tie and then folded back on itself and zip tied again. Bike was randomly dropping a cylinder with no codes. Thought it was in my tune, kept checking, wasn’t finding anything. Happened to push on this plug while the bike was running (thinking I didn’t have it snapped on) and both cylinders started firing, let go and a cylinder dropped out. Found this when I pulled it apart…

Three of the 4 coil wires broken. So, I recommend if you have a 23.5-up center cooled touring bike, you cut the bottom zip tie that is folding the wires back over. Just passing this along to hopefully help others.
As soon as I saw you posted that I went right outside to look. Man if that isn’t the dumbest factory work.

Did you have to replace the cord? This just happened to my bike. Only one cylinder is activating.
I had to solder some length on to the 3 wires that were broken and then put new sockets on.
 
This didn't apply to me when I read it back in April, but my brain was saying...."isn't there a zip tie that @crazy4ink told everyone to cut by the coil"? I couldn't remember the title or if he actually started the thread so it took me a bit to find.

Glad I did because mine was bent beyond 90 degrees. lol Posting so this will get brought back up in the threads again for all the new bike owners.
 
I cut mine over the winter when @crazy4ink posted this notice. Last week my bike started cutting to one cylinder intermittently and throwing a code for the front coil (P2300 -- Ignition Coil Driver Low/Open - Front). My dealership tested and found the coil to be on its way out. They ordered a new one and my bike has been running great again since.

Thanks for bringing that thread up ! I cut it on my 24 and completely forgot about it - just went and cut it on my 25 :)
 
Had my '24 limp on one cylinder this past weekend, threw up the yellow check engine light. Shut her down, yet the light remained. Checked for codes, none listed. Decided to ride it to my local HD dealer, she ran like normal all the way there. Got the service manager scratching his head....then out of nowhere the light goes out. All is well, but still drove me nuts as to why it went limp.

Now, it was blistering hot, 96+ here in east TN that day, and it happened about 10 minutes after a quick stop at a gas station. Bad gas? EITMS? I had no idea till I saw this post. I'll check that coil zip tie as soon as I get home today. You guys rock, and typically know more than techs at HD. Keep up the great work.

Cut the zip tie and check to make sure the pins and the wires in the connector aren't damaged

Happened to me just over a week ago, but I got a code for the coil. It would be there, then would disappear, but remained as a historic code. It happened repeatedly.

The dealership diagnosed it and found the coil to be failing. They replaced it and now no issues in 1000+ km. When they replaced it, they didn't put that zip tie back on, either, thankfully.
 
Removed that zip tie, my pins and wires all appeared to be fine. Maybe that time was there to keep the wire from possibly coming into contact with the heads? And just an assumption.....the sheathing around the coil wires has enough insulation in case contact is made? What do y'all think?

Got to see this first hand the other day on a CVO. I cut the zip tie off and disconnected the harness so I could straighten the wires out. I then reintroduced a curve into the harness that was more gradual and the harness is closer to the heads but not anywhere near touching. I'm pretty confident you'll be fine.

Exactly how the dealership left it on mine after replacing the coil. No more zip tie and a curve instead of a fold in those wires. HD should consider changing their process in the factory to reflect this. I've seen several posts of the same problem on FB over the past week, now, and it's probably just the leading edge of the wave.
 
Whelpppppppp....I think this got me today. I clipped the zip tie a couple weeks ago after having the bike for only a month. 117 miles from the house, I'm deep in the carpool lane, 2000 miles behind me, day 7 of a road trip and I start feeling the bike lugging. Change in sound. Feeling that I can't really explain. Rough vibration. Slow acceleration. Veered it all the way from the left lane to the far right (4 lanes of Nashville rush hour traffic) and about 3-5 miles of limping it to a known gas station. I wasn't going to break down on the side of the interstate again. I'm not going to say anything about one dealership and how helpful they were. Called Nick at Moonshine though as I was about 10 miles away from them. He started asking around and no one could break free so I called HOG roadside assistance. Had a tow truck in front of me within 45 minutes of calling and the bike loaded in route to Moonshine.

They told me that they have been calling in at least 2-3 of these a week. Said it was the wiring. Texted @crazy4ink and his exact words "I believe someone that looked like me told you to cut that zip tie." I responded in kind, I did but I didn't chase the wiring to check to see if the damage was done. Now the bike is sitting in Franklin, TN while I'm home unable to complete my first road trip on the new bike. I feel like a failure. :cry::ROFLMAO:

Does HOG cover rental car expenses? Asking for a friend. lol
 
I’m so glad I did this when I first got mine. My harness was jacked up pretty good when I got it. Snipped it and smoothed it out. Checked the wires and pins/plug and didn’t see anything out of the ordinary but you never know

"Customer states..... I'm stuck on the side of the road..."

Damn Daniel.....sorry to hear Brother......now I am nervous about riding my '24 to NC for SW - Brad snipped my shit (metaphorically and literally all at the same time) and then straightened with s light bend (god it just keeps sounding worse) so hoping I don't fall victim to this
 
This really needs to become a formal recall.
That's what Moonshine is pushing for. They alert the MoCo with every warranty call they get on them. Seems that they are seeing more with the CVO's than the regular models, but still getting them across the board. Hopefully they will get the official call out soon.
