2017 FLSTC, 2,100 MILES. 2 minutes of warm up idling and this is the front header pipe. The rear pipe looks the same. Complete stock bike. This is ridiculous.

 

Both spark plugs connectors are properly plugged on?

 

Holy crap...mine doesn't do that

 

Been a few other people with this problem over the years I've been on the forum, comments range from its normal, the timing is out, running to weak, to rich. You've got a new bike so I'd take it back to the dealer to sort out.

 

+1 Back to the dealer...

 

Whoa! That baby is hot.my efi dyna
Would do that until I put a fuel tuner
On it.

 

Yeah, something is bad wrong with that thing. Back to the dealer for sure..

 

The dealer says it's fine. I will admit the picture actually looks hotter than in real life. I took it at night so the glow looks hotter.
yes plugs and wires are on tight.
I had a 2015 victory that done the same thing at warmup idle. I bet most of the new bikes do this. I haven't checked it frim a hot start, just from a cold start up after about a minute or so idling warm up. Not me touching the throttle at all.
guessing if the dealership sees it as normal, they've seen this before .
Wonder if they'd notice when I bring it in for a service if my cats "accidentally" fell out one day while I was inspecting my exhaust? Think that would help?

 

If that is normal, I would like to know what AFR the EFI is set is for running on Idle...looks like you are running really lean.

 

Now I'm curious. I'm going to run my bike til it gets hot enough for the EITMS to come on tonight and see if my headers are glowing.

That simply doesn't seem normal to me. If the dealer told me that I'd at the very least get a second opinion from another dealer. I have a tuner on mine. If mine's glowing tonight when I test hit, I'll call and get a tweaked map to fix it.

I'd get a power vision or fuel pak and tune it to run a bit richer if I were you. On a stock bike though, it honestly wouldn't really surprise me if this was normal. Those stock headers are so stuffed full of cat material with shitty air flow that it makes sense they'd get real hot.

but, check out this thread as it seems somewhat common:
