Idling for a minute, stainless headers and Euro 4 does this.

Had this on many bikes, Ducati, BMW, Suzuki.

Looks horrible does it?

 

I’ve owned Harley, Honda’s, Yamaha’s, and suzuki. None of them did this. I know the exhaust gets hot, but this just doesn’t seem safe.

 

I would call your dealer and let them know your dilemma. We had another member here that had a worse issue. It seemed to go away as the engine broke in.

 

I plan on doing that tomorrow before work. I have a warranty and not too worried about it as long as it gets fixed.

 

100% normal
I spent an entire week on customers 2014 chieftain.
Took his bike home at night and replicated the same thing
I checked every ignition component, checking every fuel component, even swapped out head pipes thinking maybe it was weak pipe.

End of the week took home a brand new 2017 1mile chieftain and did the same thing.

I bought a brand 2106 chieftain, head pipe did same thing at night.

Even talked with Polaris head technical guy

Wow...that seems hard to believe. It’s right under the gas tank and rider. Call me Hell Rider when I burst in flames...lol

 

The hot exhaust can be at least partially fixed with a better fuel tune profile - need an added tuner either PCV or PVCX. Either will be well supported and documented here. My first Chieftain would get hot like that if left idling for any length of time at all or if stuck in very slow traffic. I removed the stock exhaust system and did considerable tuning adjustments to that bike.

 

Yes they are def on the lean side for emissions

My bike does it too. I just don't look at it... That's how mine stopped

 

Yfz400 run so hot you can see through the pipe when letting idle to long.

Go ride your stock bike at night, stop in a dark area let it idle for just a min or two
The pipes glow

Fwiw don't spend a bunch of money on a tuner to fix it. It won't. Even the pcvx with a fuel Moto tune doesn't fix it. It's a normal thing on these bikes. I'm thinking the head pipes aren't thick enough.

dont do much night riding but will see if mine does this, tomorrow night! damn! that aint right

 

My dad, who was an old Indian rider, used to tell me a story about the old inline Indian 4 cylinder bikes. He would say, at night, riding hard, that the rear 2 cylinders would get so hot, and cherry red, that you could almost see the shadow of the pistons going up and down. I can't vouch for the truth of this story, but my dad, who was a genius mechanic, was not prone to telling wild stories.

 

Remove the CAT and get the pipes ceramic coated, that will help alleviate that problem. Worked for me on my 2017 Springfield. Before these changes, I could see the cherry red rear pipe in the daylight when parked in my garage.

 

Who coated yours? I had mine coated and mine still glows a little.

THIS JUST AINT NORMAL!! YOU SHOULDNT HAVE TO REMOVE THIS OR ADD THAT, I DONT GET IT, JUSAYUN--- ill chill now

 

I agree 100 percent. Not on a 30k bike

 

That doesn’t cool down the gasses, you just don’t see it anymore ;-)

 

I believe, as the engine breaks in, the color will tone down. The engine is factory tight, so the tolerances are still tight. Just my opinion.

 

25k miles on mine. Still does it.

 

This...is totally normal.

About the only thing that changes during break-in is bedding of the piston rings to the cylinder wall....

Which should happen quickly and firmly. If these aren’t (properly) run in yet you have more blowby.

I got no clue how this could tone down the temps of the exhaust -gasses- over time.... maybe the ECU adjusts itself?

 

ive used cutting torches a lot in my life, and when steel gets that HOT you throw the oxygen to it and it cuts!! blows it away

 

I believe it’s a safety issue in regards to a piece of clothing touching it while riding, or even refueling the bike. To accept that this is normal doesn’t sit well with me. Not to mention that steel will most likely crack from vibration or hitting a bump, causing more serious problems.

 

Just do a google search on “motorcycle headers glowing red idle”....

 

Cheap a** thin exhaust pipes.... The reason you don't see most other bike 'glow in the dark' is that they are high quality double wall exhaust pipes..... pipe inside of a pipe!
Did I say cheap, they're not cheap they COST a LOT? They just didn't cost much to manufacture!
Blame the bean counters!

 

And the lbs counters...

 

I’d dump the thing and buy an electric bike...that is if your not afraid of getting electrocuted riding in the rain, lol

 

Exhaust headers turn red in the dark. It's not because of cheap metal or lean fuel mixtures. Steel looks red in the dark anywhere between 400 - 700 degrees F, which is well with the normal range of exhaust gas temps at the head.

It is not because of lean conditions; if anything, it happens more when the mixture is too rich and there is still some combustion going on in the exhaust stream.

By the way, uncompressed gasoline auto-ignites at about 535 degrees F.

I would have to agree with this. This is something I have had since day one. I bought the PVCX and tried both the fuel moto tune and the dyno jet tune but it still glowed red around 60mph in 6th gear just above 2k rpms. If I throttled out of that range the glowing would stop within 10 seconds or so. Since I had the glow stock and with the tunes I proceeded to just drive it. I did some tuning with the powercore and craigs equations and it lessened some but not much. Fast forward about 2k miles and I checked the exhaust gasket. It was leaking. I changed it and it still glowed red but not quite as much as before.

Fast forward another 2k or so miles. I continued to tune and adjust the VE tables to finish my tune. It still glowed red. So I continued to just drive it and not worry about it.

Fast forward to 2 months ago. I decided to start all over from scratch since I know I had a exhaust gasket leak. I retuned using craigs equations and the base fuel moto tune I had used before, and did 5 corrections on the VE table and 1 correction in the IPW and decided to give that a try as it ran pretty good. Low and behold I have no red pipes glowing (actually it was just the rear pipe for me).

I hooked up the PVCX to get the % load at my 2250 rpms and 60-62 mph and it is around 30 to 35%. I tried to correlate that with the VE table in the dynojet software but I cannot figure out what inHG that correlates with. My VE tables appears to have leaned most of the column at 2250 rpms from the stock and FM tunes squashing my theory that it was just too lean at that load setting. Having too much fuel somewhat makes sense to me but I am not sure.

Thats my story, thought I would share.

This is only a suggestion,but usually,if ya have a header pipe that glows like that,you have a restriction in the exhaust system.Did ya check the mufflers for any nests that may have been built by critters over the winter months or,if the bike is parked outside and or near a wooded area??? Those critters can and will get into anything and build a nest.So ya might wanna check your exhaust for nests or even a critter that got trapped in there and died from the heat.Follow me?? Dave!!!

 

(It's a new bike)

 

Sidenote: I bet every one of you knows more about engines and exhaust systems than I do, but it's both amusing and concerning to see so many polar-opposite "expert-sounding" opinions on this topic (and others on here!).

 

So far we’re up to exploding gas tanks, rodents stuck in pipe, too lean, too rich, normal to outrageous. I’m waiting for someone to blame the Indian oil.

 

Well I took the bike in to the dealer and they said that they have never seen them get that red and that they would fix it. I’ll keep you posted.
