OK, so after a couple of members on here have doubted what others have came to realize was the truth. This photo was taking on a 50 degree evening, ice cold engine. This is what just 5 MINTUES OF IDLE TIME DOES TO THE EXHAUST. THERE WAS ZERO THROTTLE AND THE VIKING DID NOT GET MOVED. Just idled from a cold engine in my garage. Tell me this, there is no safe guards here to keep a child or anyone for that matter from accidently placing their hands on this extremely hot surface. I see a law suit in the future if YAMAHA does not get their heads out of their A$$. More pics to come with HEADER WRAP
INSTALL.
NOTE, I urge all owners to verify the steps above if any more doubt should surface.

That is normal for a stainless steel single wall exhaust on any four stroke made in the last few years. These engines are designed to run lean to pass all emission standards. The warmest the exhaust is going to get is for the first little bit of start up when the engine is running leanest because more air is supplied to the engine for cold starting. I had a wr450f and a TTR250 that would glow in the night time like that and my ttr had over 18,000 miles when I sold it.

Oh yes I agree with you there they could use something to help protect users/equipment from the exhaust.

OMG! Whats done to keep a child from any motorcycle exhaust or engine head, or lawn mower muffler, or a generator muffler, or tractor.. I cant believe what Im reading!

How about this.. Keep an eye on your kid, and dont let them touch hot machinery!

Lmao! 'or anyone'? From placing their hand under the bed, and touching the hot exhaust? Sheesh!

Never mind I give up. Clearly the main reason for this thread has been missed or just not a concern for everyone. Rear differential excessive heat. I'm done

Thats not what you said.. You want to have Yamaha get their heads out of their ass because someone could touch the hot exhaust, and your talking about law suits! Your post and thread is ridiculous..

Yes, it may have been a little excessive but never the less, my thread does have merit. I was trying to get the point across that, not only would the rear differential benefit from a heat shield, but from a safety frame of mind that the exhaust pipe is wide open with nothing to block it from being bumped into. I know I am speaking from my own personal clumsy experience that, I could see myself one day being back there to slide in a receiver hitch, and my forearm bumping into that. Little off topic here but, when rhinos first came out, they didn't have any type of doors on them. A person was in a bad area and was turning over, this person stuck his leg out to stop the rhino from turning over. Guess what happened next, he got hurt, he sued, and rhinos came with doors from there on out. Granted it wasn't a smart thing to do, but apparently someone agreed with him that Yamaha was at fault to some extent.

Im still not getting it, and crying law suit just gets under my skin. Its a hot exhaust pipe, just like climbing under your truck a grabbing the exhaust pipe by accident while changing the oil doesnt mean law suit. I also see no way to bump into the hot pipe because your sliding in your receiver hitch. And if you do, witch is next to impossible, you wont ever do it again after your first burn.

These past couple of weeks I have been keeping track of outside temps, ride conditions, and diff temps. I am going to do some more riding before I post my findings, on the before and after header wrap temps. I am also thinking about a less restrictive exhaust.

I wonder if the factory muffler is causing a lot of back pressure? I took out the spark arrestor just to see what the guts look like. Doesn't look like it would flow to good.

My question, is everyone's doing this or just camo2014. It might be it needs to be checked by a dealer to see if it's running to rich or lean.

I have another thread on this with 4 pages of posts. From what I gather it's normal for this thin wall exhaust pipe to glow red like this, however my main concern is, the rear differential is getting extremely hot, like 250f plus in some cases. Under normal riding it stays under 200f. The seals on my diff is already leaking and I'm certain it has to be from the excessive heat. Granted I know that it's normal for differentials to get hot, I drive a truck for a living so...165-200f. All day long gross @ 124,500lbs

I've seen pipes turn color before from the heat and that's normal but to have them glow red is usually a sign of something no right with the motor. I seriously can't believe with the problems/law suits Yamaha has had in the past they would let something like this get by. It just doesn't look or sound right to me. I'm going to call my local dealer tomorrow and see if they have heard of this.
