This just seemed odd to me, let me know if I am off here.
Last night - yes well after dusk I was tinkering with my CRF450. Been having Carb issue.
I button it up turn on the gas and kick it over. All is well. Choke is on and I am running a high idle. I turn the choke off and examine my work. Something is still wrong because I have a midrange bog.

So I light it up again with the choke on and wife points out that the header pipe is glowing. I nod that is normal. I have seen it glow before. So I look down and the glow is going from the head where it bolts up to the leg guard about four inches down the pipe.

So - Normal? Usually I run it during the day.
Stock titanium header pipe. The only thing I have changed is put the stock tail pipe back on from the FMF I had.


It was really pretty.

My buddy was working on his yz450 and his mega bomb was bright red, it was cool, I used it to warm up my burrito.

It's normal. When I saw this on my old 450 one early evening, I freaked out and thought something was terribly wrong. Then I did some research...

Yeah man... perfectly normal... my KX450 glows bright red as well. And as I learned the hard way.. gloves dont always help when you attempt to touch.

It was about the same as that. I knew it got red at the tip, I was surprised to see it glowing as far back as it was.

I was wondering if the stock tailpipe being on the bike caused it. Its still jetted for the FMF. Just remembered that. Would that cause the bog in the middle?

F1 and Indycars use inconel for their headers. It is lighter and can take more heat than titanium, but ultra-expensive.

There is a local shop here in Indy that makes nearly all of the IRL headers and also TRD's NeckCar headers. The guy who runs it is a big dirt bike guy, and he told me he'd like to do inconel pipes for dirtbikes, but the investment is so much for the tooling (they actually roll the tubing out of sheet) that he can't afford to take the risk of buying it without really knowing if people will spring for the pipes.

While the inconel sounds really cool and I am sure the majority of track rats that .01% (that has the new bike, new rims, ti exhaust, graphics, new gear) would have it, I think $150 on sale for the headers we have access to today is too much. I can get a set of headers for my truck for $180. Its got 8 cylinders. Bike 1. I can only imagine the price would be $600.

Mine doesn't glow like that. My pipe is much bigger and shinier than that though. Smile

I saw a Yamaha Banshee 350 twin at a half mile race one nite with both pipes glowing cherry red from the cylinder to about 10 inches down the head pipes. It lasted about four laps till it seized hard and ejected the rider nicely. The plated pipes looked like they had just come out of a kiln.Laughing

Some F1 teams build headers out of .012" inconel. Thats almost 1/4 the thickness of most Ti MC headers.
Strong stuff. Becomes nearly transparent at certain temps.
Somewhere there is a Vid of an F1 motor on the dyno and at certain RPM (probably way down around 14k) you can see what looks like bright rings moving through the primary's.

In a word: no. Inconel has a melting point of upwards of 2300f. The pipes on those engines only reach less than half that temp.

When I was at Riley, we sold inconel headers for the GrandAm Daytona Prototypes for about $10,000 a set.

Stainless were $6500
