Looks MUCH better than stock IMHO!

Did you have it coated, or is someone already making a replacement?

I like it too!

Sleez,
The heat shield on the pipe is silver for the OEM configuration.

They changed the small black heat shield to a significantly larger one after the hot foot issues. the production shield is a bare metal/silver color. To me it looked a bit out of place.

I know black gets hotter than a silver shield (possibly the reason it was left silver.) Ceramic coating not only stands up to heat better than powder coat, but it also has a anti-conductive property, which I hope counters the black issue. We will see.

Cost was $25 plus a $5 hazardous waste fee. That is a walk in price with no connections. Remember this is a ceramic coat not a powder coat (which is cheaper).

what was the turn-around on it?


now someone needs to buy an extra one so they can get that coated, then sell the stocker to someone else to get theirs coated etc etc etc then no downtime!

ill call about that tomorrow actually, see how much the stock piece is

can you give me the dimensions of the shield? approximately

>>>I know black gets hotter than a silver shield


That's half right . . . black also gives up (radiates) heat much faster. Although black "attracts" ambient heat, say on a sunny day, that's a small part of the heat you have to deal with and reflecting it (with shiny or white) away does little to change things.

Black on the other hand does a superior job of radiating convective heat.

PERSONAL OPINION of a construction worker.

I used flat black bar-b-q paint, good to 1200˚F.

Whatever method, it looks tons better black than stock.

I installed a heat shield on my XB9S.
Due to the conductivity of the aluminum connection it got very hot.
I wrapped the pipe completely just under the shield.
I can now touch the shield, it's not too hot.

That's a great idea about putting some wrap under the heat shield. Should be hidden well...

Garrett, I have no complaints about heat, but it is the middle of winter. I suspect it will possibly become an issue in the warmer months. Hard to answer your question.

Yes there is a problem with heat temp. on the brake (right) side. I was at a back to the track at Road America that my local dealer sent some customers. Buell said they had a fix. The track bikes were all pre production, with a black heat shield. My front right boot got very hot. This was sept. in WI! about 75 to 80 or so great day to ride the Future of Sport bikes!

I first painted my heatshield black inside and out.
That proved to be a mistake, as the shield gets almost as hot as the pipe.

I took it off, removed the paint from the inside with solvent and coarse bead blasted the outside.
Then I polished the inside on a cotton wheel with rouge till it looks like a mirror.
Took it home and painted the outside flat black again.

It still gets hot, but not enough to slough off flesh on contact like the header.
It cools off much faster now though, since it is absorbing less heat than it radiates.

That is a good idea, Zac. If it becomes a problem, I might do the same. It would be nice to get some temperature checks with:

coolant temp
ambient temp (not thru onboard reading)
heat shield temp
header temp

Maybe we can determine what is working and what isn't...

My friend has a infrared thermometer that I will use as soon my bike finds its way over to his shop.

With what I saw this morning - it was about 40 and I rode about 12 miles.
As soon as I got off the bike, I pulled my gloves and checked the heatshield.
It was too hot to touch for more than a second, meaning it's over 140, the top half sizzled spit, the bottom half did not.

I think I'm going to try heat tape under the shield next.
I believe it was "Old_Man" who I saw suggest that. D'oh yup only a few posts above, forgot it was this thread...
Although it's cooler than before with polishing, I'm afraid it will still be too hot in the Summer.
Perhaps thermal insulating washers between the shield and the header, but Stainless conducts heat about as well as a turd, so I don't know how much help that would be.

More R&D -

Zack

Fellows ,I went ahead and solved the whole problem with the looks and heat of the pipes..... I just wrapped them. My stock header looked like a pigeon shit on it and took a torch to bake it in. I wrapped from the split to the muffler including under the shield. Much less heat and everything's black ,except for the shield since it matches the rear brake lever. I thought I'd save time and do it on the the bike Bullshit!! It was really hard trying to get in between the two pipes right before the muffler. The effort was worth it and I'll post some pics as soon as I can.

Here's the headers wrapped, way cooler now and I can cover the bike as soon as I get home instead of waiting 20 min. for the pipes to cool down.

I like that Blazin...now you may want to consider painting that shield black. Tell me why do you have to bake the pipes first?

No, the pigeon baked HIS shit on it with a torch. It looked that bad after a couple hundred miles.

Gotcha. You are right, there is some splotchy discoloration. I think I'll wait until the weather warms up for possible header mods. Right now the warmth is actually welcome!
