I'm thinking about painting the motor flat black - kind of like the ripple black on the Dyna Sport. It is possible on the XB? Any issues with heat, dissipation, gaskets, etc... Ideally looking to do top-to bottom. Thanks for the advice! | ||

Black dissipates heat better than any other color, that's why radiators are painted black. I don't see it being a problem, as long as you do a nice neat job. It'll look killer too! | ||

Your local Buell-H D dealer has the paint in WRINKLE or TEXTURE. It is made exactly for that application. | ||
| Kaudette |
tks guys. Aldaytona - do you know the product code for that paint? Also, is it spray on or is there a specific heat treatment that needs to be done - any ideas on the potential prep work? Thanks again! | ||

"Black dissipates heat better than any other color, that's why radiators are painted black" BS. Radiators in race cars are almost ALWAYS a natural aluminum finish. Radiators in most applications are not made of aluminum, but copper. They are painted so that oxidation doesn't occur. | ||

Rads are black , so the bugs dont show so much. | ||

the paint code for black is.... black http://www.hammerite.com/webapp/wcs/stores/HAMUK/Home/Jsp/Home_Page.jsp great stuff | ||

I would like to see the finnished product when complete? | ||

Iused a product "Gunkote" on my heads and other parts. really neat stuff, see the attached.http://www.kgcoatings.com/gunkote.html taken from the website ....when applied,"......Radiators, Oil and Transmission Coolers, to dissipate heat by 8% to 10% faster then bare metal while providing excellent corrosion protection."

I got everything Teflon Coated but went for the silver look...its also very dirty in the pics...sorry    | ||

"Radiators in race cars are almost ALWAYS a natural aluminum finish. Race cars don't sit in traffic." That's not the point... Black absorbs light and converts it to heat. This means that the Delta T wrt the dissipating surface vs. the ambient air temp will not be as great. Therefore... Black will not dissipate as much heat as a lighter color. If you have a radiator (or engine) that is NOT in the sun, then maybe you have a point, but when you place that black engine in the sun, it will be absorbing heat from the engine and the sun, and will not cool as well. Why do you suppose that an effective HP gain can be achieved by polishing the bottom of an intake manifold in a pushrod type american V8 configuration? You don't paint the bottom of the manifold black... You make it shiny so it REFLECTS the heat. Not absorbs it... Light and radiated heat energy are close to the same thing. Which do you think would get hotter in the sun... A Black wrinkle coated tool, or a chrome tool? | ||

Good points about the color on the radiator. I had always thought that was a little screwy reasoning. It makes more sense about the copper radiator being painted for cosmetic than function. I would also think that painted surfaces cool less dues to the fact that more layers for the heat to escape thru. | ||
| Glitch |
Either way, I'd bet a black painted air cooled engine would dissipate heat, rather than accumulate it. | ||

Which do you think would get hotter in the sun... A Black wrinkle coated tool, or a chrome tool? The black one heats up quicker, but also cools down quicker. Why do you think nomads in the desert have black tents and clothes? Black dissipates heat faster than other colors. I doubt that the application of a black radiator on a buell would make that much of a difference though. I think looks are more important here. | ||

You're correct about the radiator... It's fairly small... "mostly" blocked from the sun etc. The block however is NOT blocked from the sun. Ingemar... Take a look at CNN when they are getting footage from Iraq. The Iraqi's don't generally wear much black. Glitch... Of course a black painted engine would dissipate heat rather than accumulate it (although it HAS to accumulate in order to dissipate) but the Delta T between the surface and the ambient air temp will be smaller. Therefore, the ONLY thing a wrinkle black coating has going for it is the extra surface area. I don't believe that is enough of an advantage. I think that if it was, Buell would have blacked out the engine to begin with. | ||

Very interesting thread. Ingemar's correct about Bedouins wearing black. It's very common to see a white Thobe (that's the long gown looking thing) in white cotton. On top of that they'll throw on their Bisht/Aba and that's normally, but not always, black cotton. Pure observation -- not a hijack attempt. | ||
| Glitch |
OK, I give. I didn't pay enough attention in school to argue the point. Either way I look at it, I won't hesitate to install this...  Bigdaddy, If it were me out in the desert, I'm not entirely sure the color of my Bisht would be the important factor | ||
| Bigdaddy |
For the most part if you're observing Bisht clothing you're on the wrong continent. The disclaimer to that would be LAX & EWR -- no shortage in either location :-) | ||

That's the thing... I think it's mostly a cosmetic thing. Either way will only lead IMO to a small percentage of temperature change and quite frankly, the hotter the engine and cooler the intake tract the more power you will have. I think if you're looking for the "best" coating for thermal conductivity and dissipation... Use Copper, Silver or Gold in a wrinkle coat. Not the color. The element. | ||

my side cases are black powder coated...glossy black, easier to clean than a flat black or wrinkle......I would like to have all of my cases black..and will do that when I have to split the cases....remember the vincent had black engine cases, glossy, and looked great. REX | ||

That's the thing... I think it's mostly a cosmetic thing. For the radiator, yes. For bedouin tents, no. For our military clothing I think camouflage is more important than absorbing or dissapating heat. One little experiment that you can try is with a 2 wing propeller that rotates freely and smoothly. Color the front of one wing white, the other black. On the back of the wings, invert the colors so that the white wing is black on the back, the black one white on the back. Hold it in the light. With a little luck it will start to rotate . | ||

Call KG Industries, 715 934 3566 ,talk to Joe Fazio. He tried to get Harley D. to to use his coatings.For what ever reason they did not. Probably not pretty enough. Do not use a gloss, powder coat on parts that need to expell heat.Funny my leather jacket(black) never gets hot to the touch riding in the hot summer Mid West blast furnace but if I ride without it I feel like I absorbed alot of heat after I stop. | ||

Black transmits heat faster. ( in and out ) The thinnest insulation is best. Thick film wrinkle black is not so good. Powder coat is not so good. Gunkote, black anodizing, both are very good, better than bare metal. Come on, this is simple physics, not complex like counter steering.. ( sorry could not resist ) Happy Solstice. |
