This is the material that I found to make a extra added heat sink for the R+R

The picture is not great but I drilled holes and bolted said piece to back of R+R on the relocation bracket. This should act like a extra heat sink to help disapate the heat and help keep the R+R cooler. What do you think

Also used this materiel to make my own floor boards

Looks cool and should work well.

Quite awhile ago I sent some of this material to Hizzo to do the same thing. Don't know if he ever did it or not. :confused:

Where can I get this material? and what did you cut it with?

Great idea. let us know how it works out.

I guess maybe I'm having a bad day here, but....

why is adding an aluminum plate to the back side of the r/r a better idea than just letting the r/r drop heat to the passing cooler air?........:confused:
Just adding a piece of 'plate' aluminum wouldn't be of much help.
You need cooling fins of some type to help dissipate the heat from the R/R.
There's already fins on one side, so adding some more on the other side will cool it that much better. And it works best if the surface of the R/R and the surface of the finned aluminum material are making as much contact as possible (as in, both pieces being as flat as possible)

Kind of like the fins on the radiator. Ya don't really need them, because you have the tubes filled with coolant that have air going past them, cooling them down, but with the fins, it works much better.

Does that help ya understand the idea any better? Or just make it more confusing? LOL

I think you guys are onto a good idea (sort of). I doubt there's need for any more cooling once the R/R has been relocated, especially since it's away from the exhaust crossover tube.

If I were adding the aluminum extrusion to the back of the R/R, I'd mill the back surface of the R/R flat so that there is as much of the R/R casting in contact with the flat side of the extruded plate as possible. Then I'd slather on some heat conductive silicon grease before bolting the two together.

Good luck and post lots of pictures.

A plate itself would do know good. However what they are using with fins acts as a heatshink. Basically why this works better than just passing to the air is because the heatshink "pulls" the heat away from the R/R before it can truely over heat and then the heatshink dissipates it to the air.

Would it work without the heatshink. Yeah sure. But the heatshink will help it last longer, besides it looks kinda cool.

Go to the elecronic store and pick up some dielectric grease. It bridges any noncontact areas and transfers heat. Never used it on a weather exposed area and would be curious how it worked. before washing out. A lot of high power heat sinked transisters use this in addition to a heatsink.

The fins on a heatsink (or radiator in hyper's example) creates more surface area. With an increased surface area you allow more air to pass across it and dissipate more heat. That's why there are already fins built into the R/R. Adding more fins creates more surface area. Kind of like the heatsink on your processor.

just a cumputer cpu fan on the r&r works for me

Ok. who's up for a contest? PIMP your R+R.

1. heat sink (shape, how is it attached and etc)
2. fan (lots of choices here) Mine would be solar lol
3. lighting?

Mine would have VN750 logo on it.

...Or how about making the wires long enough to tape it to the top of our helmets. :doh:
