insulating under the gas tank??????
« on: August 02, 2014, 02:20:10 am »
I am thinking of insulating under the gas tank of my 09

I saw some bubble  / foil insulation at Lowes it is primarily used in attics.......will this do??

anybody else done this???


looks like I can unbolt the tanks and prop it up and fit the foil in without disconnecting the lines or wires

Thanks for the input

Haven't done it on my '08, but I did use it on a new replacement C10 tank that didn't have the OEM heat shields. Just be sure to get the aluminized tape that is used for sealing air ducts in buildings. Don't use any other tape, it won't last. The tape should be next to the insulation.

Or, just go to Ron Ayers or BikeBandit and order the OEM stuff. About $17 a panel, 4 needed.

I use that stuff to cover the windows in my trailer when I go winter camping. It works well installed on the inside, but from outside, my trailer looks like a big baked potato.   :rotflmao:

I used the silver bubble insulation like what you would find in a sun shield for your vehicle windshield. Might have helped some but the tank still gets hot on a hot day and hot air blows out between the seams. All of my OEM heat shields are in place.

I've been looking for thin rubber sheets to put under the tank and try that.

I built a window shield for my drivers door on my full size Bronco. I can tell a difference in inside temp when the sun is on the drivers side and I hop in.

I used the foil backed auto insulation that was used on some under carpet areas and firewalls. It gets danged hot on top of that motor, I didn't want anything with plastic or rubberish padding to melt.

You can use the silver metallic bubble style sun shield for cars with no melting issues.
I cut mine so it covers the gaps between the tank and side covers and under the glovebox.
This with the side shields in the lower fairing made a huge difference in radiated heat on the first gen.

Dynomat works but it is damn expensive. If you ebay automotive soundproofing, you will find a much cheaper alternative, but does the same thing . It also creates a nice heat insulator. Has a self sticking back, so is easy to install. For soundproofing, I did my whole Maxima...doors, floors trunk, and it cost me less than $50. Dynamat would have been closer to $300.  I also used some leftover to help keep my aftermarket horn, and lockbox on my C14 a bit cooler.

Eastwood has a product also. I kinda like the Ebay pricing though.

If you're appling a Dynomat type of product, are you applying it to the underside of the tank or to the area under the tank?

Yup, that's the stuff I used - Radiant Barrier, typically used in homes to insulate attics and crawl spaces. It's an aluminized bubble wrap.

25 bucks for those two little pieces? A 75 yard roll goes for about 70 bucks.

Pope, I would adhere it  to the tank. It will stay anytime you lift the tank.

That's what I was thinking (reflective foil facing the heat source), but wanted to know how others did theirs.

I used Reflectix > think I got it at lowes. A roll is about $25. Worked great and it will mold around the shape of the frame if cut right. I get no heat from my tank now, even in +90F temps. I would recommend you completely remove the tank. You want to take your time and not worry about the tank falling or getting in your way. Net time I am doing work on the bike and have it apart, i will take a picture.

I bought the same stuff you are talking about...from Lowes. It sunder the tnak of my 08.  Did it help???  Well....

Prior to that, lets go back to the new bike. I loved it, btu disliked the heat on my ankles/feet. I bough the rubber inserts to block that (ebay).  They worked, but trapped heat under the tank...so, the Lowes stuff was added...

It might have helped a little, but I''ve realized this bike makes a lot of heat, and it has to go somewhere. Removing my radiator guard helped overall. 

I dont know if any of the heat fixes really fix. I believe they more or less move the heat to somewhere else.

Its easy, and cheap, so try it....but I'd nto call it a fix.

I just applied an automotive heat shield material to the underside of the gas tank. It's a heavy gauge aluminum foil with adhesive - probably 1/16" thick on it.

It definitely reduces the temperature of the gas tank. Prior to applying this stuff, I found the tank eventually was too warm to comfortably grip with my legs.

Of course the heat that no longer goes into the gas tank has to go somewhere. I've noticed the temperature gauge seems to rise sooner and the fans are running more often than before. I expect that's unavoidable.

I purchase under tank insulation I found on eBay for $25. Precut and it has worked pretty good so far on my 2008.
Before the tank and lower panel was so hot it would cause discomfort to your legs. The insulation covers the upper frame area and the seam where the side panels meet the tank. Rode 200 miles yesterday in 90 plus heat and it was awesome.
No hot legs and tank didn't get too hot. I think in the future I will cover the bottom of the tank in firewall insulation  and install the lower foam inserts.
