Engine heat shield

[FMFTLR]

I've been playing around with the idea of adding a heat shield between the rear of the motor and the frame in an attempt to keep my testes from roasting! Anyone else try it yet? My main concern would be trapping in too much heat around the motor and either a.) starting a fire! or b.) melting everything in there!

Any thoughts?

I've got other ideas I plan on trying in the next 6 months or so when things slow down for me.

I'm in the same boat, but it's stil in the "ant to do" stage. There was a thread on her or [the other site] with a picture of a home built heat shield. If memory serves, it was on a TLS. The owner made a shield covering the exhaust from the head down into the swingarm.

Plans here are the same, perhaps piecing together some scrapped cruiser heatshilds or the OEM heel plates from a Ducati Monster. I am even considering adding a fan beneath the rear fairing, maybe something from a Buell or Beemer. The heat shield is the desired solution.

Several members have used fabric exhaust wrap to minimize the undernut temps with great success. I can't imagine that getting the wrap into the spigot area would have been easy, not mention that the exhaust already sits close to the belly pan without the added diameter of wrap.

There is also a manufacturer that made some shields for the "gap". It doesn't change the temperatures under the fairing, but keeps legs a little cooler. Once again, I don't recall who that was.

I'm going to have my pipes thermal coated. Gives a better finish look and don't have to worry about moisture getting under the wrap and rusting everything. The other thing I was thinking might work it covering the inside area of the frame with reflective insulator. Or could try DEI's insulator.

Here's the stuff for auto/moto applications:

DEI is auto as well and you can get that cool gold too!

Re: Engine heat shield

I was thinking about aluminum heat sinks that would run along the frame rail under the tank. It would add some "look" to it, but still be out of the way of your legs. The other thought was posted on Van's thread of the c/f frame covers, having them kind of flare out just under your legs to keep your legs from burning on the frame. That's the only heat issues I have is when stopped and your legs are down.

Re: Engine heat shield

what about just wrapping the pipes?

Re: Engine heat shield

I am a TLS owner and have never had this problem so does it apply to TLR owners only. Mind you I am now considered to be an old bugger and the family jewels have not been tested for awhile.

I'm sure it would help, but not sure how much.

As far as I can see, frames are different between the bikes and fairings. Most pics of TLS's show half fairings compared to full like on the TLR's. So, from pics, I'm guessing the TLS's have more air flow to keep said area cooler. Just my thoughts.

Re: Engine heat shield

That and the TLS frame isn't solid like the TLR. And as for wrapping the exhaust pipes, you could do that or ceramic coat (it's kind of like powder coating with heat resistant material) Either way the goal is the keep the heat from radiating off the exhaust pipes.
