Had Jet-Hot in Oklahoma City coat mine to control some of the heat. Pipes were coated inside and out. Cat outside only. They did a very nice job. Helped with heat and changed the pitch of the exhaust to a more throaty note.Quote:

The tank could use the complete treatment to isolate it from the inevitable heat it's going to be subjected to. I've not been motivated to attempt that yet. We'll see just how much fuel I boil this summer. Might change my mind.
I have found fuel noticeably boiling in the RT tank on several occasions when I pulled in to fuel up after right after running hard on an Interstate. When you put the nozzle just an inch into the tank and it immediately shuts off (several times) you can be sure the fuel is boiling and spitting gas at the opening.... Usually doesnt last long and is not noticeable if you wait a couple of minutes before fueling.Quote:

Coating and/or wrapping the pipes has to be a good start and getting some serious heat shielding around the front of the tank should help.
It makes you wonder how they ever got the design approved for the positioning of the exhaust header pipes and tank.... This has to be the main culprit in the gas drip & fuel odors scenario too... Is boiling fuel common on other bikes ?
After seeing all this, my first mod on a new RT would be to take it apart and have everything coated and wrapped !
Will have to look into this... Maybe wrap the pipes and add some heat shields to tank.. :dontknow:
Thanks. Jet Hot is also in Burlington NC so shipping the exhaust there from VA shouldn't be too expensive. Plan on calling my dealer today to see what they would charge to remove the exhaust and reinstall it after the coating is done. Mr Orange had his pies coated at Jet Hot as well and is happy with the results. He had his down pipes coated with the 2500 degree ceramic and the rest with 1500 degree. Hopefully ceramic coating the pipes will cut down on the fuel boiling problem abd the glove box heat as well. I figured while the Spyder is all apart for the pipe job why not add some heat shielding to the tank as added protection.Quote:

Removed all of the exhaust components (left & right headers, cat and muffler) and had them ALL ceramic coated. Although they wern't done internally, just the exterior, I did notice some reduction in heat to the ridder. Did this a couple of years ago and am very happy with the results. Aside from the heat reduction, the muffler is much better looking than the stock painted surface. Have to warn you, removing and reinstalling the front and back exhaust headers is a time consumming job requireing lots of nimble fingers, 1/4" torque wrench, 2 universal joints and lots of patience. Oh, don't forget to obtain new locking nuts and gaskets for the headers. Don't know about others that have performed the header removal job but for me, reinstalling and torqueing the rear header was VERY difficult. You'd think the front would be the worse but that isn't, or wasn't, the case for me. Get er done.
HP Heatshield Mat from Heatshield Products is one product to consider. Rated at 1100 deg. for radiant heat. I've considered using this on the underside of the seat.Quote:

Thanks for the info on the heatshield mat. Have you used this product yet? Wondering if the self adhesive mat would hold up and how difficult it would be to get the gas tank clean enough to ensure good adhesion. Gotta do some research to figure the best heatshield product to get. Don't think this would work for the underside of my Ultimate seat since the seat pan is real rough on the underside, not smooth plastic like the OEM seat.Quote:

The only way, in my mind at least, to clean up the tank is to remove it so you can work with it. And as long as it was out I'd cover the whole thing. Overkill? Maybe.Quote:

There is almost no extra space between the frame members to add additional heat shielding under or over the tank. The shielding on the front over the rear exhaust header is the only place you could possibly add.
Well, there's the answer to that question! Thanks for the heads up!Quote:
