Wire harness & hydraulic line sheath melted
« on: January 28, 2012, 07:31:16 PM »

2011 FLTRUSE, Found the above melted the entire length attached on the lower frame rail, between the lower frame rail and exhaust pipes.  I don't know if it occurred while stock or after engine mods since today was first time noticed.  My cruise control light wouldn't turn on in the tach and won't engage.  I don't know if the two are related.  The fuses all look good.
I plan to take it to dealership under warranty.

Just wanted to know if this occured before, or giving you all a heads up.
Mileage under 6K miles.

Mods: Stage lll, Full Sac with X-pipe.  LED Lights on lower rail.

Have melted conduit, along right side of frame, but wires seem ok. Hydraulic lines are ok. I also have Fullsac x pipe, but find it hard to believe that the x pipe can run any hotter than the stock head pipe with a cat in it. I plan on wrapping the harness with foil tape and sliding a new conduit over it. Not sure what else can be done.

I'm sure mine had to occur with the stock set-up.  It ran very hot when the cats were in.  Now it runs much cooler.  I can see in some spots where the conduit melted right through and exposed the wires running through.  No damage seen on the wires.  The plastic frame conduit retainers, which look like zip ties.  Have melted off as well.

I only have a short melted section on my clutch hydraulic line, about a half inch.  It's the protective covering over the hydraulic line closest to the exhaust.

Thanks for responding.

You could use something like this DEI heatwrap:

Comes in different diameters.

Well I remedied my cruise control issue this morning by removing seat and readjusting connectors.  Had LEDs accent lights installed 10 days ago and most of the wiring was under the seat.  Last night I reinstalled all the fuses, no joy on that.

I have a new 2011.5 FLHTCUSE6 and noticed a burn smell of wires. I'm in Massachusetts so the weather is still cold and I only have 60 miles on it. The day I rode it was about 50 out. Our winters have been mild. What I did notice was that on the right rear side where the cross over is there is a plasitc conduit that runs along the frame to the front of the bike. From the crossover back to the rear of the bike the wiring is covered in a heat wrap but that's it. The conduit is wrapped with electrical tape. I can see the tape melted and heat has definately made its mark. I can just imagine a 90 degree day outside. I am going to keep an eye on this. I can see something bad coming here. They should have wrapped that with the sheilding mentioned above from summit racing. Harley does use that on it's wiring but should of also used it here. Those plastic conduits are very robust when it comes to heat so for there to be enough heat to melt that it's serous. again will keep you guys posted.

I was going to suggest using a similar wrap that we often use in the hangar on aircraft but thought it might be too expensive, until I saw what they were asking for their's!
Maybe I ought to charge a little more!  ;D

That wrap may not be needed yet. Its true I saw the tape curled up and heat stressed but I see no damage to the plastic conduit, wires or brake line. I have a friend who has a 2011 road glide standard and even though he has a standard RG he got caught in serious traffic this past summer and said his bike felt like it was going to burst into flames. He got the recall notice on the brake switch but has not done it yet. I remind him every time I talk to him. Told him if it goes it's bad. I will take a look at his conduit to see what it looks like and see if it's also wrapped with tape or is similar to bike. I guess one could always use Kapton tape. They are compatible with a wide temperature range from -269°C (-452°F) to as high as 400°C (752°F). This tape has a higher temperature rating than that summit wrap stuff. I would hate to think that exhaust goes as high as 500 degrees but I put a thermocouple on my 08 CVO Ultra and the temperature was high in that area but the pipes didn’t come as close to the frame as these do and with this current cross over more heat is concentrated I one area.

if the X pipe does start causing harnesses to melt then this issue is going to be very big because melting can turn into flames, especially on a hydralic line. I sure hope this doesn't become a major issue.

I would throw the BS flag on the dealer for this.  Many members run the x-pipe and I have not seen any report issues.  If anything, they would have a lower heat transfer through the sides of the pipe.

What they said.  Although I thought this had been corrected.   I would contact Steve at Fullsac.
