Man! It's HOT down there!!

[DaveH]

While prepping my ST for a trip to Colorado next week I took the fairing off and this is what I discovered. Hmmmm

 

[justin_sabre]

might want to see about wrapping the header pipes so it wont be so hot down there,

Put some reflective aluminum foil tape on the panel to protect it from heat.
We did that for years on two cycle snowmobiles that can have exh temps up to 1350 degrees.

As stated I would insulate that with some aluminum foil to deflect that heat.

That isn't supposed to happen. Wrapping the pipes will remove the symptom but not the cause.

You may have a cylinder running lean because of an intake leak or ignition problem (bad wire, bad plug, wrong gap, etc.). Remove the fairing, run the bike up to three bars and measure the temperature of each of the exhaust pipes. If there's one (or two on the same side) that are different, you have a problem.

Yes indeed, it do get hot down there. I don't think my tip-over covers are in that shape but I know from the melted plastic in the picture of my RH knock sensor that it gets a tad warm down there:

There's metal heat shields on the later year bikes. I know my 06 does.

Dave, it looks like you're showing pictures of both side fairings' inside surfaces, below the tip over covers being blistered from the heat? (Fred, '04 and later have the radiant shields inside the lower fairings, not on the inside of the side fairings.)

That's a lot of heat! I'd check the knock sensor wiring / connectors. Any mods to the bike? Do you get caught in stop and go traffic in the heat? It is suspicious that the exhaust pipes are getting that hot on both sides of the engine (or did one time).

I'm thinking probably from letting it sit while running it. Hot day and no air circulation! 4:

I'm not sure when the blistering occurred, but I'm thinking that it may have happened when me and Li'l Bro (SupraSabre) took a quick trip to Oregon last year during the hottest days of the year. When we went thru Redding CA it was 117. At any rate I'm thinking of making a couple of heat shields out of sheet aluminum. I'll be pulling the plugs today to see if there is a problem there but the bike runs really well so I don't think there is a mechanical problem.

I should have looked more closely at the picture. I thought it was the lower fairing.

Obviously a case of global warming!!

 

[jmcarruth]

My bike is a '03 with no heat shields on the fairing. It has never gotten that hot, even in the AZ desert with the outside temp at 112 degrees F.
Something ain't right. Not sure what, but I would suspect some sort of fueling (lean) condition.

I need to be more careful reading thread titles.... I thought you had a religious experience with a vision of somewhere warm!

He was in the US Army and National Guard for 20 years, I'm sure he expericed a few of those places!
