I was warming up by Fatboy this afternoon, letting the bike run at idle for about 20 minutes. I came back into the garage and both pipes were red hot. All the way from the engine to the cross over valve where the pipes come together. It was so hot that the chrome covers discolored. Any idea why this happened and what I can do to fix it? Thanks for the suggestions!

I am not an expert, but IMHO 20 minutes is too long to let an air cooled engine idle.

 

[Paniolo]

I'm no engineer, but I don't think it's a good idea to let these aircooled TC engines idle for 20 mins. If you want to warm it up, one min is enough.

 

[ViennaHog]

You can fry the engine by letting the bike idle that long. Other than that, warming up the engine during winter break is a bad idea as you never heat up enough to burn off vapor, acids and other nasty stuff that you produce during warm up. Do a search for 'winterize' or the like and you find some interesting views.

Good luck

Were you going riding or justing starting it up? As said, don't start a bike in the winter just to start it. Causes moisture to form. I to agree 20 mins seems like a long time. Obviouly it was if the pipes turned red.

Not this sh!t again.

Sorry...but I won't even comment on this one cause I might get barred. Smart enough to buy a Fatboy but...................

I'd have the ignition timing checked (if you have an adjustable module), but more likely I'd guess the idle mixture is lean.

I'll be blunt about this......... with the lean running (probably EFI, right) and letting the bike idle for twenty minutes??? You deserve what you got!

sounds to me like you might have a muffler bearing going out, a short fix would be to lube it. Not going to get into a discussion on what kind of lube to use.
if that don't help, you might consider a torqulson bearing instead of stock.

The Air cooled motor idled for 20 minutes and got way to hot. How about, buy some new pipes.....?

 

[Peacekeeper]

I've sat in hot summer Charlotte traffic for longer than 20 minutes and the only thing that ever turned red was my legs. To lean, give her some fuel....

You so funny GI!!!

Those ARE great bearings I've heard. The best lube is that new Henway grease.
