Is there any advice to prevent the rusty muffler? Has it been fixed on more recent models? Is it rusting from the outside or the inside? |

Just remember, parts are going to fail. That's a fact.
I work with computers and I am constantly telling people not to put important data on their hard drives since it's not backed up. It's not a matter of "if" a hard drive will fail, but "when".
That being said, I've seen some last so long that they eventually become too small and are replaced. I've see some last a month. All the same design. |

I have a theory that the BAS relocation is because of the old locations proximity to mucho heat. Further, lots of vibration exists in the old location. This, coupled with seat pan deflection when hot, is the cause of the ECM failures I've had. Come to think of it, a battery's worst enemy is heat + vibration, isn't it? Maybe rather than relocating the BAS and other components, controlling the heat, seat pan and vibration is the better path.

Send it to HPC or Jethot and get it ceramic coated. I used HPCs 1600 degree black coating. They charged me $55, which I thought was a great deal. I spent more shipping it than getting it coated.

Can the inside of the muffler be ceramic coated if it is a used muffler? Seems like it would not work well if it is goes on dirty metal. Maybe they can be cleaned. |

Alchemy - I don't think they can do the inside of a muffler, but I don't think a dirty muffler is a problem either. Mine was used, with dirt and rust on it. They have to blast off the paint before they coat it, so cleaning the part up is a standard part of the process.
Notice how clean the exhaust opening is. I don't know how they cleaned it, but they did a good job. |

Thanks for the photo. I wonder if they sandblast them first. |

You can call and ask if you like. I contacted both Jet-hot and HPC. Both were very helpful on the phone. |

Alchemy.......I use Gibbs penetrating oil on my muffler to keep rust at bay.It works.I live at the beach,plastic rusts here! |

Dfish - Does it smoke when the muffler gets hot? |

Looks like they coated the inside of the outlet at well.
No smoke from coating. I have my header coated, and they do inside and outside on them. |

Just the first millimeter or so. The metal inside the outlet is white. It was of course coated with carbon when I sent it in, so whatever they did to clean it up cleaned up the outlet as well.
The coating apparently sprays on. If you look under the heat shield on the outlet, you can see the same bare white metal there. I suspect the reason they can do inside out on headers is because they are open on both ends. I wanted to get my headers done, but you have to practically disassemble the bike to get them off. That intimidated me too much. |
