#200557 GaDawg (User) Fresh Boarder Posts: 8 Exhaust Discoloration 2 Years, 11 Months ago   On my 2007 R*, my bottom exhaust pipe has got a patch of bluish rusty discoloration where the small pipe joins the muffler. Anybody else seen this? It almost looks like hot gases are leaking out of the joint.   Logged     2007 Yamaha 1700 Silverado Hamilton, GA   The administrator has disabled public write access. #200563 cdrprn (User) Expert Boarder Posts: 416 Re:Exhaust Discoloration 2 Years, 11 Months ago   Recently I pulled the exhaust system off my '07 and noticed the same, including the rest of the pipe under the heat shield a gold color. My bike is totally stock but I've suspected since new it was running a bit on the lean side, but overall it runs well without excessive popping and so far, no puking. The plugs look fine at 2.5k. It could be they got a little skimpy on the plating process too. I'm not worried, I've had other yammies do the same thing without any long term problems.   Logged     The administrator has disabled public write access. #200565 bangngearz (User) Expert Boarder Posts: 412 Re:Exhaust Discoloration 2 Years, 11 Months ago   my 01 RS had same thing. Was told when aftermarket pipes are installed and you do not re-ject the carb that will happen. I used some chrome polish on mine, it basically disappeared... but appears to have come back somewhat. Ahh.. I got use to it.

I took mine off and replaced them with V & H and the stock pipes had only 600 miles and they had turned gold and blue under the heat shields already. It is a pretty normal condition. You will see it most at joints and bends where they get the hottest. If you have a place where the heat shield is turning colors at a joint I would check to make sure that joint was sealed and tightened properly.   Logged     Last Edit: 2009/06/02 10:04 By javawave.   \\\\\\\\\\\\\\\"A mind full of judgment has little room for wisdom\\\\\\\\\\\\\\\"   The administrator has disabled public write access. #200576 Cougar (User) Platinum Boarder Posts: 3210 Re:Exhaust Discoloration 2 Years, 11 Months ago   javawave wrote: The Yamaha pipes under the heat shield turn colors on all of the bikes.
