At the 1700 mile mark I replaced my exhaust with the more expensive British classic 60's system. Up to this point, the stock system did well, and had a slight gold tint to the header, hardly noticeable.
Since then, I have put on a few hundred miles on the new system. Man, it's loud, even with the baffle in. The pipe has been blueing up, but if I let it cool and scrub with Blue Away, it gets pretty clean.
I did not rejet, as the plug looked great, nice tan, and I kept the stock filter.
I took the plug to a local Triumph mechanic, and he thought the plug was perfect. He did think the Blue Away was taking the chrome off gradually (it is a paste).

Why are the stock pipes more durable?

Do you worry about the blue (it's a pia to have to constantly clean it).

Could it be lean? The plug doesn't think so. I do get a rumble decelerating though.

Anyone use a good product to remove the blue?


I want to ride, not spend all weekend cleaning the bike (but I have to keep it as clean as Perla, I have a standard to maintain you know). ::)

Different chroming processes are weaker to heat, maybe that one will blue up even at the same temperature.  The thing about it is that it should be running cooler with more airflow, even if the engine is running a little bit leaner (correct me if I'm wrong on this, but doesn't the stuffiness of the stock exhaust hold more heat in? or is that offset by richer combustion?).  It may just end up blue no matter what you do.

Mine has blue on it too.
If the blue happens pretty quickly, you might check your ignition  timing to see if it is more retarded than specification calls for.
Retarded timing will blue a pipe pretty quick.
Also, a lean mixture can do it too, but usually a little bit slower than the retarded ignition timing.
If you have  rumble/popping on deceleration, try turning your air bleed screw in 1/8 to 1/4 turn, and see if that helps.

Bernie, there is only one Perla.   I've heard rumors that he changes headers after every ride and buries them so ono one will know.  He'll never be able to sell that property...

My header turned BLACK in no time.  Plug is a tan or light brown. ( Tracy also put in a different jet before I picked it up, though)  Anyway, my bike runs fine.  Your bike runs fine?  Get used to it.  Bullet owners will understand, and the rest will assume you're a hard ridin' son of a gun.   (Otherwise- pipe tape.  Yick)

     As has been stated, you need to check the timing. Get it spot on, not merely close. Then re-jet the carb.
     Plug color is caused by several factors. Gas formulation is one of them. You are probably getting a false reading. About two months ago we started noticing better color on every plug from every bike that came into the shop. The only common factor is gasoline. The days of being able to tune an engine based solely on plug color are long gone.
     Blue away, or any similar product, will take the chrome away. Use sparingly, if at all.
     Another factor in pipe coloration is gauge of the metal. Performance pipes have thinner walled tubing. The thicker walls of the stock pipe transfer heat more slowly and evenly, and thus tend to blue less.

I had a similar experience with the factory original exhaust on my 1994 Bullet when it was new. I ordered a performance exhaust from Classic Motorworks and before installation I coated the inside of the header pipe with a product from Cycle Shack called "Chrome Guard". It works great, no change in color in over 10 years since installation!

     There are a couple of products like that. You can also fog the the inside of the head pipe with aluminum or silver paint. This also works well. Unfortunately all these treatments need to be done before using the pipe. Once exhaust runs through it nothing seems to stick.

I think he has electronic ignition. ( ? )   You can't do anything with timing in that case, can you?

I have the points/coil ignition. Using premium gas.

300 miles on the new pipe. Too late to do the inside treatment?

I'll try to pull up info on timing. My Snidal CD went poof on my computer.

I replaced my stock which was really blue with the CMW classic exhaust, no bluing just a slight tan color, which adds character.  I also put on a new larger throat carb, better airfilter and rejetted.  Runs a lot cooler.

Blue Ridge, in light of the myriad of maladies that can be had with bullets, i would not even give it a second thought.  My 05 has had a blue pipe for years now,and I dig it. As long as you are happy with the performance, so be it. I think the only bullets with clean pipes are the non running ones. ;)

Well, Br. Ernie, that is very, very good material... you're a talented comedic writer!!!   :D

The true color of Perla's header pipe is: BLUE.  Do I try to polish the BLUE off?  Absolutely not.  Why: BLUE is in, boys... it matches her other BLUE accents... and, a BLUE header pipe gives Perla character and coolness!!!  ( ;) & 8) )
Long live the Bullets and those who ride them!
