Doug,

It was on one of the LE bikes; pic of the bike in a big open structure of some kind; wanna say a barn but not sure why it woulda been in there lol ... it was on the forums here awhile back but I can't remember the thread.

Granted the chrome shields wouldn't prolly look so bad on chrome pipes, but overall the appearance was such (just imho) that the lines of the V2's that I like so much were kinda ... dunno, just looked all clumsy I guess. I mighta been a little harsh in my earlier description; sorry 'bout that ...

If I can find the pic I'll repost; not sure I'll have time though.

I picked this up on another forum site and found it extremely interesting. This kinda makes sense to me and I was wondering if any of you think this has validity.

"Quote": Gold and blue pipes result because the exhaust is running too hot. There are three reasons for this. The first, most common reason, is that the bike is running lean. A lean mixture causes exhaust temperature to rise very sharply. A slightly rich mix WILL NOT CAUSE BLUED OR YELLOWED PIPES.

However, a *VERY* rich mix can result in an extreme case of bluing. This happens when the mix is not completely burned in the combustion chamber, (either due to a too rich mix, malfunctioning coil, burned valve, improper timing, or whatnot) and rather ignites INSIDE THE EXHAUST. This can result in an exhaust pipe that GLOWS RED while the bike is running. Only in this extreme case can a too-rich mixture cause bluing.

The common myth that blue is lean and gold is rich (or the reverse) is just that. A myth.

Third, long periods of idle can cause pipes to blue because there isn't any airflow to blow off the heat. (Some people let their bikes idle WAY too long upon start up before they take off)

Some pipes can not be restored to the original chrome finish. Others can come back close with using Blue Away.

If the pipe(s) doesn't come back to looking like you want, chances are there is an exhaust cover (chrome plated) you could put on the pipes so the blue doesn't show. "End Quote"

Well, I have it on good authority we'll be seeing sometime in the near future a Fury show bike done up with Chrome Viper-2's *with* chrome V2 heatshields, so maybe we'll see they aren't as bad as I remembered; can't find that old pic I saw; was from waaay back beginning of summer. Be nice to know we had a heat shield option that didn't way-suck if we can't beat the blues, so to speak :-)

On my next Fury I will still order the Fuggin Vipers...They are fantastic! But I will go with Doug on the FC as well and I kick myself a hundred times because I didn't just to save a few bucks. He warned me and I turned a deaf ear.

Those of you thinking of the Vipers (highly recommended) Go with the Fuggin Fuel Controller as well!

Doug is going out of his way to help me on this problem and that is one fine dealer IMO.

Agree; always liked the help I got from them, and the work they do, even though I was slammin' their shields today ... ooops lol ...

Does anyone know the settings for the fuggin controller. It is easy to setup and configure but having the proper setting from the start would be great. It was not set correctly from the beginning. I would like the base setting for myself as a starting point and work from there. At first it was back fireing but now as i let off the gas it sounds like there is excess gas in the exhaust and it catches fire and makes a poof sound. i want to start with the Fuggin setting for the viper 2s and the fury with their fuel controller.

ok, i read all the posts through today's. here's what little I know:
there are several things that can cause bluing, not the least of which is a too lean mixture. also, idling for too long (aka high heat). and, yet, another tiny little thing: cleaning your pipes immediately after installation and before firing up the engine.

Just like you shouldn't put your bare fingers on a light bulb to install it, neither should you be subjecting your pipes to your bare hands. clean the pipes real good prior to their first startup.

I also got a similar response from my dealer and Cobra: if the bike runs as good as it did prior to the upgrades, then chances are you're fine. My Vance & Hines have heat shields.
Behind the shields the bluing occurs from the exhaust flanges down about 8 inches and stops. It's not a severe bluing--but it makes sense; that's the hottest part of the exhaust. It is going to turn blue.

I've been running them for about a month with none of these issues: backfiring, power fades, hesitation...nothing. I run the stock air cleaner and no controller on regular gas.

Has the Fuggin' rep stated flatly that his pipes will not blue anywhere on the pipes if you use his Controller?
That would be a very bold statement and frankly, if he stands by that I'd buy his products, too!

Skappiris,
No, I don't think that ANY single wall pipe will garantee against bluing. I did (as I always do with new pipes) throughly clean with jewelers compound before and directly after install. That is a good point. Blue Job also recommends their product to pre-clean pipes as well.

In my case, the bluing occured within minutes of startup with the cobra FC set at factory 1-2-0. Not sure why that happened but I was continuing to get further bluing as I bumped up the controller.

Cobra states to only bump up one click at a time on a fully warmed engine. By the time the engine was warm, the pipes were bluing.

Now that I have the controller set just short of the 'roof', I am not seeing more bluing than I already have. I plan on using 'Blue Job' to take the bluing off and then run the controller from the high settings presently down to a resonable setting without more bluing. But, I am waiting on my spike as that will change the settings also.

[skappiris]

Yo Painter: good thinking. once that new spike is installed you can work your way down. Since the experts claim it's the lean fuel mix that causes it. I wonder what happens to the pipes if the mixture is not too lean?

Cobra confirmed that their new PowerFlo for Fury will be released sometime next month. With that, they also stated that they would publish new Dyno results for it.

Vance & Hines have yet to respond to my question re: their FuelPak controller for Fury/VTX1300. Their site states that it should only be used for performance/racing and not general use.

Sure would be nice if all these guys had a more responsive tech department. Heck, if they're so busy why not push the responses to their marketing dept's or reps?
