Thought I should ask the experts. The dealer who I bought the Cafe 7 from said all of the V7 exhausts blue and just live with it. I brought a product which I was told would remove most, not all but most. It was a very expensive powder called something Blue, It did nothing total rip-off $21 later blue, blue ,blue. Lots of pics I see on this forum have header pipes looking shiny chrome and not blue, are these just new owners who are so proud of their new Guzzi? I know I was. I have heard of coatings that can withstand big temps, do these work? I am I being totally anal? Over to the experts..........

Hot-Jet ceramic coating works as does headed wrap.
-
Sounds like you got the blues ::)
I've seen lots of small blocks (Nevadas, V7s, Brevas) with blue pipes. I think it looks good - looks like you ride that thing!
-
Pipes blue. It's what they do when heated. The reasons Harleys and such don't is that they have chrome covers on them. Blued pipes look old school and authentic (IMO)
I find the pipes on my Racer (with Arrow mufflers) have lightly blued, while the ones on my wife's Classic with standard mufflers have blued a lot. I think a free flowing pair of mufflers will help your exhaust to run cooler and blue less.
-
Unless having coaxial pipes with a lot of space between the internal and the external tube, chromed pipes will become blue, and inox pipes will become bronze.
Live with it. ;)
-
They sell a pipe coating on Ebay that you coat the inside of the pipe with (before it blues). I am sure it helps, but eventually it will probably blue.
A lot of heat with the small blocks.
-
Another way of not having colour changes is to have black chromed pipes, as the 80's Larios and Le Mans.

However, black chrome is somewhat less durable than normal one.
-
The pipes are a common feature of modern lean (hot) exhasts.
The Triumph Bonnevilles are even worse - the pipes can blue all the way down to where they run under the engine, because they have air injection to cause a secondary burn above the exhaust valves to clean up the exhaust emissions. First job when you buy a Bonnie is to block off the stupid (although kind to dolphins) air injection.

Cool Blue after 21000 miles of smiles ;-T ;-T :bike :bike

How blue your pipes get is pretty much heat related. I had a Virago that had very large diameter pipes with large radius curves. Its pipes remained blue free!
The smaller the diameter of the pipe and the tighter the radius of the curve, the bluer they get. The pipes on my Cafe look much like yours, the bigger pipes on my Stelvio are not blue at all!
One time, I tried getting the blue off a stainless steel kettle I let overheat, but I found no products worked despite the claims on the various product jars and bottles!
-
I don't really mind the blue on my Cafe, but it's asymmetrical. One pipe is blue at the top where it meets the engine and gold on the vertical portion underneath. The other is gold at the top with a noticeably larger patch of blue below. When another forum member reported something similar in an old thread, someone suggested checking plug gap and throttle balance. Did that. Still following the same pattern at 7500k. I can live with it, but I'm curious why only some bikes do this. Luck of the draw?
-
Stelvio pipes are inox, they don't blue, but bronze.

The way the FI is set when new is critical to not having blue pipes(before bike is started). The air bypass screw should be at 1/2 turn out or right close to it, no more. If you get to 3/4 turns they will blue w/you sync the bodies at a higher rpm. The only problem is idle speed, will be about 1050rpm, a tad slow for a smallblock.
-
Muddy say da blues is cooool man!
It is not a Harley, why would you even care if the head pipes get a little "tone" to them?

True but irrelevent! Stelvio pipes would become more bronzed/brown if they had the diameter of the Cafe pipes. Discolouration is all a function of how hot a particular location on the pipe gets!
-
The Stelvio engine is more powerful than that of the V7 cause it process an higher amount of gasses, and they requires bigger pipes. With the diameter of the V7 pipes it would barely function.
It would be interesting to measure the temperature of the pipes on the curve in front of the cylinder of the two Bikes after a similar ride.
However, it must be said that, in the everyday use, we use a larger fraction of the maximum power of V7 than that of Stelvio, so the bigger diameter of the pipes of the Stelvio is probably less used, and then less hot.
-
Mine are pretty blue... I just live with it. Gives it a more authentic look I suppose ;)

If you want bigger bore stainless heavy duty pipes, I have used these pipes on a Monza.

OMG, your bike looks awful with those blued pipes! Quick, sell it to me. I'll give you $500 for it. :D
Translation: Yes, you are being totally anal.
-
There are internal coatings you can use but they usually require "virgin" pipes; you would have to buy another set of headers and have them coated.
Ceramic coating is becoming popular especially around here in Charlotte NC (home of NASCAR) and now there are many options/colors/textures available beyond Jet Hot. Porterhouse on Guzzitech did a great job matching the carc and frame finishes on a G11:

I've heard of a chrome like coating called Armor Coat or something too. Lots of guys coming out of the woodwork doing coatings and the price, compared to buying an aftermarket exhaust, is pretty good.
-
I've used this - it seamed to prevent bluing, but pipes have a golden color, which really isn't too bad. Best results on new pipes.

My Griso started out nice and shiney chrome. On the ride home (110miles) they got a bronz patina even though they are double walled. Goes with the brown seat; it's no longer on the showroom floor and like grey hair; proves the bike is being used. About the only other choice is to put it in a glass display case and just look at it.
Riding in the rain will be worse!

Thanks for the advise. I will just live with it until I can't stand it any more.

Are your pipes rusting already Ross? Or some other parts? You're a fair way from the beach!

Hi,
There have been other threads on this board that briefly discussed products for removing bluing discolouration on chrome header pipes. There's not been an indepth discussion of any one product so I thought I'd share my recent experience with Blue-job Chrome Polish.
I'l begin by shamelessly recommending a URL to visit where a wonderful write up can be found about the Blue-job product. There is no point in me repeating the information when Webbikeworld has done a magnificent job of describing the product.
Blue-Job Chrome Polish Review by Web Bike World (http://www.webbikeworld.com/r3/blue-job/blue-job-chrome-polish.htm)
Although Web Bike World did not get the result from using this product as they expected, I found the product did an outstanding job of restoring my damaged pipes and mufflers back to their pre-damaged condition with moderate effort and in a short time.
The background starts when I recently brought my V7 in for to the local Moto Guzzi dealership for a valve adjustment. The headers on the bike were slightly blue at the exhaust ports when I dropped the bike off at a repair depot, as depicted in this photo:
(https://lh6.googleusercontent.com/-rpwXzDbC_bs/T8_9J9JXyHI/AAAAAAAABsY/ImrlPNk3MwI/s400/IMG_0597_cropped.jpg)
I received the bike back from the repair shop with both pipes blued right to the muffler, as shown in these photos:
(https://lh4.googleusercontent.com/-CjGf7NgIOOo/T8_9KQWjffI/AAAAAAAABsY/33ZheoKWVmw/s400/IMG_0880.jpg)

(https://lh4.googleusercontent.com/-iLSh880LIMY/T8_9K-7t83I/AAAAAAAABsY/yS5SALAVAB0/s800/IMG_0884.jpg)
The repair shop denied all culpability so I was left to repair the problem on my own. I thought I'd give Blue-job a try. I purchased a tin and read up on how to use the stuff. The recommended practice now is to use a Random Orbital Sander (ROS) to speed up the process. I highly recommend this method myself after trying it. Instead of purchasing the Blue-Job Exhaust Wipes (a seperate product), I went to a local drug store and bought a package of 200 unsterilized non-woven surgical wipes for about $3.00. These are wipes used for cleansing wounds. They are 4" X 4" squares which fit perfectly on the ROS. The loop and hook on the ROS secures the wipe. I sprayed a little water on the wipe and sprinkled a tiny bit of Blue-job powder on the moistened wipe. I'll emphasize that it does not take much powder. After all, the can of Blue-job only contains 14g of powder. I did the entire exhaust system including both pipes and mufflers with just under one can. The moisture on the wipe will create a paste of the powder. This paste along with the vibration action of the ROS quickly removed all the bluing and golden tarnish, leaving behind the original chrome finish. Certain spots were difficult to get to so I resorted to hand polishing those areas. The task involved cleaning all pipes and mufflers and took me 2 hours to complete. The chrome was fully restored to its original sheen, leaving only a few areas with a only hint of blemish.
I highly recommend this product. When used properly, it removes bluing, golden tarnishing and residue from chromed components. The package emphasizes that this product will not work on plastic chrome, aluminum and other surfaces.
-
Good to hear of the positive results, as I bought a little jar of the stuff a couple weeks ago and am looking to use it on the bikes soon. ;-T

Hi all,
I just purchased a new 2013 Moto Guzzi V7 Stone, so far, about 50 miles on it and the headers are turning blue. Is this normal? Or should I bring it back to the dealer (reason?).
Thanks.
-
Buy it at MPH ? give them a call I am sure they will tell you it is normal are both headers bluing equally ?
-
Lean fueling to pass emissions regs
-
It's normal on any single-wall headers.
-
It's normal on any single-wall headers.
Triumph's new family of Bonnevilles does the same .... pipes are single-wall. On the older carb'd Bonnies (2001-2008), first step, prior to delivery (if possible) was to rejet slightly richer, and pull the air induction system that allowed air to be pulled into the exhaust pipes near where they joined the cylinder head.
I'm thinking both my big blocks have double wall pipes. First, because the Griso at 4200 miles has lovely gold exhaust pipes (1200 Sport still looking alright, at 34k), and secondly, because of the huge outside diameter of the exhaust pipes that could only be accounted for by double wall pipes .... I'm guessing here.
-

Yes sir, MPH Cycles. I'm the first owner of one in Houston. Yes, both headers are bluing, more on the right, but nearly the same. I have to go see them on the weekend anyways as I am getting the Mistral pipes fitted (as per this boards recommendation).
Speaking of which, no "rejet" is requried with the Mistrals right?
-
Griso is double walled. Still, on the left hand pipe I have a wee bit of bluing at the elbo.
-
They all do, and the header pipes are double-walled.
It also seems like some are willing to PAY for factory-bluished pipes. **C

-
Yea, bluing is normal. Keep in mind that in the days of cafe racers blue pipes were a mark of pride. It meant that you were a hot rider, and not a sedate plonker.
But in those days of carburetors the fueling was a little richer, and the exhaust a little cooler. Blue was a little harder to do.
While mine is well blued, I recall seeing two V7's with light brown pipes. But both of those bikes were owned by older fellows.
-
What bikes DON'T blue their pipes today (I don't think it's a large number) - I would guess it would only be some models with dual-walled headers and/or some model with painted/coated headers?
I would assume the vast majority blue, but I guess I haven't been paying close enough attention.
I know that pretty much all Harleys, lots of BMWs, and both the Guzzis I've owned all did.
-
We get it. You're not a plonker. ::)
-
We could use a poke graemlin so folks know when we are teasing them. :)
-
Thanks for all the advice! :)
Yes, I do ride the V7 in the 4-6rpm ranges so I'm not slow with the bike. :) I guess that is the cause?
-
Everyone is quick to 'blame' lean mixture.
I have had a number of occasions where the exhaust systems on bike would glow red because the mixture was too rich. never had that happen from a lean mixture.
-
I always thought lean would make gold/yellow and rich/normal would be blue. If the blue bothers you they Harley shop sell blue away paste.
-
I've had some success using this (I think, hard to tell what my pipes would look like if I hadn't ):
http://kreem.com/blueshield.html
Works best on virgin pipes.
-
I know this has been covered before but I'm wondering if anyone elses pipes have turned really blue. My Stone has much bluer pipes
at 350 miles than my old classic had at 1000 and bluejob isn't getting it. I know, I know '' just live with it , mate" but I,m just axing.
-
Yup, very blue on mine. Is what it is.
-
Its the modern exhaust temps - very very hot and you cant do much about it .....only a double walled exhaust or a chrome cosmetic cover on insulated standoffs, would stay nice and bright chrome - like.
I used up 3 tins of Blue Job powder on my 2009 and then discovered that Dursol Shine works even better (and cheaper).
However be warned that if you keep at it, with either product, - you will abrade through the top layer to the nickel plate, in places .
I still use a bit sometimes - just to even up the sides.
-
Yep, not a garage queen....blue...don t worry, be happy
-
"Blue Headers" on your bike just prove to all the poser's that you actually RIDE your bike. Yeah I know, double wall pipes would be nice, but apparently illegal outside of Nippon.
-
I know some of the new Triumphs have double wall headers.
-
I've seen a few lately with a very bright blue hue that is actually really nice looking. I don't know what causes the difference in hue but some look so nice I hope when I get a bike it matches them.
-
I didn't think I would be but I have become a fan of the blue.
-
it's because the bikes are so lean from the factory for emissions, my Griso with Guzzitech fueling hasn't ever turned blue since I bought it in 2009, my V7 racer blued in 100 miles. I have Todd's o2 Optimizer on order and PC V on order to address the crazy lean. My Griso's air to fuel ratio was 16.8:1 and after I set it to 13.4:1 and my legs/Knees are cooler also.
-
16.8? Holy crap....why so lean? That's way lean even for cat-con operation. ???
-
I Jet Hot coated my pipes on my Norgy, because as much as I ride in the winter my pipes started to splotch looked bad Ill look for the pic of the coated pipes.
-
Chrome is good, blue is better. ;)
-
Thanks for all the advice! :)
Yes, I do ride the V7 in the 4-6rpm ranges so I'm not slow with the bike. :) I guess that is the cause?
Nope.
Cause is that you USE that bike. ;)
Exhibit bikes may stay shiny and chromed. Real darlings catches the scars and scratches of life.
-
;D So does that make me a darling ? A nice young lady did call me sweet pea today . I just blushed a little .
Dusty
It sure does, honey. ;D
-
So the little V7 has 3500klms on it now and the header pipes have turned blue which doesn't bother me. But I am also seeing bluing on the Mufflers and under the heat shields which does bother me.
I can understand the header pipes but at the mufflers. Not happy at all.
Anyone else have this happen?
-
The header pipes on both the Classic & the Special blued quickly. The blueing on the Classic has now browned to something akin to rust. Polishing (by hand) reduces the blemish, but not eradicate it. Both mufflers, the Staintune on the Classic & the Mistral on the Special, brown at the front end between the seam & the header join under the footpegs (? a different type of stainless, perhaps?), but a little bit of polishing (with Staintune's polish - gifted to me by the company's owner when he caught me in the carpark behind the pub near his office) restores the finish. The clamps brown too, but the polish works on them as well. Before I had Staintune's polish I used Autosol. From memory, that worked also.
Not all that long ago (perhaps April/May) I took the stock mufflers out of storage & cleaned & polished them, before putting them away. They'd been the bike foe some 12,000 km, had road tar, dust & dirt in all the nooks & crannies, but can't remember any bluing or browning, though tjere may well have been. Anyway, now they look good, all packed away in their box, so I can no longer tell. The evidence has been disappeared.

My Guzzi pipes haven't blued because they're black but both my Ducatis have the blues. I polished the headers as they were initially a dull, almost rusty colour and they started turning blue within a few minutes of running, now they have a nice graduation from blue to gold and lots inbetween.
I like it, makes it look used, this is what the Monster's pipes look like;

For the record, this bike runs on the rich side rather than lean but it does run quite hot.
-
Wore my elbow hinges out working those pipes with Blue Job for years on 2 bikes. After these guys yelled at me I gave up and I am much happier. It's really not that bad as the bluing kind of mellowed and quit spreading down the pipes.
-
blue pipes are another example of under engineering.....if they are supposed to be blue they should come in blue.....I bought a bike with chrome pipes not one is blue and one is chrome...due to another fine example of under engineering
-

Or it's not worth worrying about.
These bikes don't lend themselves (by shape and style) to heat shields (Harley's method of hiding it) and most other brands don't bother (unless on higher end "cruiser" models) so who cares?
If you don't like it wrap or coat.
-

Your '16 Racer?
They should end up matching over time. Same thing happened on my V7 Special.

Blue pipes are good
But you can slow it down by removing them thoroughly cleaning the interior and painting the interior with high heat paint

Blue is my favorite color. I actually like blue pipes, especially when they transition from blue to gold to silver (chrome).

Blue is beautiful baby!

Rather than start another thread.....
My header pipes turned blue pretty quickly from new but I figured that was normal. I noticed today though that the header pipe is turning blue on the underside of the second bend where it points to the rear. I have plenty of empty country roads in the area so the bike gets a workout once in a while.
Normal? Any thoughts?

Mine are blue at the header and amber at the crossover and cat. I don't worry about it.

Yup, same colors on both sides.
And thanks, I like it too!
