Could the infamous 3000 rpm hiccup be geographically driven?
Why no issue at greater throttle openings?
There isn't an hygrometer sensor part of the circuit, correct?
Say you are living somewhere with high temperatures, and high humidity; therefore your mixture has more water vapor for the given volume, less room for oxygen. So you would need more fuel to obtain the same combustion efficiency.
If the ECU mapping does not allow for more fuel to compensate for the poorer oxygen mixture, then you get the cough?
This would explain why I don't seem to see the problem when the air is cooler, even if the humidity is the same.
Water vapor, or the dew point is inferior, so less water vapor means more oxygen, better combustion?
Do people living in cold places have that 3000 rpm hiccup?

I would tend agree Docc that its just a matter of my girl needing a little attention (she’s a selfish girl sometimes….), and perhaps its less about a single flaw and more about getting things all lined up properly. And you got me on the CO ‘drift”…. You’re right, that’s not a wear-and-tear thing… touché, i just got too loose with my postulating. Get a few drinks it me and it’ll get even looser… we’ll be talking MG fetzer valves and framostats in no time.
And P6x, are you implying i should replace the glow plugs on my Guzzi?
I like the tractor analogy! In all seriousness, i certainly agree that some temp/humidity combo effects how she runs, where some days they will run perfectly with no burbles or flat spots while other (usually hotter) days little hiccups are apparent, but starting has always been about the same on the guzzi’s, as they’re almost freakishly reliable in how they start, all 3 of them, in all weather, whether they’ve been run the day before or sitting all winter. In that way, they are like my diesel machines (though maybe your IH and Deere are gas? ).
Well, I also need to slightly alter my starting procedure.
The best result is achieved when you crack open the throttle AFTER you start cranking. Warm engine procedure; start with closed throttle, and open a tad while cranking.
As for the "tractor" association, it goes back to 1976. I was in the army, and the extreme drought affected animal feed. My regiment was seconded to farmers to harvest hay that could be sent to those that did not have any pasture for their cows.
We got distributed to farms, and helped loading hay on trailers tractor pulled. This is when I discovered that being a farmer had two major advantages:
-they seem to always have wine available throughout the day.
-farmer girls know their way around hay in more ways than one would initially think....
Both above perks helped with the amount of blisters I got from using a pitching fork....

Hhmm, tres delicieux! Mais, ca doit etre mieux le village d'Asterix sur les boites de sardines, n'est-ce pas?
I doubt they could put Asterix on anything without paying a lot of money to the copyright owners. Besides, I like that an obscure little artisan that produces sardines in tin foil boxes made the effort to put a Guzzi in the picture.

Quoteil a illustré une des 3 boîtes d’une motode l’époque, clin d’oeil à une grande marque Italienne qui est aussi centenaire cette année !
If you read the narrative, they are celebrating the one hundred years of operation of the brand, and as in the quote above, they wanted to "wink" at a prestigious Italian brand going through their centennial this year.

What footgoose sez. A buffing wheel, rouge, a little elbow grease, and they'll look like a pewter dollar in no time. Wipe them down one last time after installation, and they'll eventually turn golden. Fingerprints, oil, etc. will have to be looked after, or they'll get splotchy. (technical term)
I understand splotchy. Are you in the medical industry?
I used to be a diver, and splotchy is a term that we used when someone has botched his decompression stages. This is reflected in a "splotchy" skin.

also consider a clean and polish, like this one. I did mine very close to this and by hand, flitz metal polish, 3m pad, and then cloth. Took a few hours and it will return to tarnish after awhile, but once done it's easier to keep up with. If you use a buffing wheel it's even better
That looks really nice.
I was looking at something unusual, that is why I was looking at colors. But there is that fine line between bringing up nice features and looking like an old lady that puts too much make up.

I like the first one best because.
It's honest and says I'm a SS header/exhaust and don't see the need to hide it.
It has "patina"
It's not a hot-rod it's a motorcycle
It costs nothing
Being an air cooled engine the the last thing I want to do is insulate the header pipes for aesthetic reasons.
It's doesn't look like the exhaust on one of those hideous bobberised calamities that, Manscaped, mun wearing, rolled up long pant, Latte sipping, inked up barrister's would ride.
Ciao
I also favor authenticity. I would never purchase one of those "reliced/aged" guitar, sold new to mimic a vintage instrument. I enjoy something that reflects its history in its aspect.
All the rest is a matter of personal taste. I was looking at enhancing the harmony between the engine and these header pipes. Something like either contrast or upbringing.
Not disfiguring.

There is something we have possibly discounted as a major factor.
Here in Texas, you start your day with temperatures close to 80 degF. And substantial humidity. Only now have the temperatures slightly been cooler (in the morning).
The International Harvester sleeps in the garage, which is always quite warm. How much those parameters affect the mixture density and combustion? so maybe comparing Nashville and H'town does not really tell much.

Well it was between that and the grey silver one which also looks nice. I don't really want black wheel rims. But you know if you change your mind on the colour a brand new painted tank from one of the Indian suppliers that have the best service I've encountered in 18 years on ebay is like 380USD delivered to your door.
Yes if you've ever had a hankering to own an old Triumph Bonneville than this bike fits the bill, except smoother, oil tight, reliable and better handling.
Ciao
You would never have wanted your Bonneville or Commando "oil tight"! it was part of the brand' signature; since you like authenticity.

Believe it or not, the maximum speed limit in the whole country is 80 km/h. In Port Vila, the limit is 50 km/h and in some of the villages, even less. However, there are no radars, speed cameras, speed traps or even pursuit vehicles - but any big bike is easily recognised. The ring road is about 160 km so if there are no stops, a bit over two and a half hours if you stick to the limits.
A TT? Perhaps with Stelvios or equivalent - but you'd need a lot of people to ensure the pigs and dogs stayed off the road.
I guess 80 km/h is reasonable, especially with stray animals.
When I lived in Sicily, I was the only Harley Davidson owner in Vittoria (RG) 1989. It did not take long to single me out. First, not Sicilian, and then an HD in the land of Vespa and Ape....
I am sure people would be thrilled to see Stelvios and Le Mans....

I also wanted to report that since the temperatures have considerably cooled down here, in Houston, the V11 does not cough as much as before.
I have not done any substantial mileage lately, so it needs confirmation. But I use the bike to run errands, and I have not had any sign so far.

When I was in battle tanks, all the cabling was shielded and tested in a Faraday cage. I am talking about the systems to automatically acquire targets and follow while the tank is moving. To isolate from electrical motors interference.
There should be something commercially available for the spark plug cable? no?

If I'd had MPH that close they would have done my clutch for sure
Unfortunately, these guys are one of a kind.... and judging on the amount of vintage motorbikes they have at any one time in the shop, I hope they keep going.
I am concerned they do not have any apprentice working with there, to learn the craft "on the job". All the workers are senior citizens...
And their usual turnaround is six weeks.... I have so far got a better treatment, they really like their motorcycles... I have seen more than a few beauties there... mainly BMWs.

Of those three, I would choose the black, but try to get it satin to better match the engine. Personally, I grown to appreciate the "bronze" [atina of the V11 header pipes. I suppose they have something similar?
They have some Bronze colors. They could also chrome the exhaust so it would look like the StayInTune terminals. Unfortunately, my sampling tool just takes one single point so I don't get the texture of the tint. I could give it some texture so it would look better. The black is actually the Satin Black. But sampled on 1 pixel.

What do you think? I used the colors from their palette, but did not really try with the "rendering" because it takes a lot of work to get it right.

If you mean "Guzzi specific tooling" there is only 1 and that's the flywheel holding tool which is cheap to buy and needed when torqueing up the flywheel bolts. Maybe a clutch plate alignment tool for the twin platers. Not necessary on a RAM single plate unit. The rest is just std tooling. Even buying a few special tools is a lot cheaper and easier than taking it to a Mechanic.
Ciao
I indicated "safely" for a reason.
It means having the proper work environment. It means some kind of setup to work on your motorcycle. I was not specifically hinting at Guzzi special tools.
Starting with the basics means (at least to me) the motorcycle lift, with appropriate stand and whatever else necessary to work in good conditions.
It also means torque wrench and various set of tools which may or may not be necessary depending on what you want to do. At least for me, this is the way I work on equipment.
When you say cheaper and easier, I will agree with cheaper, providing you already have a setup. I don't have anything at the moment, and just purchasing the few items required to rill two holes to install the formation instruments is proving to be an ordeal. Some of the items I wanted are back ordered, and I am yet to receive them.
But most of anything, my issue is space. Taking apart requires also a bench, maybe a bench vise and so on.
So easier? I would say MPH Houston has proven to be fairly cheap for what they did on the Le Mans so far, and I live 15 minutes from them. If I had not wanted to install the Formation myself, I am certain they would have drilled the two holes and tapped them for free.
And MPH is not the only shop that could cater to my Guzzi here.

Wow....
You must be the only Moto Guzzi Le Mans owner in that part of the world!
How long does it take you to go around the island? as far as I can see, not many roads to stretch your twin cylinders...
You should maybe organize a TT?

So I am looking at least $1500 if I have a shop do it
To pick where @footgoose has left off, it is not so much about not being a "trained mechanic"; rather the required tooling to carry out the job safely is what makes it inaccessible to any other enthusiast.
I consider myself as a green horn with my V11, but I have already learned that getting the basic setup to work on your Guzzi is not as easy as I thought it would be. It is a relative investment, unless you are going to commit to do everything yourself.
Now speaking of workshops willing to carry out the job; I am fortunate to have several outfits willing to work on a Guzzi V11 2004 in my neck of the woods. I suppose you know, but a lot of motorcycle dealerships don't work on older bikes, including Guzzi official dealers.
I do not know where you are located in the USA, but you may want to check with whoever you think could do it, and make sure they would.

That would be so awesome, if true.
The only radial engine tie I see as a non-mechanical engineer is the cylinders are in line with the chassis, and out in the airstream.
Would add some more significance to the golden eagle mascot, aside from the obvious nod to proto-Italian/Roman glory.

I was thinking that perhaps the Guzzi singles were inspired by WW1 aircraft engines (Anzani,etc.),and the trend evolved into more cylinders... Just a thought.
I was going to post the exact same thing.
I got that story from an Italian enthusiast while working for Agip in Nigeria. He told me the V twin Guzzi was inspired by aircraft engines. I wish I had asked him how he knew that.

3000rpm hiccup

I lived in Argentina from 2003 until 2008....
Tango is not something easy to master; besides you can only Tango properly with someone who knows how to dance it well not withstanding that person and you need to have danced it together...
On the other hand, you can Waltz with just anybody as long as you understand 3/4.
