This is my second set of Rosso III (180/55-17). I have always used “sport touring (?)” type of tires on my V11. All around driving, mainly curvy roads, sometimes a careful beginners track day. “Good handling, sporty behavior.” Was rated the best in many tests in Europe back in 2017, now cheaper because of the age. Rosso IV is replacing these, I understand (already discontinued?). I have used also Metzeler Sportec M7 RR, Bridgestone S20 and Continental Sport Attack 2. And to be honest... "italian tires for italian bike...".

This was educational - I had never thought, that seen from there (US) it is of course just the same as when we talk about Harleys here…Aargh… why do they have to use those funny measurements and make my life more difficult…

I understand that the “Kit Racing Titanio” -labelled ecu which came with the “Titanium” kit was always the 15M with special mapping. For example the rpm limiter was at 8600 when the standard value is 8398 rpm (got this from Meinolf, have not checked myself). Here in my neighbourhood is a (rare) Nero Corsa with the original Guzzi Titanium Kit (Dynoed 86,2 hp/7926 rpm Crank). The software of this “Titanium Ecu” could not be uploaded to a 15RC ecu with the Guzzidiag Writer tool. The Nero Corsa came as new with 15RC and cats. The Titanium kit obviously contained “straight” absobtion type mufflers (made by Mistral I believe) without cats and the 15M ecu with ”race” mapping to go with the new parts on the exhaust.

Mee too. I have learned to trust this person, he is also on other German forums. Rides himself with a modified Centauro, a 4V and Spine Frame -specialist. I understand that he did work a long time within the official Guzzi organisation servicing Guzzis. He “broke in” all the new test bikes by riding them, so he was also “hands on” that way. It is very interesting to read his comments on spine frame Guzzis, he knows lots of details regarding different models and their technical solutions, including of course the V11 models. Had access to Piaggio data sources. A “scary moment” was to see the Scura number he mentioned. It has been mine the last 10 years (bought it from Germany). I have the complete owner history and he could tell what happened to this bike before it was sold as a new Scura originally (manufacturing date in Mandello, showroom time at the importer, etc.). Regarding the manufactured numbers; I tend to believe the numbers used here. Rosso Mandello, OK, 300+300 made, the first set numbered. Scura, 700 made, well registered here in “Scura registry”.

I have not met the owner, but I know that he is technically skilled and has had his California also supercharged earlier. But I have seen this Centauro at the previous owner & builder. "Power-wheelies were always at hand", I remember him quoting. He has also a blog, but in Finnish (google translate helps...). http://www.motomatti.fi/search?q=centauro Here are some lines of that blog: " Max constant boost pressure approx. 0.25 bar, momentary 1.7 bar.

I have been also following the German "mother forum" for GuzziDiag always. Some notes from there: " - you cannot upload the mapping of 15M to 15RC - copying the tables of the 15M into the 15RC is possible, the partially different addresses of the tables and scalars have to be taken into account (I understand that this means, that the copying of a single table from a bin file to another bin file is technically possible inside TunerPro, but the tables are not interchangeable with each other 1:1) - the contexts are much more complex and multi-layered on the 15RC than on the "simple" 15M, the key to understanding lies in the program code " So 15M/15RC mapping not interchangeable. If I remember right, the writer tool does not allow to write "a wrong map" into the ecu ? For example GuzziDiag does not connect, if a wrong ecu (like 15RC instead of 15M) is chosen.

I have always had the conception that the original ”chamber type” mufflers were made by Lafranconi. And the original Titanium -kit ”absorption type” mufflers by Mistral? But according Guzzi specs so that the ones Mistral is selling themselves, are not identical regarding the attachment to the tail pipe. I have the carbon oval version – it would be interesting to know how the Mistral oval titaniums differ from the Guzzi original (oval) titanium mufflers? I feel thalt the removable Db -killer is also a plus point on Mistrals, which can be finetuned according the liking of the user. For example I personally feel that the Db -killers off, the sound is a bit too loud, with the approved (CE) Db -killers on, too sniffy.

Meinolfs last comment on the air intake on the German forum / March 2018: http://www.guzzi-forum.de/Forum/index.php?topic=42323.0 " . . . Such changes become visible only, if the performance is measured on a test bench before/after or the effects on the lambda value are measured while riding. I had practiced that a few years ago on a V11. There was the "doctrine" that removing the intake snorkels of the air box provides significantly better air flow. A test based on lambda values showed the opposite. Without snorkels, lambda dropped in many throttle opening values. This means, that the air flow rate decreased and the mixture became more rich with the same amount of injection. My last modification to the snorkels was then the reshaping of the ends of the suction pipes to a bell shape, by means of hot air blower and beer bottle. And whether it was the shape or the beer, the air flow is now great . " I did not quite get it, if he means the "plastic pipes" themselves or the "rubber angles" in the end of the plastic pipes (what he made bell shaped). Mine is still 100% original. I had thought that if the "rubber angles" in the end would have a wider opening, maybe there could be a very slight "ram-air" effect. I don't mean that the possible ram-air effect would mean much with these pipe diameters (if I remember right, on the Sport 1100 i, with the ram-air intake pipes, the real benefit was not a lot).

Hi "BMEPdoc", (the Apriliaforum expert). (V11 Scura + Aprilia RSV C.E.R. on our backyard) Meinolf has spent "hundreds of hours" optimizing his V11 (with 15M ecu) and in reverse engineering the 15M "inner soul" on his "15M test board". Interestingly, as with the RSV CER, the stock airbox seems to be a good choice. https://www.v11lemans.com/forums/index.php?showtopic=19216&page=2 (Post #17)

The "Lucky Phil Extension Mod, made by Chuck" -owners club here in Finland would be eager to get such a retro-fit-kit :-)

I still have the Ducati Energia regulator, the 30A amp fuse doesn't like the huge amperage of it too much - the voltage seems to be OK, allthough I have a LiFePo -battery. " If using a thyristor type voltage regulator and it fails, upgrading to a mosfet based voltage regulator will offer longer lifespan and better charging system performance. Heat buildup in the voltage regulator kills the SCRs, whereas mosfets are more efficient and reliable. In general the mosfet design is better suited for the voltage regulator application demands.

I did this trip actually few years ago...there are so many possibilities on the way... The greatest passes I rode were Stelvio and Gavia. @Scud: I sent your eMail address privately to Martin (V11 LeMans Tenni), who lives in Nürnberg.

I was "insolent" enough to link this to the bro's at the German V11 Forum. I surf around that Forum too, the guys there are as nice and friendly as the Guzzistas always are.
