  2. Excellent film - to hear Bruno Scola’s Bol d’Or story alone is gold! Early footage including V-twin 👌
  3. A few days ago I emailed Bruno dePrato regarding his article - seeking confirmation the liquid-cooled four valves per cylinder engine was the final iteration of Federico Martini’s previous work. However Bruno’s unequivocal answer on the 20th March is clear but unfortunately contains no further details... “No Federico Martini leftover, this is a new projectRegardsBruno dePrato”
  4. And then there is tomorrow, as well as a centenary to be honored were it not for the fact that the global health emergency today makes any program uncertain. If it were for Davide Zanolini, marketing director of Guzzi and of the other brands of the Piaggio group to which the Mandello del Lario company has belonged since 2004, in September it would be nice to celebrate on the shores of Lake Como where the company designs and builds at home every two wheels with the symbol of the eagle, in the face of globalization. Provided that the health situation allowed it in the maximum safety of the participants: “It would be wonderful to be able to open the plant to the public from 9 to 12. But it is a wish, health first and let's see what will happen ”. However, until September nothing should be known about the new Moto Guzzi which should be presented there, then exhibited at Eicma in Milan and put on sale in 2022. Birthday gift: "It's a very secret model, it will have a new engine and many others. news that Guzzi fans expect ”, Zanolini tells us. To a flurry of other questions he replies: “Yes, we are studying whether to go to lower displacements but not soon, also to meet young people. An entry level is not planned for the V85 TT enduro, rather we could think of variants of motorcycles with smaller displacements on crossovers. We work to create engine and chassis platforms on which to adapt different models. This next bike will be the basis for others. The new course of the second centenary will be seen in Mandello and at Eicma ". https://www.google.com.au/amp/s/www.repubblica.it/motori/sezioni/moto/2021/03/12/news/cent_anni_da_guzzi_storia_e_futuro_di_un_fenomeno_tutto_italiano_diventato_globale-291908675/amp/
  5. Patience fellow grasshoppers... The Federico Martini led engine design and legacy will be the vanguard for the 2021 new century! Confirmed here - read it for yourselves! https://www.cycleworld.com/story/bikes/dive-into-the-history-of-the-sideways-italian-vee/
  6. Yep. I’m patient - I also just keep in mind that that Mother Goose never seems to meet projected targets & always takes her time to push out another golden egg! 2015 was projected - six years later seems about right! 😆 Keeping in mind Colaninno’s description of “extraordinary in terms of technology, design and performance”, here’s what I expect will be timely unwrapped for the new century from the realisation of this R&D huge investment & development... (...even possibly suspect additional electric assist) Translated: No, this engine is totally new, a compact, liquid-cooled design that is said to meet future emissions requirements and is immensely more powerful than anything that's coming out of the Mandello del Lario plant. Producing possibly up to 140 horsepower, this new 1.3-liter V-Twin will reportedly have enough grunt to bring back the myth of Moto Guzzi Le Mans models. As in the old Honda CX500, Moto Guzzi's new liquid-cooled V-Twin gearbox will rotate in the opposite direction of the crankshaft to eliminate the torque reaction generated by any motorcycle engine with a longitudinal crank. Unlike the air-cooled V-Twins actuator, the new liquid-cooled Moto Guzzi V-Twin will be a dual overhead cam engine with four valves per cylinder and inlet shoes facing each other. Vee. Work is underway, but the new liquid-cooled Moto Guzzi power plant should be ready no earlier than 2015. Could we see this liquid-cooled engine in a new Moto Guzzi Le Mans sports bike? Stay tuned.

  7. “Sarà straordinaria per tecnologia, design e prestazioni”. “It will be extraordinary in terms of technology, design and performance”. Roberto Colaninno ____________________ il Giornale.it Moto Guzzi makes 100 years, new plant in Mandello by Pierluigi Bonora March 14, 2021 Tomorrow the anniversary. Colaninno: "A moment of pride for an all-Italian excellence" And so the motorcycle manufacturer founded by Carlo Guzzi and Giorgio Parodi a century ago, ...will have as a birthday present a new production plant obviously in Mandello del Lario, the historic seat of the Museum, whose area will also be completely refurbished. ...the birthday celebrated tomorrow "represents a moment of great pride for the whole Italian industry", says Roberto Colaninno, president of Piaggio Group. In the latter part of last year, the V85 TT and V7 were the absolute protagonists of the brand, contributing to the strengthening of Piaggio's sales in Europe, ...In short, it has always been a great source of pride for "Made in Italy", ..."an all-Italian excellence - as confirmed by President Colaninno - which has made the history of our country, without never grow old and that continues to move the most authentic passion of thousands of Guzzi fans all over the world. 86A9E8C2-BB5C-4F97-ACC8-89F40CCC833D.webp
  8. This topic is just too good to leave on a bit of a sour note...! I’ve been back revisiting all the great intake port info contained in this V11 engine discussion - unfortunately it got a little knocked off topic by old wounds but - it’s really worthwhile here for our V11’s taking note of Bill’s suggestions particularly from 6mins on... If Bill’s few interventions netted some 90 odd HP on a street 850 squarehead - one wonders what may be realised performance wise from similar minimalist 7-8mm floor raised D-porting on our large V11 ports? An 850cc sq/head outrunning a BMW R1100S is actually very impressive!! R1100S specs quote 0-60 MPH @ 3.86 sec & Top speed 139 MPH. Pressureangle’s own work to raise port roof & fill floor is on the money - but maybe he reworked it back to rounded or did it end up flat too? D-porting stock V11 ports hmmm 🤔

Also see: Guareschi Corse 2 (Videos) Words and pictures courtesy of Moto Guzzi. Website: www.guareschimoto.it 2018 Varano Project The name Guareschi instantly conjures up images of the merging of two quite different worlds and two very distinct passions, namely for Moto Guzzi and for bike racing. This well-known Moto Guzzi dealership in Parma was started back in 1974 by the father of the Guareschi family, Claudio, and his two sons with incredible racing pedigrees: Vittoriano, who raced in the Supersport and Superbike world championships before becoming team Manager in the MotoGP and Moto3, and Gianfranco (A.K.A. “Il Guaro”) who, amongst all his other achievements, also took the amazing Moto Guzzi MGS01 to two legendary wins in the Daytona Battle of Twins in 2006 and 2007. Two illustrious racing careers that led the boys to storm their way around various circuits half way around the world, without ever keeping them too far removed from the family business and from their shared passion for the Moto Guzzi Eagle, so much so that together they won the 2017 Italian Vintage Endurance Championship on a thundering Moto Guzzi Le Mans. This success sparked the idea to come up with a plan for a “racing Moto Guzzi”, but this time based on a more modern Griso. Not just a simple “one off”, but rather a fully-fledged racing kit that would be available to anyone who loves to take their Mandello twin out for a spin on the track. Hence the birth of the “GC Corse” (or “GC Racing”, where “GC” stands for “Guareschi Claudio”): Varano Racing Frame Kit. According to Vittoriano, “This project represents our desire to be out there on the racetrack on a racing Moto Guzzi. We have done everything we possibly could in the racing world and now that I no longer had to worry about winning a world championship and both of us finally had some peace of mind, we really felt like we wanted to be out there racing on a Guzzi. While we were preparing the Le Mans for the 2017 Endurance Championship, we realised just how well the bike was running and that we had all the necessary skills and experience to come up with a bike that is both competitive and fun to ride so, as soon as the season ended I began designing, starting from the Moto Guzzi big block.” According to “Il Guaro”, “The idea of turning it into kit form was inspired by the requests we received from our customers who race Moto Guzzis in various championships. Over the years we have modified their bikes time and time again, one part at a time and entirely in a bespoke manner. All that hard work is now available to anyone in the form of a kit that is not only affordable but also modular, so that each individual rider can fit the various components depending on the level of performance that he wants.” The “basic” Varano Racing Frame KIT includes a complete frame, a saddle-mounting frame and air box housing (which is none-other than the original Griso one), an instrument-panel mounting frame, a footrest kit, clip-on handlebars, a fuel tank, an oil breather-tank, body panels and a tailpiece and tank cover, all of which can be used in conjunction with any 2- or 4-valve Moto Guzzi big block linked to a 6-speed gearbox and Moto Guzzi’s CARC shaft–drive system. The easiest model to use as a base is obviously the Griso since you can retain many of the bike’s original components, for example the wheel rims, brakes and brake pads, the shock-absorber and the front forks, but the kit can also be adapted for use on the Breva, Norge, Sport 1200 and even the Stelvio models, with an endless range of customisation options available. “Over a period of 9 months we succeeded in putting together a kit that we’re very happy with, no easy task by any means since both Vitto and I are extremely fussy and demanding guys. The thing that we’re most proud of is that we have been able to come up with an affordable way for many guys to experience the thrill of taking a Moto Guzzi out on the track. Make no mistake, this is still a Moto Guzzi, but with the kind of performance you might expect from an upgraded MGS01, or at least from one of its direct descendants. In fact, we were keen to maintain the Moto Guzzi tradition and identity both in terms of lines and technical features, starting with a tubular-steel trellis frame that harks back to the classic Tonti frame. The best part of any Moto Guzzi is obviously the way it rides. We began conducting initial track-tests back in March. Since then, we have made quite a few changes and we now have an end-product that is a perfect blend of manoeuvrability and stability and the feel and predictability of a modern racing bike, combined with the unique features of this engine. The bike gives you an incredible feeling of safety, irrespective of whether you’re just riding for fun or pushing the bike to the absolute limit, and we can certainly vouch for the fact that we’ve tried the latter too, right Vitto?” “You bet! We took the bikes to the last two legs of the 2018 “Trofeo Guzzi” and “Gentleman Cup” races and came away with 1st and 2nd place overall at Adria in September and 1st, 2nd, and 5th places at Misano in October. For us, this project was not only a way of combining our respective experience and passions, but also the missing link in terms of fulfilling one of our dad Claudio’s dreams. The passion for Moto Guzzi is something that is very hard to explain, but in our case it’s undeniably a family trait. Many of our friends in the Guzzi community display this passion out on the road every day, while we have chosen to display it out on the track as well, but all that really matters is that this very same passion is what unites us all!” 2020 GC Corse Project Interview with GIANFRANCO “GUARO” GUARESCHI: Let us start with the bike: what is the origin of this beast? “This GC Corse is a different expression of the “Varano Kit” fairing with which we dominated the 2019 season of the Gentleman Cup, winning all the races and even putting three bikes on the podium in the Magione race. Once we proved that the bike worked on the track, we said to ourselves: why confine it between the kerbs? So, from the idea to take the substance of this bike to another area, closer to the road, the naked version was born that we presented at the Motor Bike Expo in Verona. It was still a prototype version, with half-handlebars and superstructure in aluminium, now the fairings are full carbon and to adapt it to Stefano we fitted a wide “Griso” style handlebar. The result is a modern naked, muscular but with some retro sport elements. If you think about it, the original Superbike were like this, with the wide handlebar, and the races of the origins, the ones where Moto Guzzi dominated up to 1957, were held on road circuits. In short, even if the “outfit” is different, the philosophy and heart remain those of the Varano kit. In this case, the engine is a Griso style 4-valve, prepared like you do for a real racing engine, bringing the displacement to 1310 cc (the maximum allowed by the regulations) and coupling it with a custom-made exhaust system. We’re talking about 136 HP at the wheel at 7,500 rpm and 144 Nm at 5,300 rpm, respectable numbers, even for a GC Corse.” And where did the idea to race in the Italian Hill Climb Time Trial Championship come from? “First of all, we have to say that in Moto Guzzi’s DNA uphill races already existed, as part of a somewhat recent past. Just think of the V11 Ballabio, a version celebrating the victory of the historic Guzzi test rider Cesare “Cecco” Micheli at the Ballabio-Pian dei Resinelli hill climb of 2002 with the V11 Sport. But our approach, I must admit, was almost by chance. We’ve known Stefano since he raced with my brother and me in Sport Production in the ‘90s. He comes from a family of bikers and above all he is from Parma like us. If someone from your own city wins 19 Italian titles you cannot help but follow him, but we had never thought of doing something together. It all began when we met him in person here at our dealership in the winter of 2019, through common friends. We had a friendly chat and he was almost leaving when he saw the GC Corse we were preparing for MBE; 30 seconds later, we were already asking him: “What if we make a naked bike for you to race?” From an idea to the race debut… to the next season? “The GC Corse is a nice change for him from the Triumph Street Triple he used before, and between Covid-19 and other issues this year, he managed to do very few tests and only two races in September. That 2nd place, however, made us understand that we are on the right track. We like working with people who are on our wavelength in terms of passion and ambition, but also for the ability to have fun. It’s a job but it also has to be fun, and Stefano took on the project with exactly this spirit. But we are still racers, so for 2021 we’re going to start out fierce, aiming to tackle the whole Italian championship in the top category, the 1000 Superbike, and to rank first. We’re talking about four-cylinder 1000 cc supersport bikes driven by the best Italian road racing specialists. It won’t be easy, but we have the whole winter ahead of us to get ready. My brother and I continue to develop the bike, with Stefano adapting and getting into symbiosis with it. I’m sure it will be a great adventure both for us and for the Eagle fans.” Interview with STEFANO MANICI: What prompted you, after nine winning years with the same bike, to take up this challenge? “2019 was an important year for me. My 19th Italian title, the 11th consecutive, won with 19 as my race number (my idol was Freddie Spencer): in short, a milestone. I’ve been racing for almost thirty years, and I felt satisfied, and after nine years in a row of wins with the same bike, I was losing a bit of motivation. I had thought about doing a few more races but nothing more unless the right kind of stimulus came along. And then it came with that question the Guareschis asked me at the end of 2019. Consider that no one has ever provided me with the bike; I simply couldn’t ignore this expression of esteem and trust. In addition, I had never raced with a twin-cylinder, much less with a Moto Guzzi, which meant lots of unknowns but a lot of curiosity. Then there was winter, in February the lockdown with the championship postponed, so we were all busy thinking about other things and honestly, I imagined that the thing wouldn’t materialise. Then I got a phone call from the Guareschis, who confirmed that they were going ahead with the work, even though slowed down, and finally, in June, I got the call saying the bike was ready!” What was the first impact with the GC Corse like? “When I finally started it up for the first time and I felt that sideways shudder when I opened the throttle, I must admit that I thought, ‘How can I race with a bike like this?’ Then as soon as I could test it, first on a small track and then on a road closed to traffic, I realised I had a special vehicle in my hands. On the straights at first, I didn’t seem to reach great speeds. The real surprise was the first uphill hairpin bends: in the race you confront slopes up to 8% and with the low end torque this bike has it seems like being on level ground, there’s practically no difference. Of course, going from the three-cylinder 675 cc to the GC for me meant having to relearn everything. To understand the different weight distribution, to learn how to take advantage of the torque at low and middle revs instead of the acceleration, use the engine brake, which can be really important when braking uphill. And finally, I’m understanding that Guzzi bikes have their own particular character, like the Guaro says: you have to drive them like they want, if you try to force them they become beasts that aren’t much fun and don’t forgive you; instead, if you follow them, they give you magnificent satisfaction.” In fact, satisfaction arrived with the 2nd place win in September! “Maybe it could have come even earlier. The first double race weekend was postponed to August. Just think that I had already been in the car for a few hours headed toward the site, leaving at four in the morning, when I got the news that a member of my team had tested positive for Covid-19. I had no choice but to go back home and do the necessary tests. So, my first appointment became the one at the end of September with the races at Pieve Santo Stefano, on the Passo dello Spino. Saturday, I admit, was really hard. The asphalt was half dry and half wet, and with the Friday tests skipped and the bike still in the prototype phase I practically had to do adaptation experiments during the race. At the end of the first day, I brought home a 7th place at five and a half seconds from a specialist like Stefano Bonetti, on one of the fastest tracks in the panorama of Italian races, where the sport 4-cylinders are favoured. If it had happened last year, I might have skipped the Sunday race because of the disappointment, but this year I decided to put myself on the line, so I rolled up my sleeves, taking advantage of the first day, participating and winning the Trofeo Crono Climber category of regularity, to do as many km as possible on the bike. On Sunday the weather changed, and the pouring rain gave me a good feeling. I did nothing but try to be “smooth”, using the low-end torque of the twin-cylinder and limiting the gear changes on the bends that the day before had given me some traction problems. I didn’t realize I was fast in the first heat until I went down to the paddocks and they told me I was 1st, having trimmed three seconds from Bonetti. The second heat went equally smoothly, and I closed in 3rd, despite an improvement of two-tenths. In a situation of equal points, the first place of Race 2 was given to the rider with the best heat, even though considering the times I would have been 1st. Anyway, I was satisfied: a podium in the second race and a heat won. A great feeling. But unfortunately, it didn’t last long. Loading the bike in the rain at the end of the day, I injured my shoulder, serious enough to have to give up the last round of the year. So that’s how my season ended.” Let’s talk about next year. What are your expectations? What are the biggest challenges? “First of all, I’m hoping for a normal season, in which I can gradually improve my performance, both mine and the bike’s. On a technical level, the bike is already doing well. There are some aspects we can work on, like the weight, which is approaching that of the bike I rode before, or the gearbox, that could benefit from an electronic shifter. As for me, I found the stimuli that I was looking for and I think that we can have a good season in 2021, when we have fun showing that a Moto Guzzi can finish ahead of the 1000 Superbikes. Already the fact of the wide handlebars, in this category, is a particular choice: racing with a bike like the GC Corse is even more intriguing. At the paddock lots of people came to look at it and asked, ‘What the heck is this?’ They’re going to have the opportunity to find out, I have no doubt.” Stefano, what’s special about uphill races? “I love everything about motorbikes, and in the past I also raced in other disciplines too, but in some races you don’t even know who’s next to you in the paddock and the spectators are made up of family members and insiders. In uphill races we are all friends, and the audience is everything! I’ve been in races with 10,000 people watching, just like car rallies were – and a bit still are. I also find that there is something special about racing in people’s home places, instead of having people come to your home. A little boy comes by, an old man comes by, a fan comes by; everybody’s interested because they are involved, even if it’s just because you’re racing on the road that they travel in the morning to go buy milk at the dairy. There’s still that bread and the engines of the past. You can afford to go with your family, your children, your dog, and maybe, with the excuse of being there, you can also go to visit some special place in this magnificent country of Italy. For me it’s a bit like going on holiday. In fact, I have to thank my family-run team: they help me in everything and if I’ve continued to race for 30 years it’s because they’ve always been by my side. We’ve had some dark years, with newspapers not talking about the discipline, as if it didn’t exist, but in recent years a new scene has opened up. The participants are there, in part for the costs – just think that with a set of tyres you can do two weekends of racing – and in part for the passion it arouses, which was still felt even in this year of restrictions. After Pieve Santo Stefano, the news of the race came out in several sports papers and what impressed the journalists most was the fact that I raced with a Moto Guzzi, albeit heavily modified. I like to think that it’s a good sign for both the sport and the brand. For this we must thank the Guareschis, the real creators of the return of the Eagle to racing.” So, we have to conclude the interview, would you like to leave a message to the Guzzi community? “I’m tiptoeing into the world of Guzzi passion, but I’ve already had a lot of evidence of how strong and widely felt it is. I think about a friend who’s a Guzzi fan who, when he found out I was going to race with GC Corse, almost had tears in his eyes. I think about this interview, and the unexpected request flattered me and made me reflect on how many people are entrusting a piece of the sporting honour of the Eagle to me. I hope to be able to keep that honour high, and even more, I hope to meet lots of passionate Guzzisti on the tracks of my next races. You are all officially invited!”
  10. Well, under this topic What are they thinking... purloining, pilfering, pickpocketing Guzzi’s colourful history?? Oi! Get off the grass!
  11. The moody lighting isn’t really relevant for me. The price is damn high but... 115 ft. lbs. Torque would be hella lot fun! 140 HP & 10 second Quarters would be nice. If someone pulled up on one I’d be ambling over for a interested chat for sure! Good luck to him
  12. It’s been awhile... This is handy for all those who haven’t yet experienced the V85 I should add - myself included! 😝 The rider also gives some interesting observations if you feel it’s worth your 10 minutes of almost VR immersion Anyhoo... trust it’ll be useful for some
  13. The newer cylinders are different, has 0.3 mm less hight for more compression ratio (9.2 old / 9.5 new).

    '03 V11's

    Careful with what you assume - the actual OEM O2 sensor location is underneath on top of the usual stock crossover - with the front balancer added according to Guzzi to improve midrange. For some this’ll be an anathema - but I hold the view that the 15RC feedback modulation is an evolutionary improvement by Magneti Marelli. When married with the improved LSH24 offering higher cross count sensor speeds it performs phenomenally. Disabling feedback imo isn’t really a step forward - it’s just a shortcut means to an end. Kind of like chopping out tonsils & appendix’s. Sure, it can be done - but better...?
  15. Adding this here as most appropriate for subject resource... As you know our V11’s are not spoilt for choice on cams - but of the options available - choosing which one can be extrapolated. 🍻
  16. Please yourself LP - don’t lose sight of the fact that Ube’s recommended tip is in ‘actuality’ now installed on my bike - the experiment has been performed - it’s been put to the test. I confirmed for myself the benefits, as recommended are real. Nothing too ‘Theorists’ about that to my mind. Everything else is just waffle, heck, it’s a forum - but the reality of implementation results is what counts. Ube is highly respected on the AG forum - he’s a Guzzi specialist mechanic. It’s only a few buck$ O2 people - yet you’ll get back 10x the results. It’s reversible - what’s not to like? It’s unfortunate imo for those owners of O2 equipped 15RC bikes on this forum that SimoneV11’s post here on V11lemans wasn’t picked up on back in 2008... ________________________ SIMONEV11 Posted May 10, 2008 THE PROBE is LAMBDA you MUST BRING THE BOSCH LSH24 YOU HAVE THE LAW TOO SLOWLY LSH15 ________________________ Anyhoo... seems your mind’s closed on this Lucky Phil - & you don’t have the V11 models that this O2 swap would benefit anyhow... so I’ll close loop & refer you back to carefully reread Ube’s post and reiterate Ube’s comment, “the bike is more enjoyable etc”. Ciao down
  17. 👍😋 Curiosity got the better of me too after I translated Ube’s post - and importantly the procedure was easy & the price was right! I also had another bung welded in on my right exhaust when mounting my MassMoto crossover so I can swap it over from left to right as I wish. (like to have two in unison if possible!) I half expected, if nothing else - I’d have merely renewed a consumable item as they are a finite component so would be no harm done. But the more you look into it - be happy not all sensors are created equal...! The LSH24 upgrade is far better for O2 15RC V11’s. It’s low/mid (under 4000rpm) changed manners - smooth, stable & superior performance is phenomenal. Another observation I should add - the boundary between closed & open & back again is seamless. The ECU may well be the brain but the O2 sensor is its spinal cord - together the Central Nervous System! Let’s finesse a little more - & differentiate open & closed... Open loop is basically a system without feedback - it doesn’t make any adjustments if the fuel mixture is not burning well & will run rich or lean at any given time with no correction. A motorcycle operating within closed loop will sense unburned oxygen & sends a signal to the ECU that will allow the ECU to correct the mixture for the next firing. An oxygen sensor is a chemical generator - it’s constantly making a comparison between the oxygen in the exhaust manifold & the air outside - if this comparison shows little or no oxygen in the exhaust a voltage is generated. With the ECU utilising O2 sensor feedback to adjust the fuel/air mixture - the time constant of the sensor is CRITICAL - as the ability of the ECU to control the fuel/air ratio depends upon the response time of the sensor. A sluggish O2 response time degrades the ECU system performance. Failing O2 sensor symptoms include: increased emissions, increased fuel consumption, hesitation on acceleration, stalling, surging or hunting, rough idling. The O2 sensor is constantly in a state of transition between high & low voltage. Manufacturers call this crossing of the 0.45 volt mark O2 “cross counts”. The more cross counts the oxygen sensor generates, the better the sensor. The higher the cross count, the shorter the time period - and the more responsive the total system. This improved LSH24 lightning oscillation & constant flip-flop back & forth from rich to lean allows the ECU to operate at peak efficiency.
  18. The 15RC ECU is used on O2 sensor equipped V11’s. The 15RC hardware also was used on later Breva’s, Nevada’s, Griso’s & I think the early Stelvio’s - with only the installed software mapping being specific to each model. However Tomchri, just to clarify there is nothing too slow with the Magneti Marelli 15RC ECU - only the original spec LSH15 sensor slow calibration curve input wasn’t able to keep pace with what the 15RC ECU needed to produce a smooth, stable closed loop running state. The LSH24 sensor calibration curve is 10x faster - therefore the fuelling is more accurate - the slow LSH15 sensor input influenced the lurching struggle from too lean, to too rich, back to too lean, again back to too rich ad nauseam... whilst in closed loop range. In fact, whilst the LSH24 is 10x faster - it’s improved speed still can’t match the 15RC’s ECU’s inherent output capability. In fact, any ECU is enhanced by having an O2 sensor to provide feedback input - this enables it to check & analyse that what it is doing (commands) is accurate in accordance to its programming parameters. However, most factory programs in closed loop have just been designed for required emissions & fuel economy. But then again if dyno mapped this emphasis can be modified for whatever the user wants. Read up on Lambda tuning. Whether your bike has a O2 sensor or not - the first thing dyno tuners do is whack a wideband sensor up the pipe to get that essential O2 feedback. But if your bike doesn’t come equipped with O2 - just crack open another IPA & don’t worry ‘bout all this palaver... Only on those models subject to complying with the Euro emission requirements laws.
  19. @KINDOY2 has magnesium wheels adapted... Ooh yum, magnesium sounds nice - always admired the old school gold 18” Marvic’s. Any link or pics Docc...? 😋 A thousand words isn't much help to a mute. Tend to agree with you Mikko - QD’s look so right filling that under void. One small suggestion - try and get the level as perfectly aligned with the sump line as possible - some I’ve seen seem to have an excessively droopy slope downward to the rear wheel.
  20. Okay, sorry for not getting back to this earlier - but got caught up with the usual stuff. So following the two adaptation rides under 3000rpm - I went on a ride into the city of some 45 minutes with plenty of stoplights, roundabouts etc. the bike was an absolute joy - smooth, stable tempo with every manoeuvre, gear change. Then I took the bike out beyond the suburbs to give it some gas. Perfect. What was most notable, rolling off the throttle the bIke has lost all its pops & burbles emitted from the M4’s. Zero. All revs, all gears, downhill coasting from high to low revs - nothing. Buttery smooth. Even after services from various renowned Guzzi mechanics - the bike has never been better. The new Bosch LSH24 0258003805 sensor cost €41.22 - sent from AutoDoc Germany to my friend in the UK for another €20.64 postage & 20% VAT. Friend posted it to me for around £13 all up. (AutoDoc doesn’t send items outside EU to Australia). Anybody who has an O2 equipped V11 with the 15RC ECU should swap in a quality LSH24 sensor. It is such an inexpensive item, easy to swap over - don’t bother with any ECU modifiers until this is done first. Brilliant upgrade. My bike has literally been reborn. Safer, smooth & vigorous. In my view - there’s nothing wrong with the Magneti Marelli 15RC ECU - any suggestion to disable O2 sensor V11’s has been made redundant. The ECU has simply been limited by GIGO - garbage in garbage out. Get rid of those slow crappy old LSH15 sensors! Finally, I wish to give all credit to the post by MotoUbe on Anima Guzzista forum. Thanks to Ube - my bike is as comparably smooth to any Honda or BMW. Cheers fella’s! 👍😎
