    Pretty sure, yes: "All 15M in the USA."

    Not sure I have ever heard of a "2006" V11. Or even a 2005 in the USA. I was thinking the 2005 Scura R was the last of the breed, but have never heard of one of those in the USA . . .

    The Scura R was indeed the last iteration of the breed.

    A handful each to selected European countries only. UK received 4 in total.

    Articles indicated there were only supposed to be 23 made. A reputable Guzzi source refuted that & stated 18 in number only.

    I've built two single spark 1400's. There is a lot of work involved. Torque is prodigious. Outright power increase is minimal. Enlarging the motor produces big difficulties with oil expulsion/crankcase pressurisation. As you say the oil cooling circuits between the single spark and twin spark engines are entirely different and I've never heard an adequate explanation of how these people have addressed that issue.

    The reason why much greater power is well nigh impossible to get is because of the side draft head design, narrow included valve angle and combustion chamber shape. Effect of cam changes will be minimal. I don't doubt that they are fun to ride, I just don't get why people have to make silly claims for them.

    Lots of people been saying there’s no more power to be gotten out of V8’s down at the drags for years…

    Until somebody comes along & proves ‘em wrong! 😂

  3. On one of my other forums I hang out on a biker friend bought this to my attention - as this affects my mates in the UK (I lived there for 15 years) I thought I’d pass the original poster’s message. It’s all supranational lead now - nothing sovereign - so probably be coming everybody’s way.

    I just hope Guzzi hurries up & puts out a V100 LeMans soon because I wanna own one before the world ends!

    —————

    This is over a year old, but I confess I wasn’t aware of it. I must say, I had thought that the ban on ICE (internal combustion engined) bikes had been announced in conjunction with that for cars.

    Stuart Fillingham’s bike channel I’ve only recently come across, confirmation of how long I’ve not been paying much attention to things motorcycle, despite continuously owning at least one bike since 1977.

    I’m feeling genuinely sad, as an understatement, that this ban on petrol powered motorcycles marks the unequivocal end of an era of “the freedom of the open road”, which was afforded to people of all ages, but particularly young people, for around the last century. One of the many advantages of motorcycles, unless you buy something so large that it sacrifices it’s main advantage in traffic, is the ability to weave your way through static jams and out the other side.

    Again, so long as you don’t buy a behemoth like a Victory, or ride around like Valentino Rossi, you’ve the manoeuvrability and economy to get you around quite economically. If you’re willing to put up with very limited power, some small engined machines cost peanuts to run, especially bought 5th hand. These also offer surmountable challenges to a young person, forced to learn how to perform basic maintenance (I’ve never had my bikes serviced by a bike shop, because I couldn’t afford to & very soon didn’t need to).

    If what was going on was a combination of climate change and limitations on availability of so-called fossil fuels, small capacity motorcycles would be a very helpful, partial solution.

    But they’re being banned too, in 2030.

    The only explanation for the behaviour of our government is that it, along with the governments of scores of other countries, have been captured by (or worse, wilfully collaborated with) supranational forces such as we see manifest in the WEF (you’ll be aware that there are multiple other supranational groups who have been operating for long periods of time, about whom we never hear on our captured media & it is likely to they’re the source of WEF’s “marching orders”.

    I don’t know how far down the rabbit hole Stuart Fillingham has got, but he’s a bright person, a former beat policeman (remember those?) & lifelong biker. He knows that climate change as an existential crisis is just a lie, but I don’t know what else he’s worked out.

    He has pointed out something that I’d neglected to realise, and that’s that the imminent loss of access to cheap transport (like small bikes, or Geoff Buys Cars-style, near end of life ICE cars) means that the rural poor will largely not have access to employment. I don’t think any political party has yet pointed this out, and it’s a devastating problem. I imagine it’s objective is to force people off the land and into inadequate, still expensive, rentals of multiple occupation.

    Best wishes

    For clarity in the matter of ECU type, none of the V11 Sports US models came with 15RC nor O2 sensor. 

    Only Euro models!

    If your V11 Sport is a US import, it came with a 15M and no Lambda sensor - so unless it was modified by a PO . . . .

    Correct. 👍😎 No US V11 models. 

    Only the later V11 models destined for European countries, including Britain, Australia. New Zealand.

    The US models missed out on the 15RC ecu which has the O2 sensor closed loop feedback.

    I’d pointed this out previously.

    This is an international forum where folks with v11’s outside the US come seeking information.

    I am sad to hear of Dr Johns passing. Life is often too short. Death does not wait for you to be ready.

    That Dr John did not invent the spine frame doesn't mean what Dr John did was any less impressive. He also did not invent the internal combustion engine. Everything people are doing nowadays is on the backs of those who came before. Arguably Tony Foale didn't "invent" the spine frame either, as bikes have used spine frames before he "invented" it. A better way of phrasing it might be that Tony Foale helped develop the spine frame that we know.

    The Guzzi sideways V twin is a natural fit for a spine frame.

    Everybody who rubbed shoulders with Dr John described him as a kind & generous soul.

    Mother Guzzi has never credited Foale for the spine frame to my knowledge - it’s on the company to own up & compensate Foale if warranted.

    Speculation of nefarious intent has been attributed to the story of Foale & Dr John.

    But does this actually fit with Dr John’s character? It’s patently at odds from those who contributed first hand reports on their Dr John experiences.

    Not really worth a pile of beans 🫘 inasmuch to tarnish Dr John’s generosity, passion & contribution to Moto Guzzi’s racing achievement.

    Dr John sure knew how to extract reliable high power out of his Guzzi’s.

    Bloody legend r.i.p.

  6. With regard to one of the old hands on the forum… Helicopter Jim was one of those that when he spoke I listened intently.

    It was actually one of his quipped comment's years ago that ultimately triggered my own decision to go ahead & install Mike Rich’s hi-comp pistons

    Really valued Helicopter Jim’s input here & am saddened SV40 cut short his 66 years. It was lovely to see his photo & I give Helicopter Jim a respectful salute.

    Another gone r.i.p. 🫡

  7. What’s pivotal is whether our V11’s fuel is of fossil or abiogenic origin.

    As a kid at school I remember I had difficulty imagining the necessary huge numbers of compressed dinosaurs & leaf matter etc that ended up fuelling the billions of cars & trucks & machinery ever made.
    That notion of source for fuel is incredible 

    Abiogenic origin has not only been discovered but seems a tad more sensical

    I found some interesting info from Cameron.  The new Guzzi and my Duc 939 make similar horsepower over the same rev range and I learned a little about some similarities.  

    My Ducati is called an "11 degree" engine, meaning mild cam duration with only 11 degree of overlap.  It seems both bikes have mild overlap but due lightweight valve train, still have high lift cams.  The Guzzi has finger followers whereas the Duc is a desmo.  This gives a wide power band and low emissions.  More overlap would mean peakier power at higher rpms and higher emissions.  The high lift cam still gets good airflow and power.

    I’m going to just add this in here as further KC tech commentary

    With regards to how the bike runs, more gee gees etc.? Would it be a recommended mod.?

    Hi Eamonn

    Your query re MRM hi-comp pistons.

    Yes. Absolutely. I will answer from memory here… you can always check by going over old posts yourself 

    I seem to recall years ago when I ordered my pistons there were a couple of weight versions - one being comparable to oem stock weight in replacement & the other being further lightened. The piston profile of the two were the same tho.

    The V11 combustion chamber differed from previous Guzzi big blocks by having a angled squish band designed into it.
    I won’t try & relay here the details of the benefits this gives but at the time I researched it extensively because I enjoy understanding the nitty gritty (my ocd kicks in) - but essentially it improves air/fuel mixture turbulence & homogenisation than flat squish band at the higher RPM’s which Guzzi was trying to improve upon for the V11 design.

    Remember also it was changing to fuel injection from carburettor too on the V11 models. This was all happening at the time of Aprilia taking ownership as well. I digress.

    However - there seems to have been either a cost cutting exercise going on or an ordering oversight boo-boo stuff up of sorts & the pistons design wasn’t changed to properly match with the angled squish band heads.

    So while the heads squish band surface was angled the piston squish band was flat resulting in an ineffective non-working squish action. This mismatch is the root of the V11 tendency to detonate under certain conditions . I digress again.

    Anyhow Mike Rich spotted the design nuances of the V11 head chamber squish angle & designed his pistons with the same matching angled squish to work properly with the V11 heads which the Guzzi factory had ultimately failed to ever rectify.
    Improved piston chamber turbulence dampens detonation occurring & allowed a slightly higher compression ratio to be achieved as well with Mike’s hi-comp design.

    Whew! Sorry that the basic backstory from memory took so long Eamonn.

    Anyhooo… at the time I think a member called helicopterJim had previously installed MRM pistons & his positive commentary on his experience probably influenced my own decision to go ahead with Mike’s pistons.

    I chose the standard weight MRM pistons as I didn’t want to be bothered with any extra hassle of balancing work costs.

    I noted Pete Roper rating Guzzi conrods as very strong, very good & so had no desire to additionally fork out for Carillo’s in that case.

    The piston’s had a noticeably positive impact on installation. A slightly sharper bark with a more ‘awake’ feel & pulls harder thru midrange & sustains it longer imo. The occasional detonation rattle reduced to almost never - maybe once in a year of riding I’d notice a little rattle rattle for a second or so… that’s it even in hot 100F days. And that was before a better Bosch O2 sensor which improved the ECU control.

    My bike has the 15RC ECU so it continually trims the fuel when changes are made so it has capacity to recalibrate itself to it’s desired Lambda ratio in time.

    I seem to recall American V11 owners who installed Mike’s pistons without retuning their ECU’s & their bike’s coped fine with improvement but maybe others can confirm this recollection.

    In short - go ahead & install the pistons. They are an improvement. Oh, I just remembered - they are forged & a little clickety clackety mechanically louder for a couple of minutes until the combustion heat expands them just ever so slightly & that mechanical clatter completely disappears.

    Hope that helps

  10. "Let not any one pacify his conscience by the delusion that he can do no harm if he takes no part, and forms no opinion. Bad men need nothing more to compass their ends, than that good men should look on and do nothing. He is not a good man who, without a protest, allows wrong to be committed in his name, and with the means which he helps to supply, because he will not trouble himself to use his mind on the subject."

    Abiogenic Deep Origin of Hydrocarbons and Oil and Gas Deposits Formation

    "The theory of the abiogenic deep origin of hydrocarbons recognizes that the petroleum is a primordial material of deep origin [Kutcherov, Krayushkin 2010]. This theory explains that hydrocarbon compounds generate in the asthenosphere of the Earth & migrate through the deep faults into the crust of the Earth. There they form oil & gas deposits in any kind of rock in any kind of the structural position (Fig. 1). Thus the accumulation of oil & gas is considered as a part of the natural process of the Earth’s outgrassing, responsible for creation of its hydrosphere, atmosphere & biosphere. Until recently the obstacle to accept the theory of the abyssal abiogenic origin of hydrocarbons was the lack of the reliable & reproducible experimental results confirming the possibility of the synthesis of complex hydrocarbon systems under the conditions of the asthenosphere of planet earth."
