ScuRoo

How so…? Ps. Great mural for a dark Gootsie!

What stopped you..?

Wrenchin.. Welcome aboard Ratso88! 👍😎 You’re a very, very fortunate man - it’s been proselytised here over the years your new to you Mighty Scura is the absolute numero uno, most complete, powerful 2v square head ever perfected streetwise by Guzzidom’s Archangel Michael - hence attributively blessed with the eloquent moniker Mighty Scura. It is by faith we chosen few believe…

Wondering if Colt going to show us that fabled power wheelie… 🤔

Huh? Why? SEX of course! This exact Classic shot initially hooked me… after having been psychologically primed by following events… Recently returned from my older brother’s funeral - he was the good, sensible, clean living one. Dead at fifty - stomach cancer. Dirt bikes busted my teen bones, family urged ‘keep off ‘em - you’re gonna kill yourself’! So after my brother, with a GS mate goading ‘get back in the saddle’ - I couldn’t see the point preserving my skin just for bloody cancer or some-such to do me down. From the (then) new V7 - googled older Guzzi’s, & came across the V11… Damn! Smitten on ‘puter looks alone! Tracked my Scura R down on the Isle of Man - it’s delivery was the first V11 I’d ever seen - in all her voluptuous flesh! Like a well-thumbed Penthouse centrefold vision rolling down the ramp - a slightly breathless moment & I’ve never tired of riding her since! Mae West said it best. “Sex is emotion in motion.” 👍😎

You’ve already got a Tenni… so makes sense keep that fairly original. 👍 If I had a scruffy 2nd V11 without the emotional attachment - I’d feel free to do any goddamn change I ever fancied… To hell with stock - when you’ve got two have some fun & hop it up! Experiment anywhere along the range between GB Trofeo & Church of Choppers! You might end up with something you love even more than your stock Tenni! 👍😎

Yikes! Wind that sucker out man - it’s virtually lugging - I almost had to look away. Don’t be afraid to wring it’s scruffy neck! Mountains, mountains, mountains! Aah!

Seems pretty clear. Care to continue refuting?

Guzzi’s been learning for years - at least since first 15RC with O2 sensor models! Closed loop = learning!

Speed of LSH24 input. -> at optimum temperature of less than 600 °C the sensor responds in less than 50 ms. The 15RC ECU’s subsequent fuel modulation response is even faster - much faster! “Consider that the clock speed of some modern ECUs is 40 mHz; that is, the computer moves through 40 million switching states per second. Keep guessing - but it’s no mystery.

You LP - amongst others have tried everything & are still failing at pinning down the root cause. Yet - because there was simply NO consensus on this English speaking forum (& others) frustrated, I looked further afield to research what the Italians were discussing on their forums years ago about the same problem. Nb., ‘years ago’. They - via Ube’s Fiat research & Guzzi knowledge - found the cause for their bikes behavioural issues. The overwhelming single “fix” of many was the simple O2 sensor change. Go read their experience’s for yourself. It simply allows the ECU to do its job better. All those issues were able to be adjusted & were in a nanosecond, subsequently dialled out by the now better performing ECU. The previous slow oem LSH15 incurred the G.I.G.O. of the fuelling modulation by the ECU. Once that single sensor input into the ECU was speeded up by the vastly improved LSH24 cycle rate speed the ECU is infinitely able to adapt appropriately & adjust the fuelling more accurately - hence the surging, stumble, hiccup on constant throttle was able to be adjusted out of the system. It’s not a problem that just affected V11’s alone - the same ‘surging, stumble, or hiccup on a constant throttle’ - call it what you like - occurred on the European smallblock Breva’s, Nevada’s & V7 Classic’s - as well as affecting various bigblock Bellagio’s, Breva’s, California’s, Griso’s etc. LP you know a hell of a lot more engineering than myself - but on this I’m afraid your eyes are simply blinkered. Why? We all have foibles I suppose. Disbelief at the simplicity? If like me you ever trawl back over old posts - way back before Guzzidiag days - back when there were plenty of discussions about Power Commanders & Cliff’s MyECU & whether these would help get rid of the issues. I read everything because I had the same issues, but now, I’m of the opinion it was all just blinded bulldust - the cure had simply been ‘lost in translation’ & didn’t make it over the pond because the Americans don’t have O2 sensors. The 15RC simply moved the game on. Ube & the Italian Guzzista knew all along. SimoneV11 - he knew! So after all that... who’s going to disable their O2 sensor on their new V100 Mandello? Huh? 🤔

...a properly informed 15RC dials both the stumble & surging on constant throttle out. That’s the modern ECU’s raison d’ètre - the beauty of closed-loop adaptability. Nothing to do with valve gaps - or Titanium maps - that’s all just looking for a black cat in a dark room that isn’t there! Try it & see...

🦀🦐🦞🦀 Nuthin’ wrong with a bit of seafood! Seen a lot of blokes with a missus’ with an ‘enormous wheelbase and there is really pretty much nothing that can be done about it’ looking just as you say. Still, those blokes keep going there... https://www.motorradonline.de/naked-bike/blacktrack-motors-bt-05-cento-moto-guzzi-griso/

...even the Guareschi’s GCV is getting customised now! €118,000 as you do!

Any cheapo Carc but would probably target the Bellagio preferably - only just to get that full re-worked GC Varano custom transformation. Phwoarrr! https://fb.watch/aeerBrKpmO/

I’d only have one as a base... https://fb.watch/ae84wioOts/

I’ll follow with interest. Your enthusiasm & skills in fettling V11’s are fantastically admirable Scud - & your advocacy on drilling cush rubbers is intriguing. I remember reading Greg’s original post many, many years ago - with benefits of the drive being made cushier! So refreshing myself again on the cush subject, various posts stood out... MartyNZ, “I agree with him that the V11 is improved, and the drive train should last longer, with a cushier cush drive. But I don't share his view that engine braking causes damage to the wheel drive spline. I think that each 530cc piston slamming torque down the drive train every engine rev is the main reason for spline wear.” Jim in NZ, “The original design was OK, but the rubbers are very hard. I didn't drill mine, but I took out every alternate rubber wedge. I also regularly clean the whole cush drive and grease the centre bearing every 10,000km service. The advantage is that you can feel that the cush drive is a bit softer every time you change gear, with less abrupt take-up of the power. This must (by my reasoning) be kinder to the entire drive train fromgearbox to tyres.” LowRyter, “OK, the idea of drilling the cush rubber is to take shock out of the driveline for the purpose of a smoother ride or preventing driveline failure.” docc, “Seems the idea is all about cushioning the drive line.” Jim in NZ, “Yep, the idea is about cushioning the drive line, and I'm sure it will reduce stresses on all components during hard acceleration, wheelies, clutchless gear changes, unintentionally jiggling the throttle as you go over a bumpy road, and so on.“ LuckyPhil, “I dont really like the idea of removing rubbers because it means that the torque is now transmitted through only half the metal drive blades” Etc., etc. Now having read all that on the benefits of cushioning the drivetrain & even LP’s concern on torque being transmitted... If this all makes so much sense - where is the logic in then increasing “slamming torque down the valve train every engine rev” through to the drive splines - & with torque backlash directly transmitted back again by the very installation of direct drive timing gears? Isn’t this a tad oxymoronic - anyone else see the dichotomy here? I’m left scratching my head over all this... WTH - does this mean drive splines are more delicate than the cam/ drive train?

"Okay, Houston... we've had a problem here.” https://www.abc.net.au/science/k2/moments/gmis9906.htm Your US model V11 didn’t come with the O2 sensor p6x - which creates the closed-loop feedback to the ECU refining the STFT & LTFT functions. As Mr Cameron pointed out, “If there is an oxygen sensor in the exhaust system, it detects any deviation from the desired mixture and the ECU corrects it.” The Italian’s discovered the MG oem sensor was flawed (as did Fiat). Only relevant for those V11’s 15RC O2 equipped - swapping the sensor unleashes the ECU to perform optimally. Good luck with tyre!

Ha! Boxing Day temp downunder... funny thing is we still give each other Xmas cards portraying Santa snow scenes! 🤤
