Hmmm… product for leather protection …or protective leather products? 🤓

First owner of my Scura R was a Manxman - it was only after testing its limits on a few laps around the TT course that he traded it back in for an Aprilia with Paul Dedman. After finalising deal with Paul I’d requested his contact & in speaking with him - I remember him saying he’d just wished it had more top end speed!! Guess some guy’s always look for more if it’s out there… Anyhoo I really dig Ashley Law competed the TT on a V11 Tenni tho!

Yup. I’m just more comfortable conjecturing odds & dots Ratso88 than the perpetual myth alternative. Your observation - Guzzi riders being pretty thin on the ground. Absolutely! Even less… Dr’s! Dr John - Mighty Scura could! But sure, you might be right & meet a guy - some Dr - who really knows.

(Stock Griso motor or the Mighty Scura engine…?) For all those who may have missed this… https://www.mgnoc.com/print/print_article_ask_the_wrench.html

Okay… so let’s drill down just a little more here… Mike Rich remembers doing those heads & they ended up producing some of the best flow figures he’d ever produced right. Mike also keeps those flow figures in his records but somehow doesn’t seem to mention to Chuck when he rang whether he also keeps the record of whoever it was who placed the order (yeah right). I’d propose that client discretion was likely Mike’s policy in speaking to Chuck. Mike also indicated he didn’t build the motor - it was presumably put together by the owner. Along with the order of Mike’s titanium pushrods remember. Hmmm. This some dumb Dr sure seems to know what he’s doing. (How many Dr’s do you know who are also mechanically minded - but I digress). Mike also happens to be based in Newfoundland PA. Chuck believes Dr is from New Hampshire because… Okay - let’s stay with that for a moment. New Hampshire - where is that? Let’s search Google maps. Oh, the capital Concord happens to be a mere 320 miles North-East away from Mike’s… Hmmm - so what are those odds? This mystery Dr who just so happens to have conceived & produced the most mental 2-valver Pete Roper has ever popped a scabby leg over. It’s all conjecture - but it’s all about the odds here & whether they stack up. So let’s see if we can find someone - a Dr - who has the requisite knowledge to produce such legendary performance as is the wit of the Mighty Scura. So here we arrive at the confluence - it also just so happens that a mere 120 miles South of Mike Rich is one of the best places to live in Pennsylvania - a leafy suburb called West Chester. Also the home of a Dr John Wittner. That’s more than a mere happenstance. A Dr - the original owner/developer of the Mighty Scura. Coincidence? Yeah right.

Good golly! Is she gapping those jugs?

I seem to recall it’s often been said… a Dr from over East. Are you absolutely sure it’s New Hampshire Chuck? Do we all really think this superlative performance is just the result of some lucky random act of someone pulling together a few selected parts? Or is it the refined outcome of an experienced masterful intellect? Let’s hear again from someone who isn’t so easily impressed… The Mighty Scura would pop up with no clutch in either of the lower two and not much more than a stroke in third if approached in anger. It is a stupidly, stupidly fun motorbike. So let’s sleuth this out a little more… • Stupendous performance • From a Guzzi • A Dr Hmmm… what would be the odds that there are two Dr’s out East that somehow know how to produce more awesome street power than anyone else outta a spiney Guzzi? Ha! I’ll tell you that answer - nil, zilch. So Chuck - the question has to be asked, “Are you sure that Dr isn’t from West Chester?” A Guzzi. A Dr. Maybe East - like in West Chester Pennsylvania.

A few attempts may have gone a wee bit awry So getting back in keeping alive the spirit of the thread… Gratuitous Pics of Girls + Guzzi

Scud - let it sink in…

Any current thinking plans for those airbox openings - extensions, stock, Phil A’s teardrops…?

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? 🤔
