Only LiFePO4. Butch : Lead's dead, baby. Lead's dead. “LiFePO4 batteries are the safest of the lithium batteries, because they will not catch fire, and won’t even overheat. Even if you puncture the battery it will not catch fire. This is a massive upgrade over other lithium batteries, which can overheat and catch fire. LifePO4 batteries have the safest lithium chemistry. They weigh up to 70% lighter than lead acid batteries. AGM batteries will do plenty of damage to your wallet, and are at high risk for becoming damaged themselves if you drain them past 50% capacity. Maintaining them can be difficult as well. LiFePO4 Ionic lithium batteries can be discharged completely with no risk of damage. Charge efficiency: a LiFePO4 battery will reach full charge in 2 hours or less. Self-discharge rate when not in use: Only 2% per month. (Compared to 30% for lead acid batteries). Runtime is higher than lead acid batteries/other lithium batteries. Consistent power: same amount of amperage even when below 50% battery life. No maintenance needed.” https://lithiumhub.com/lifepo4-batteries-what-they-are-and-why-theyre-the-best/

Hey VtwinStorm Move on from AGM. All you’re doing is lugging an anchor around - & imo the old PC545’s are waaay overrated now. These have proved to be superior in every way in a V11 - even with Mike Rich HC pistons. Prismatic cells LiFePO4 battery with BMS (battery management system) is best. https://www.batterybusiness.com.au/store/product_detail/ssb-high-performance-lithium-battery-lh7l-bs Listed as suitable for Bimota 1100 SB6 four cylinder & TM 530 thumper engines - so our relatively lower compression twins are a breeze. So small - so light - in time any initial disbelieving trust issues just eventually evaporate away!

Strewth! Popped in for a curious squiz Well… if we’re posting up eclectic tastes that yet somehow strangely fascinates - I’ll join in on the fun & add my weird odd job lot & …see myself out

No knock sensor - I simply assumed it must have one but if not then - thanks. 👍😎 However, we also mustn’t forget the 15RC variant V11’s. The 15RC ECU of my bike has ample ability to adjust to different fuels - the O2 sensor information in closed loop feedback to the 15RC ECU allows for those fuel quality fine adjustments. Looking further into O2 equipped ECU’s - the STFT used for immediate adjustments is based on the O2 sensor detecting exhaust oxygen content changes (several times a second). LTFT learns from those STFT trends - & the adjusted values are then stored in memory. To wit, ”To adjust, or not to adjust, that is the question”

So with regards to the ignition advance timing parameters… If ignition advance is continuously being trimmed subject to inputs - does the ECU receive any further feedback which in effect ‘checks the accuracy’ of those timing adjustments? Or is this something the knock sensor alone limits? For example - it seems the ECU has the ability to retard timing in response to a change in fuel from say 98 to 91 RON & thus avoid the damaging onset of engine knock automatically. So does this capacity extend to an ability to retard automatically in adapting to being dual plugged? Understanding the granularity of ECU timing advance adjusting trims is intriguing!

Staging is lovely docc & while those lightening holes certainly add a certain cool factor - they do look ruggedly hefty! With gears replacing chains - if there’s any weight difference - is that weight difference in engineering terms normally calculated to be apportioned to the crankshaft assembly - or to the valve train?

Looking forward to everyone’s reports back. Especially Scud’s (btw 4 rellies all pure-bloods Pete, triple vaxxed - bit like drinking Feral’s Hop Hog.. 3 pints are better just to make sure!) 🍺😆

4 relations over here got it - came thru without too much drama Let’s hope according to our #2 top doc… you should pull through no problem https://www.skynews.com.au/australia-news/coronavirus/former-deputy-chief-medical-officer-dr-nick-coatsworth-says-omicron-variant-is-clearly-not-as-threatening-as-influenza/news-story/9f7684fc26256ccccbddf2bf7ec3a142?amp

Kevin Cameron’s latest interesting article. https://www.cycleworld.com/story/blogs/ask-kevin/lean-fuel-mixtures-for-motorcycles/ The Monza is still running better on its passive TJI - more vivacity & power with no problems so far - apart from always needing choke to start whether hot or cold. Anyone know if there is any information on how to easily retard the timing on a 15RC V11 - or is remap required?

M9RR’s absolute best tyres I’ve ever experienced on the ScuraR. Pirelli Angel GT’s initially feel great - light & quick on the front - but that at first impressive feeling certainly wears off before long. Couple of thousand kilometres & front just feels average - can’t abide the rear squaring off so rapidly the fall over the squared lip cornering is meh unenjoyable. Never again. On the other hand these M9RR’s lean angle confidence is awesome - they allow my mind total focus modulating in through exiting the corner - without worrying “will my tyres still stick” & that to me is No.1 priceless! The rear shows no sign of squaring off - great even graduated wear. Curiosity is the only reason why I would try some other tyre - but if someone offered me one choice of tyre for free tyres for life - I’d choose & be happy to stick with the M9RR! Final oily comment - I’ve swapped between 180 & 170 sizes - as far as I’m concerned it’s mostly bull - 170 has less to do with it than the actual profile. The rear M9RR @180 feels just as or even more responsive turning than the AngelGT @170. A 5 millimetres difference each side imo is borderline bolderdash - in comparison to the influence of the actual manufactured tyre’s profile. YMMV but in fact checking the 170 assertion - obviously I’m too insensitive to feel 5ml of chicken strip edge difference - but I sure can feel & appreciate a tyres profile off dead centre straight away! +1 on long term… https://bikereview.com.au/tyre-test-metzeler-sportec-m9-rr-long-term-road-track/

Single cylinder two-strokes… might suffice.

Your output is commendable docc ’Ere… here’s some extra stimulation! 😂 [docc edit: er, "nope." Image deleted]

We always focus on the twin jugs - we shouldn’t overlook the ease of shaft drive Haha! Sometimes it’s enough - just to have a laugh!

The exposure might be a bit under on this tho

One is definitely tilted… & the other is slightly shifted

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.
