Yamaha XSR900 GP - Wow! want one????
ScuRoo replied to p6x's topic in Special place for banter and conversation
Brother-in-law traded his Ducati Monster in on a MT09 with Akrapovic exhaust - so I recently had opportunity to test it. That triple is impressive. Ugly as only a mother could love - but the motor is a peach. if you get the chance to try - don’t pass on it -

For those wondering whether you have a 15M or a 15RC ECU - it’s very simple to identify. Don't bother looking at the ECU & unpeeling labels under labels & scratching your head or arse. a) Look in the mirror instead. If you’re a Yank (& don’t possess a passport) you have a 15M ECU USA imported V11. And simply move along nothing to see here same with owners of the earlier V11 sans O2 models. Don’t forget this is still an international forum fella’s… it was only the later model European V11’s (& other exported to countries) which had the upgraded 15RC ECU which had additional Closed Loop adaptability. b) If not sure you’re a Yank - get on your knees & look for a O2 sensor as I’ve circled in docc’s diagram above. If your V11 comes equipped with an O2 sensor inserted - you can be 99% confident your ECU is the 15RC closed loop adaptive version. (The 15RC was not exclusively for the V11 but was also utilised on other Guzzi O2 sensor equipped models. The base map was just tailored to suit those other models). c) There’s plenty of opinions from those that don’t own V11’s with O2 sensor closed loop adaptability - these opinions seem to veer towards disabling the O2 sensor as they are only simple narrow band sensors designed for fuel economy or emissions only &/or add unnecessary complexity etc etc. I disagree completely with these notions. The 15RC closed loop adaptability with STFT & LTFT trimming isn’t a backwards step in design. It’s a lovely plus plus on top of the base map - when the throttle is whacked open it operates just the same as the 15M base map as it’s now in open loop mode - but has the added closed loop constant throttle closed loop fine tuning. There is zero problem with the 15RC ECU it’s lightening fast in response times - the original root cause problemo was “the LSH15 probe has such a slow response time to the variation of the exhaust gases” …“the LSH24 instead has a very good sensitivity and a response time equivalent to the reading interval of the ECU.” The 15RC ECU. Don't disable in trying to cure any hiccup stumble or poor running problems. Just simply change the bloody O2 sensor to the improved LSH24 and you’ll have all the open loop 15M provides plus more with closed loop adaptability - which auto tunes out… any hiccup stumble or poor running problems! If this doesn’t make perfect sense folks then go & rip out all your O2 sensors from every other vehicle you own - even butcher the V100 Mandello with its closed loop adaptability O2 sensors. It’s clearly too complex - which is probably a bad thing. -

Here’s my tip. Don’t eliminate the 15RC ECU’s closed loop ability by disabling the O2 sensor. Do not disable the 15RC closed loop adjustability - just change the Guzzi factory installed O2 sensor which was found to be inadequate - with the Bosch improved LSH24 sensor upgrade. I strongly advise you do this before anything else. Years ago I too was frustrated & went searching on foreign sites for possibly overlooked solutions. I’ll leave this translation with you from what I originally tracked down on an Italian Guzzi forum. I can’t recall how many pages were laboriously translated (literally hundreds), but eventually found this gem discussing the root problem - acted on the advice as it was both a) inexpensive b) easy (what’s not to like?) & c) made the most succinct sense - & found I’d hit the jackpot. Hiccup free 100%. Perfect. Translating Anima Guzzista there was a highly respected Italian Guzzi mechanic (Ube) known as Motoube on Anima Guzzista forum who clearly stated the original root of the problem: “the probe used by Guzzi corresponds to a BOSH probe which has certain characteristics corresponding to the BOSH specification "LSH15", in jargon called the LSh15 calibration curve this probe was used on cars starting from 1992/93, it was immediately seen that its sensitivity and response speed were INADEQUATE TO THE REAL CONDITIONS OF USE OF THE VEHICLE. BOSCH ran for cover and created the probe with the LSH24 calibration curve. much much faster and much much more sensitive. realize that the LSH15 probe has such a slow response time to the variation of the exhaust gases that the control unit takes a thousand or more readings of the lambda value .... the LSH24 instead has a very good sensitivity and a response time equivalent to the reading interval of the ECU.” -
Dunno what prices are like in the US market… but that looks like a steal

Your welcome 😂 Yeah been er’… ‘moderated’ a couple of times…

Yeah nah maaate The bloody roos are manageable unless the dawn sun is in ‘yer eyes… altho’ the tiger snakes can be fairly stressful flicking up from ‘yer wheels & climbing into the engine bay only to reappear pissed off on refuelling at the next Golden Fleece roadhouse On a couple occasions riding I’ve had to deal with bush chooks which can be as unpredictable as a epileptic spastic on New Year’s Eve But those angry drop bears are what I usually keep my eyes out for - you’ll be farked if they time it right & get ahold of you Luckily I don’t live out by Ayer’s Rock - the dingoes out there are bloody rug rat killers Strewth! Yeah mate..

Actually there’s about 1500 degrees of difference between fog and dew One is ground level 😏

Aloha! What’s your experience? I haven’t had the opportunity to ride the island… but years ago, I did ride with a couple of mates up to Big Bear outside Los Angeles and the dew at 6,800 feet is bad. Dew at any level is terribly treacherous. Here’s the opening lines from a magazine review by Robert Smith. “One the most memorable and exhilarating rides of my motorcycling life was on a Guzzi: a race-tuned 850 Le Mans Mk1. I rode it from Ha’iku, Maui (close to sea level) up to the Haleakala Park entrance at 6,800 feet on the volcano’s switchback access road, and back down again. With a race cam, lightened flywheels, flowed head, Bub exhaust and flat-slide Mikunis, that baby really flew, handled precisely and would stop on, if not a dime, certainly a nickel. But what was so seductive was the way the motor loved to rev. Below 3,000 rpm, it wouldn’t have pulled a fly off a cow patty; but when it came on the cam, it surged to the red line with a rush of booming power; but on closing the throttle, all was uncannily smooth and calm.” Uncannily smooth and calm… stay strong Lahaina 💪 https://cdnbkr.ca/3893-2-motorcycle-review/moto-guzzi-breva-1200-2008/

It’s quite clear you’re on the right track LP. There is a conspiracy. But there’s nothing theoretical about it. However if you’re not comfortable with conspiracy theorist - the mind numbing alternative is being a ‘Coincidence theorist’ 🤣
