    Are you for real gstallons?

    Anyhoo.. seems if everyone’s more or less on board with Jaap’s sentiment - myself included - I’m not taking umbrage so I’ll just easily move the needle onto the next track…

    Ah Bob Dylan. Classic. Old political songs are more palatable than fresh protest presumably.

    Always enjoyed contemplating what Bob had to croon - #1.

    Once had an AMG sharing a Eurotunnel carriage returning to the UK with Eric Clapton & his then bright new yellow 575M Maranello & passed the journey time chatting. He’d been enjoying tapping the performance by himself on the glorious roads of France for a few days…

    His contented smile struck me when I asked how much horsepower it had, “Dunno” grinning he added, “A lot!”

    Exactly. Lithium batteries aren't some panacea for all of us.

    I acknowledge your experience sticking with AGM - but it’s also worth seeing the snowmobile guys er.., gelling well with them. 🤤

    They obviously can work just fine in subzero conditions - & speaks volumes as it would be more life threatening to get stranded out woop woop in the snow!

    But as you say… “YMMV”

    Nasty Hiccup

    HI All, just cruised through this thread.   Have been having increasingly this hiccup issue the last several thousand kms.  Bike runs and idles fine no hiccups until you start moving.  Its never when im heavy on throttle, only off or coming off the power or at neutral steady throttle cruising.   Its gotten bad enough that its a distraction while riding, and will occasional cough the bike into dying at a light when I rev a bit pro to starting off (love hearing the Guzzi sound of course).  

    Anyway, seems like there is no clean solution.  Not sure where I might get those relays these days guess ill try eBay.  

    Anybody Ive ever talked to thought maybe the bike is just running lean, but its more than that and I never had an issue in the for 15 years of owning the bike soooo..   

    Thanks for the thread all, and if anybody seea any reason I might be barking down the wrong road please say so.  At this point ill replace the TPS, fuse and see where it gets me!

     

     

    The symptom’s a ‘hiccup’ - but the actual cause is a ‘brain fart’.

    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.”

    So, I rode to work tonight,  and it's going to dip into 36F.

    I charged the battery very quickly before I set off a couple of hours ago.

    At what temperature does this Odyssey battery make the V11 harder to start?

    I think the CCA is 170...sweating a little bit atm with such a big engine and such cold temperatures...I want to avoid a no start/tow in the morning when my shift ends, if possible...

    Any wisdom is appreciated. 

    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!

    Ghezzi-Brian ECU for the V11 - anyone knows "Centraline Rapid-Bike"?

    The V11 ecu does not have these capabilities. No knock sensor and no ability to adjust for different fuels. Thats a few generations on from the V11 15M ecu.

    Ciao 

    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,

    Basically it has base fuel and ignition maps ( as well as start enrichment and a few others) as all systems do and it adds trim values to the base maps dependent on atmospheric and operating conditions. So engine temp, Baro pressure, inlet air temp etc. It also takes commands from your right wrist via the TPS and the known engine rpm looks at what the base map is saying and all the environmental trims and injects the appropriate amount of fuel and applies the appropriate amount of ignition advance. As environmental conditions change such as Inlet air temp, engine temp, baro pressure so does the amount of fuel injected and the amount of ignition advance. It's all done in "real time". It's a very capable system and doesn't need any do dads and hang ons to do it job. 

    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!

    My  :notworthy:  Joe Caruso timing gears and relieved cam bushing came today, one week shipped from the heart of England. I have never received anything packed this well, or dealt with anyone finer than Joe. :thumbsup:

    The pieces look awesome! :luigi:

    IMG_6896.jpg

    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?

    Also, FWIW, Joe told me all of the V11 gear sets in this run are already spoken for.

    Looking forward to everyone’s reports back.

    Especially Scud’s
