    (Solved!) Had to get a jump start from roadside assistance; starter motor not cranking after a chilly night; intermitent issue?!

    ...when I pushed the started button, the light's intensity diminished, but the starter motor did not crank. Tried a few times, nothing. Tried again, the starter cranked immediately...

    I had these symptoms on my '03, after the bike sitting unused for too long with the rear drive out. I replaced the 5 pin relay in the forward position, and now all good. B)

    This time I binned the relay, instead of putting it in with all the spares of doubtful function in the monkey paw trap.<_<

    ... think that we will continue to see increasing numbers of V11 parts become No Longer Available. Very common with 20+ year old motorcycles (and cars)...

    True, although there's a more optimistic possibility.

    Moto Guzzi may wish that old V11s are scrapped, so you can buy their latest model, but if customer demand is sufficient, some aftermarket vendor will organize a fresh production run.

    We see this with some vintage car parts.

    And V11 gearbox springs.

    And Roper plates...

    Maybe soon Brembo 16mm brake master cylinder kits.

    Hearing Aids and Riding Care to Share your experience?

    ... Hearing aids..  Do you wear them?  What do you do with them when you ride? I usually wear the best ear plugs I can find online..but that is hit or miss.

    Care to chyme in with your experiences?  

    I wear a thin cotton balaclava that protects my hearing aids as I take my helmet on or off.

    The shoei helmet has a ruff at the sides and back of my neck, and a visor that seals well so wind roar is muted.

    The hearing aid receivers partially block outside noise that doesn't come via the aids, and are set to limit loud noises, so I don't use ear plugs.

    I probably should have when I was younger. :unsure:

    I have some clutch and brake masters in a box. Maybe I'll break one down and measure the piston. MG Cycle also sells the kits based on diameter, but they couldn't tell me what kits to get. I'll probably learn that when I complete my "brake certification training." It would be good to document the appropriate kits in our Encyclopedia of compatible parts. 

    Do you think a preventative rebuild on the brake masters is worth doing - or will these 20year parts still last for a long time with their current seals and such? 

    Some previous discussion here: https://www.v11lemans.com/forums/index.php?/topic/22114-front-brake-master-cylinder-rebuild/#comment-254615

    You need a 16mm kit, given Phil's comments.

    And yes, I think a preventative rebuild is a good idea, especially if the fluid has not been changed every 2 years in the past. I found a rusty spring in my clutch MC. I haven't yet rebuild the front brake MC, so should take my own advice.

    ...Are you aware that Airbus has a program which will eventually see only one pilot aboard an aircraft...

    True, and not just Airbus. Completely autonomous cargo planes with no crew have already transited the Atlantic.

    There is an intermediate step in the development from 2 pilots to 1 pilot. That is a pilot and a dog. The pilot's job is to feed the dog, and the dog is trained to bite the pilot if he tries to touch something.:D

    (No disrespect to pilots or weather gods intended.)

    If I understood correctly, on a B 767, left and right elevator surfaces could be moved in different directions from opposing input from the captain and first officer control columns.

    Yes, many older aircraft designs using cables from the flight deck to the control surfaces had provisions in case there was a mechanical jam or breakage. The aircraft still had to be able to land safely if say the co-pilots cable run jammed. Then there would be an indication that something is wrong, such as the co-pilot not able to move his control column, and the captain using more effort. If there was dual opposing inputs, then a mechanism like a spring cartridge would allow it, but increase the effort for both. This is not unique to the B767, but is not possible on more modern "fly by wire" aircraft.

    There is a little price issue, too. Looking at my navigation app, I'm seeing prices locally from $5.15 to $7.29..

    I guessing that this is the US$ price for a US gallon. 

    If true, for this side of the pacific, $6US buys 3.76 litres. 1 US$ buys $1.47NZ.

    So Chuck's calculator pricing is equivalent to about $2.35NZ per litre, delivered to your plane.

    As for the 44gallon (UK) drum, it is the same size as a 55gallon (US) drum, which is about 200 litres.

    No change.

    The Air France plane had an autopilot disconnect in cruise as it got extreme icing in a super cell. The crew must have been half asleep, and stalled it all the way into the sea. Loss of situational awareness. The pitot icing was gone in seconds, and just re-engaging the autopilot would have saved them.

    Sorry Chuck, didn't mean to hijack the posting from a Weather God.

    At least it wasn't on an Airbus where each pilot hides his controls from the other.

    Nah mate, remember that commercial aircraft are flying on autopilot most of the time.

    Then airline procedure demands that only one pilot is flying if flying manually.

    On an Airbus, if both sidesticks are used at the same time, the inputs are algebraically added (with limits), just the same as manual inputs to B737 control wheels, except digitally instead of hand force.
    If both sidesticks are used, two SIDE STICK PRIORITY lights on the glareshield come on, a loud "DUAL INPUT" message is played every 5 sec, and a post flight report goes back to the airline.

    Not only can both pilots see each other's sidesticks, three computers are monitoring as well. The pilot can't hide on a modern aircraft.

    When I was a young apprentice, I "salvaged" a 25litre drum of 100/130 (green Avgas) from a DC3 going into maintenance, and put it in my Honda CB450.

    It felt faster, so I tested it. It reached 1000rpm more in top gear at the bend on Harewood Road on 100/130 than the "96 Super" of the time. I previously thought that higher octane was only worthwhile with higher compression or a blower, but there it was going faster.

    Obviously there was some other difference than just octane rating for this fuel to give noticably more power. I had just fitted new 1st oversize pistons and rings, and XS650 cans, but otherwise the 450 was standard.

    I know that Avgas has less volatiles to avoid boil-off and vapor lock at altitude, and I assume higher calorific value ingredients which made such a noticable difference.

    Note that avgas is not the same as 100 octane service station pump fuel.

    As for using 100/130 Avgas in a V11, I agree with the comments that the TEL additive, even in the LL (low lead) variant, will harm a catalytic converter and oxygen sensor if fitted. If not fitted, no harm to the engine, and possibly more power.

    ...That stumble is annoying as heck...

    I suspect that a new V11 did not have a 3k snort. @docc do you remember?

    I believe that you should complete Docc's tune-up guide first before tweaking the ECU. TPS setting, timing sensor gap, cylinder synchronization, and slightly looser than book valve clearances are important.

    Also look for signs of a worn timing chain tensioner affecting ignition timing. Point a timing light into the porthole in the bellhousing and watch for erratic movement of the timing mark at various revs.

    @MartyNZ did you replace all the rubbers with drilled ones, or did you alternate. 

    Tim, I fitted three pairs of drilled pucks in alternating recesses. See picture. No problems after 3 years.

    The other 3 pairs I sent to you in 2017/2018. Yours have slightly less rubber removed.

    MartyNZ convinced me on the drilled cush rubbers. He sent me a set just in time for my Scura to have an electrical problem that I ignored for a couple years... I think I'm just gonna replace every other with a drilled one and see how I like it.

    Drilling the cush rubbers was Greg Field's idea. I tried it, and never went back.

    Making a Cushier Cush Drive - Technical Topics - Moto Guzzi V11LeMans.com Forum

    There are 3 places that need lubrication while you have the drive plate off.

    The input spline to the wheel benefits from Kluber Staburags NBU 30 PTM grease, the rubber pucks and retainer plate spacer benefit from dry-lube spray, and the drive plate bore needs waterproof grease.
