Rest assured you wouldn’t be alone with that predicament . . .

I believe the factory started the switch to roller tappets in the mid 2012.

No "summary of changes" in the newer versions, the main difference between earlier and latest versions being the coverage of more recent models. Up to the V85TT in the latest publication(V.9)

The OP was seeking info on the correct size/pitch presumably to have the proper bolt on hand before dismantling his brakes . . . Nobody is denying the science of metric pitch measurement, but as we get in these very small dimensions and our eyesight is not what it used to be, you'd have a better chance finding the correct pitch with a pitch gauge than a ruler. A measurement with a 0.25 mm difference is pretty hard to discern with a naked eye.

You would most likely have to replace all the rubber bits, hoses, seals, etc. . . and don't forget new tires. But first I would make sure the engine turns over unimpeded by removing the spark plugs and rotating the crankshaft manually. And as an Italian princess being awakened from a 30 year slumber, I'd prolly go over the entire loom and check for the integrity of all the wires insulation and electrical connections.

That would be very, very difficult, I'd venture to say quite an impossible task I recon

Well, since Mr Sheen is a predominantly Australian product, I got another word for y'all. . . Pledge.

I'm currently running T31 Standard on the V11 and just got a set of T32 GT to be mounted on the Griso. Good tires! Amongst the cheapest of all the premium brands, especially when taking advantage of their summer promo rebates . . . (Guzzi content)

Standard or GT?

Fiat, Alfa Romeo, Lancia . . . I got mine from this company here https://cars245.com/en/item/meat-doria-87074-sensor-crankshaft-pulse/ Cheap enough to keep a couple on the shelf. A good read for phase sensor specs and cross references:

MGCycle sells an oil filter access cover tool with a 1/2" drive - could come in handy used in conjunction with a breaker bar . . . https://www.mgcycle.com/index.php?main_page=product_info&products_id=2695:dbbf603ff0e99629dda5d75b6f75f966

Fear not brothers Guzzisti ! The venerable @Kiwi_Roy may not be visiting here any longer but he's still around and active on WG.

As of today both are still listed for sale . . .

@fastaussie There are a couple of them for sale in the Bay Area . . . https://sfbay.craigslist.org/eby/mcy/d/fremont-moto-guzzi-v11-le-mans/7762291334.html https://sfbay.craigslist.org/eby/mcy/d/oakland-2002-moto-guzzi-v11-lemans/7759411232.html
