No, odd not at all. You would not believe what is fastened, bolted together, secured  and so on with 11 mm nuts here in Europe. Especially we Germans love our 11 mm / 13 mm connections.

Should have said, "odd size for a Guzzi." It's the only place I can think of offhand that uses a 11mm wrench.

Y'all remember carbon tetrachloride? Works even better when heated, for degreasing. Also excellent for extracting dampness from ignition wiring. I still have a Pyrene fire extinguisher. MT of course.  R3~

The only thing odd about 11mm is that it's an odd vs even number. Guzzis have to be the easiest bikes in the world for valve adjustments.

Did a 4 cyl DOHC with shim under buckets once - never again.

Standard thread.

I asked the question poorly.  To reduce the lash you tighten the adjusting screw and to increase it you loosen it?

As an owner who has just done regular checks on a single bike, I've used the same gasket 2-3 times w/o issue. Just make sure the surfaces are wiped clean. Never used a cleaner/solvent and never had one leak. I'm sure Pete (and others) have done many more and will weigh in.

Depends on where you live and how you ride I'd guess. With 8V's I've generally found that the gaskets usually last well, (They are the same design and material to those of the V9/V7'-III.) but the factors that affect their life are climate and riding style.

If you live somewhere where it's hot or ride hard enough to really get the head temperature up on a regular basis the likelihood of leaks increases in a directly comparable way.

What will be more leak prone will be the tampons. Gaskets will usually go round three or so times reliably before they become too stiff, incompressible and frangible. The Tampons are less forgiving. My advice to people is have a set of gaskets and tampons on hand but only use them if you need to. It'll be the Tampons that will weep first.

'Very nicely done, thank you for taking the time to photograph as well as to post this. Given what a PITA valve adjustments have become on some bikes (remove the tupperware, remove the wad of electrical whatnot above the heads, open up the heads, pull assorted cam this-and-that to find what shims you don't have, go to shop to get, go to other shop to get....) the Guzzi approach is damn near zen-like.  If Prizig where to have wandered west now via back roads odds are good he'd have been on something like a V7.

Thanks Pete for the write up it help me a lot ! I did the first service on my 2018 V7III Carbon Shine with 937 miles on it . The right cylinder valves were very tight less than .002 I set the intake at .004 and exhaust at .006 the left cylinder was in spec . Then I checked my 2017 V7III special with 3649 miles that had the first service done around 950 miles at AF1 racing here in Austin and all the valves were still in perfect spec . This was the first time for me to adjust the valves on a Moto Guzzi and I couldn't believe how easy it was .Thanks again Pete !

Cylinder head cover.



Remove screws holding on HT lead cover.





Then remove the cover. Suspenders-snappers will be overjoyed to know it's made of aluminium rather than plastic adding weight and cost to something that ideally should be made of plastic!

Pull off the plug cap and hang the HT lead out of the way. It sits in clips at the top of the head and needs to be popped out to be pulled out of the way.



Undo the three cap screws retaining the rocker cover and remove it.



Remove the spark plugs, (You'll have to remove all the HT lead dross from the other side to achieve this.). Now the best way to proceed is to tie down the front of the bike and jack it up under the sump to get the back wheel off the ground. Once you can turn the wheel stick the bike in top gear and pull the engine over with the rear wheel. Turn the wheel in the direction it rotates when going forwards and watch the inlet valve rocker. You'll see it open the valve and then close. The piston is now on the compression stroke. Pop your finger into the plug 'ole or use a drinking straw through the hole onto the crown of the piston and keep turning the wheel until the straw starts to descend again or air stops pushing past your finger. Jiggle the wheel back and forth until you are confident the straw is very, very close to its highest point, (Achieved when the piston is at TDC.). Note it doesn't have to be exact. A few degrees each way won't make a blind bit of difference. As long as the tappets are on the base circle of the cams it's all good.

Grab yer feeler gauges and adjust the valves by loosening the locknut on the adjuster and turning the adjuster until the gauge is a smooth sliding fit in the gap betwixt rocker and valve.



When you're happy re tighten the lock nut while preventing the adjuster from turning.

Repeat for other valve and then go round the other side of the bike and repeat the entire procedure for the other cylinder. Remember TDC on onecylinder is NOT TDC on the other. Treat each cylinder as a separate entity.

Once adjusted put the rocker covers back on, put the plugs in, reattach the HT leads and replace the lead covers.

Job done.

Note the obvious provision in both head casting and rocker carrier casting for a central spark plug. 4 valves are just around the corner. Why they aren't launching the V85 with the 4V engine is beyond me!





Pete

I appreciate the completeness of this guide. 

question from a newbie here!  I would assume that there is a nut on the crankshaft that could be used to rotate the engine in neutral.  I am also assuming the rationale for jacking up the bike and turning the engine over via the rear wheel is the front cover contains oil.  Hence leaving the front cover in place and rotating the crankshaft via the rear wheel.

Is this true for all Moto Guzzi's?  I recall the WHICH V7 TO BUY? thread that mentioned that some Guzzi's have an oil cooled alternator and some don't.

If we are picking nits, don't forget that the early V7s (MK 1) have a dry alternator with slightly higher electrical output than the later models.  It's really easy to pop out the cover over the alternator and use that to turn the engine over while checking valve lash.  You cannot do that with the wet alternator.

Peter Y.

Which instance would apply to my 2007 Nevada 750?  Is it considered a V7 MK1?

If I remove the front cover, is it dry inside or does it contain oil?

Thanks in advance.

Moto Guzzi Tampons?

What is that?

Any (non-female) tampon knowledge that could be shared would be appreciated.

Ed,

The MkI etc refer to the 1TB models (2012/2013+).

Your 2TB model is pretty close to the 1TB in most ways especially valve adjustment.

Yes you can remove the front cover and spin the motor with a socket.

I'm probably not too far away from the adult diaper stage of life, but knowing I'll never have to change my own tampons is some solace.

Gramma's timeless wisdom about avoiding vices: "If you never try it, you'll never miss it!"  pretty much sums up my philosophy and game plan regarding tampons.

The valve cover is electrically insulated from the rest of the engine by the rubber gaskets and fastener insulators.
I laughed when I saw the grounding contact under the cover, I wonder how many owners complained about electric shocks before that was added.
BTW, you can get your straws for free at McDonalds, that's Guzzi content

Getting ready to do the valves on my V7III Milano.  It is my very first time attempting to adjust valves, but this bike is the bike to try on.

Just want to know the final consensus on intake and exhaust, .004" - .006", .005" - .007", or .006" - .008" ?

The bike's sticker says .006" - .008", but I have read all the above published as appropriate for the V7III


Thanks in advance.
