There's no quick answer to your questions, but you should consider that pressure hose (& probably pump) designed for total immersion in fuel are different from external components.
Mounting a pump inside a tank will be tricky if the tank is not designed for it.
Power and fuel passthroughs across the tank floor need a fuel tight design.
Also the tanks you mentioned were made for a conventional frame, not a spine frame, so fit could be a challenge.

Odd thing voltage to the battery @ 4000 RPM 14.92
Is that 2 high?
12 minutes ago, docc said:Yep, charging too high. Should be 13.8-14.2.
I think it is important to make the grounding of the regulator to the frame/engine/battery perfect.

I've had two cracked gearbox cases (one from a crash). I think it is notable that the center support from the bottom of the Spine Frame was eliminated in the V11 series making the rear-most mounting more vulnerable IMO. I added one back to mine, but it sure makes disassembly difficult . . .
If someone has a cracked gearbox, a guy in UK is virtually giving away the casing.

... voltage drops from 12.5 to 4.5V as soon as i turn on the ignition so looks like i'll be having another Guzzi electrical fault finding session... can't imagine what could have happened to the electrical system in the intervening period.
Electrical connections will degrade over time, and any 12v system is vulnerable to increased resistance from corrosion. Oxygen and Humidity cause this. Imagine how much more trouble a vintage 6v system was. I'd disconnect the ground lead to the gearbox first. Get clean shiny metal to metal faces, re-assembled with grease. Battery terminals next. A voltage drop to 4.5v means a bad battery &/or bad connections.

Could the problem be related to Cash1000's experience?

I suggest a quick troubleshooting test: take the fuel hose off the pressure regulator, point the hose into a tin, and turn on the ignition. You should hear the pump run for a few seconds, and you should see a few ccs of fuel run into the tin.
If not, find out why not.

Got a few shots of contact cleaner in it and cleaned up some of the gunk on the outside edges. Both switches seem to have pretty good action.
I've had good results with electrical switches, after cleaning as you did, by using a generous blob of grease designed for switches.
Lubriplate DS-ES is one of those that is easy to get if you live in USA. It protects switches against effects of hot/cold & wet/dry cycles.

I see that your pump is on top of the spine. Mine is actually underneath, but I imagine that there's no functional difference.
There is also a lot of hoses shown in the picture. As I understand it, the outlet from the pump goes to the filter, then injector, then other injector, then regulator return to tank. There's no other fuel pressure hoses needed.

Picture of the old steel fitting and the new mostly aluminium fitting.
BTW, the original V11 vent is always open, so "burping" doesn't do anything.

Thanks.
Mine is indeed vented and I know it's open because it let's water in.I've never seen water in my bevel box, but I replaced the vent fitting anyway because:
a. It could let water in.
b. It was unnecesarily heavy lump of steel.
c. because I could.

About to pull cover bike is stuck in 6th
There's a lot of info here:
If the selector spring is broken, the only way to change gears I know of is to pull off the cover. Then you can slide the 4 selector forks around to get neutral. Then you turn the cam wheels to match.
BTW a seeger ring is also known as circlip.

Scud posted a picture and description of a way to pressurize the injector. 5 Dec 2016.

I cleaned my injectors, afterward they produced a strong single stream.
How did you test the injectors? I imagine that the spray pattern would change with different pressure and different fluids. I used a spray can of mass airflow sensor cleaner and got a good spray pattern when each injector was momentarily powered. Perhaps your single stream could become a mist at normal pump pressure.

Can somebody explain what this does? I think it is supposed to 'dampen' shocks coming from the rear wheel.
You're right about that assembly dampening driveline shocks. The standard cush drive in the wheel is too stiff to completely do this by itself.

I’ve just found the link to this old tractor’s page... doh! There’re full colour copies of, what looks like, every model!

Your wiring diagrams and Carl Allison's are both good. Thanks to both of you for your efforts 👍

It sounds like the Van Gogh Alive exhibition here last year. An great show about an extraordinary artist with a tortured soul.

On my bike the injectors were held into a plastic housing with two phillips head screws. These screws were retained with locktite.
Are these the screws you are asking about?
Anyway, one way to remove tight screws is to use penetrating oil and heat. Heat softens locktite. With a plastic housing, heat conduction is poor, so heating the screw head with a soldering iron may help. How hot you ask? About 60°C max should be safe. You can hold your finger on 60° for a few seconds without burning.

If it's not the filter gasket then the oil pumps lost its prime...
I used a small hand pump to prime my bike after the sump was off for weeks. I didn't know if it had lost prime, but I thought it wouldn't do any harm. As Phil suggested, I pumped oil into the pick-up tube which pokes down into the sump screen.

During a visit to a wrecking yard, I noticed that some Toyota cars had Denso relays the same size as the V11, so I added them to the cart. I will try them and report back. I expect good things, as Denso is a good brand, and a car electrical system is at least as demanding as a bike.

The world already judges Alex Epstein. He makes absurd claims to make money.
swing arm removal
in Technical Topics
Posted
I'd try fitting the left pivot pin from the inside, so that the pin swages the damaged outer few threads into line. After that, wind that LH pin out enough to fit the swingarm and RH pin.
If you use a tap to recut the threads, you risk having a loose pin if you don't use the correct tolerance tap.
