If you have sweating and stiffness in a V11 hose, I believe that you should replace it. If original, it is 20 years old now. Make sure that you get the right specification of hose. The correct material for sub 50psi external pressure hose will not last if submerged in fuel. The correct material for hose immersion in a tank will not last outside when exposed to sun and heat. Low pressure hose for carburetors is not suitable for injection systems. A good summary is given here, both for hose and hose clamps. https://www.onallcylinders.com/2021/10/24/buyers-guide-how-to-pick-the-best-flexible-fuel-hose-for-your-vehicle/

Oh boy, this is was an informative read...scary too. I'll be pulling my swing arm maybe next week and will be able to get eyes on this. I have a bracket coming to install, hope I have the frame tabs and no cracks in the tranny.

That’s a pretty large claim. I’d have to disagree. Ball of Confusion, And the band played on… then about a dozen Dylan songs before that but Led Zepplin has great guitar. to each his own tho, it’s all subjective anyway.

I saw this live back in the day. maybe the best song composed in the 20th century?

The fuel pressure is 3 bar (40-45 psi), IIRC. How about using high pressure "fuel injection" style clamps? Otherwise, perhaps your hoses have hardened to the point they will not seal well . . .

This is an important and good read . If you are going to use the crimp type hose clamps , practice using the clamp/tool on a practice hose to get good at this style clamp system. You say your bike has the "in tank" fuel system ? Be careful working around these fittings. You break this stuff and you are going to be ANGRY !

Yes, they require a special tool, maybe $50. I use these connectors a lot on pex piping, but think they are overkill for low pressure fuel lines. I might use them if they were easy to take off, but they are not. They have to be cut off, and too much force might be put on what they are attached to.

These require a special tool to crimp? Are they re-usable? https://www.oetiker.com/en-us/

Factory marks can be incorrect, don't trust them. Best check alignment of shaft for yourself. The original shaft assembly in my Scura could not be aligned correctly & was either badly made or a mismatch of parts.

It can't be a 2002 as they weren't built then. All 8V's, (And all Stelvios use the 8V motor despite the early ones being designated '4V'.) manufactured prior to the middle of 2012 used the flat tappet top end and they all fail. There are no exceptions. Some may last longer before they make a noise than others but make no mistake, they ALL fail. The only cure is to convert to the roller top end and there are four different kits to achieve this depending on year and model of machine. If people would like I can post up my 'Definitive guide to rollerisation' here but someone, presumably a mod, will need to insert the pics as I can't seem to work out how to do that here. Other major factors to be aware of are swingarm and shock linkage bearings which if they haven't been greased by a previous owner will require replacement and it is wise to replace the sump spacer gasket between the sump spacer and the block with one of the thicker aftermarket gaskets available as they tend to blow out around the front oil delivery gallery if the shitty original gasket is kept. Finally, make sure that the previous owner has not used a K&N type air filter and that the drain hoses from the airbox are intact, attached and plugged. This is very important as the 50mm TB's are very sensitive to damage. Also check that the yellow paint on the throttle stop screws is intact and they haven't been fiddled with, few workshops seem to know how to tune a W5AM Guzzi and if the throttlebodies are messed about with by someone who doesn't know what they are doing it is possible to turn them into scrap very easily. They are no longer available as a spare part. The stock mapping is pretty pedestrian. The W5AM has been an open book for well over a decade. There is no need to pay preposterous money for 'Reflashes' as you can swap maps easily and safely using Guzzidiag 'Reader' and 'Writer' programs and there are several aftermarket suppliers who can offer you much improved maps in both closed and open loop format for little or no money. You will need a laptop with Guzzidiag downloaded but you should have that already for your V11. You cannot tune a W5AM bike without it. Just saw your last message. 2012 was the changeover year to roller tappets. Only way to be certain is to lift the rocker cover and look. If it is still a flat tappet bike it will require an 'A' kit to rollerise it.

this was the nicest

Great to see you Tim @nobleswood Today. Great show, as all moto shows in winter are not many gootsie but here they are Cadre was there with one for sale, below. The one above was Enzo's too I think I know this guy's bike, from Indy

Do you like pedal steel? It doesn’t get much better than this, He plays a Strat too.

Johnny knew y’know
