Would it be possible to name this paragon of customer service? North London is a bit of a Guzzi desert and I guess they will be in the nearby Herts region?

Great, glad all was sorted and hopefully that should be good. Can you tell us the dealer in question? |

I think that is most likely the bike has been ridden well outside it's envelope, but i will keep an eye out for anything similar. I suspect he has had both wheels off the ground on more than one occasion.

The dealer in question are On your bike Aylesbury.
Main dealer for all Italian marques. All of the team have been great to deal with.

Looks like it's a problem with collapsing swing arm bearings, apparently now beefed up on the new Stelvio

Oh dear
 IMHO, Same routine as before I'm afraid. Back to the dealer, tell them the previous repair has failed, give them the chance to repair it. You can start to build towards rejecting the bike because no one can repair it but take care, that's a huge problem for a dealer who'll be saddled with the duffer. I wouldn't push hard until it gets there, you want them working not scared of lawyers. I would want to know why they believe this is happening. I doubt they'll have a problem telling you, but BS detectors should be switched on. Anything about the new tank being hard to fit would have me asking more. Going against my own advice, does it only smell of petrol after a long or hard run? Is this the stink of St. Greta's box? If that's what it is, (rather than dribbling under the bike when you come to start it first thing), removing the box and going to a normal tank breather might be all it needs. Andy

I'll take the same approach with the dealer. They were very good the last time and I would like to think they will want to sort this out.
Good point about the box. I'm going to monitor the situation, essentially using the bike as normal and see if I have a genuine problem. The dealer knows, and in all likelihood, will see the bike for the first service. Should it be another tank swap, I'll push for a hire bike and additional compensation. It's a shame as I really am happy with the bike.

One other thing I have noticed is the pressure that's building up in the tank. Over the past days on opening the cap, there's a pronounced hiss. Not sure if that's normal?

St. Greta's box.
The tank breather is routed to the coal box so that the demons don't escape and make tree fairys cry or whatever the tree hugging religious nutters think happens with petrol in a lidded container. The pipework and charcoal is a restriction. It becomes even more of a restriction once the charcoal is powdered by vibration and soaked in petrol if you fill the tank high enough for any to go down the breather. The solenoid should open and let the fumes go into the inlet based on FI info, but this can be hit and miss. My V7-850 would basically run out fuel if you rode hard on the open roads but obeyed the village speed limits. Huge vacuum in the tank because it was closed off both at high speed and low. I'd pull the pipes off the canister. Seal the one to the solenoid with a 6mm bolt and cable ties, leave the one from the tank open. No more vacuum in the tank and chance to see if the smell goes too.

That's an interesting point. So you think it's a vacuum rather than pressure?
I'd assumed a positive pressure, potentially worsened by increased temperatures.

Yes vacuum. Falling fuel levels need to pull air in and the restrictions in the breather prevents it. It's the petrol soaked charcoal you can smell. These should be sucked into the engine and burnt, but if the breathing bit doesn't work I can well imagine this doesn't either. The canisters absolutely reek close up. If liquid fuel soaks the charcoal (because no one wants their Enfield (notorious for it) to have a lump on top of the tank to create a dead volume) it literally pours out.
Empty a gallon out of the tank and go for a 50+ mile ride. If there is no smell it's because the empty space above the fuel allows enough breathing and the pipe to the canister is well clear of fluid.

I did a 120 miles ride today. It's not made any difference. My wife thinks I'm a bit paranoid as she says it's barely noticeable, if at all. I'll get the dealer to give it a once over on the first service.

Good plan
 St.Gretas box certainly smells of petrol and the function of the various controls seems to vary from bike to bike. The V7 suffered proper "running out of petrol" moments (cured) which the ASR stupidity (feels like a dodgy coil) made worse. Even Honda CB500's have their moments of funny clicking noises. My Forza and Cub are the first ones with Euro 5 I have not had the urge to "lighten" by letting this stuff accidentally "fall off". If it goes and there is no dripping it's probably fine. Andy

The nice guys at On Yer Bike near Bicester did the 900 mile service today. They've checked out the vent hoses and various entry/exit points on the tank. All's in order.
The bike is fine and a joy to ride. I can't recommend the dealer and team enough. They've been very helpful and so easy to deal with. I mentioned to my wife that they have a limited edition Thruxton for sale. They want £14000. It's second hand but mint. Why don't you get it says the wife......err I like my Guzzi, thanks
