Update:
 
I had a chat with the GM of the dealer earlier who went through the issues in more detail.
 
The crankshaft support and bearings are damaged because the engine was running with only 1 litter of oil. The damage allows the shaft to move away from the clutch when engaged , hence the reduced friction and constant need for adjustment. I guess that makes more sense now, though I'm not a mechanic so not 100% sure.
 
No definitive answer if it will be covered by warranty yet...

Sounds like the crankshaft thrust washer(s) must be quite fragile if they've worn enough to cause clutch problems. Unless the low oil level caused the thrust surfaces to run dry.
Personally I'd be surprised if bearing wear could affect clutch operation. Worn bearings would surely show up as noise/vibration/rumbling/knocking?
 
Presumably it's possible to pop the alternator cover off and check for any perceptible end float in the crank?

Yes, you should be able to confirm any end float, but it would have to be a lot to affect the clutch operation. If the thrust bearing has completely disintegrated then yes, but surely there would be other bearing failure symptoms at that stage.
 
The thrust bearing would not disappear after a momentary loss of oil pressure.

Can't believe it either, sounds a bit too much like BS.

I would think so. Worth it just to confirm.

How can we collate all these engineering facts/observations/opinions to be of assistance to Antonis who may not be as au fait with the technical side.

 I know I wouldn't be able to argue the toss.

Sorry for bringing up Cars but a common problem with the old 2500 six cylinder Triumphs was worn Crankshaft thrust washers and you could always tell with the engine running by depressing the Clutch and watching the front pully move in and out if the bearings were worn. I would imagine removing the Alternator Cover and operating the clutch with the engine running would have the Alternator Rotor moving in and out in the same fashion if the thrust washers were worn.

Maybe you could learn more about your bike and check engine oil level more frequently?

Hi all, Apologies for taking so long for an update, went on holidays and thought to leave bike problems back in the uk. 

The good news is that MG have agreed to completely replace the engine with a brand new one send from the factory. The bad news is that it takes ages to do that so I still don't have my bike back. Thankfully the dealer gave me a courtesy scooter to commute on for as long as the bike is in the shop. Dealer said today that engine will be here next week and bike should be ready in 2 weeks which will give them enough time to test it too. So a little more patience and hopefully I will have no problems from now on!

I'm not sure how that works with engine number and the V5 though, or how this will affect the value of the bike. Anyone have an idea?

Good for GUZZI standing by a new bike in warranty and doing the right thing. This is what they need to do to prove the warranty is worth anything.

A replacement engine should be sorted with DVLA by dealership as it was faulty manufacture, as for future value it also should not make any difference

Looking elsewhere, it would seem the thrust bearing on the 6 speed V7 is a bit suspect, several have failed, not due to low oil either. Down to clutch adjustment.

MG replaced my V7 engine due to an oil leak. Luckily I didn't need the bike because it was off the road for eight weeks.

I have to say a lot with Guzzi does depend on the dealership working very hard in the background BUT I actually found that Guzzi honoured the recalls that had NOT actually been carried out on my 03 Cali EV and they actually agreed them reasonably quickly ...The irritating thing is they can be slow to react they can also drag their heels.
 
ALL manufactures of vehicles nowadays have issues some can be catastrophic, especially for the owners However the BIG difference is those who buy bikes do it with much more passion than many car owners, IF a bike goes wrong a warranty claim is always something we look at in despair, However there HAS to be a system, dealer checks and reports manufacturer then asks questions and there is a communication and agreement to fix (or not) then the parts need to be sorted and workshop time allocated.....
 
Not an easy thing to deal with when it is YOUR bike and YOU are without it!
 
This is a good result , a new engine, fitted , run it in again and as per the manual check oil levels if unsure ASK the dealership to show you the REGULAR owner checks you ought to do.
 
I remember every bike I have had from every dealer they ALL had the tech guy go through the basics, start,choke,ign, how to undo the seat,tank cap where and how to check oil chain (When I had one of those)
 
This even happened when I bought the V11 Le mans at Twiggers even though they KNEW I had Guzzis , BUT on that the seat off is different to the Cali EV.
 
I never have a problem with them going through these items you can always learn
