Duplicate shelves is the obvious answer, then you have twice the chance of finding stuff later. Down side is you need a shed twice the size.

Ken, I just LOVE it that you're a "Moderator".  Big smile

Well, maybe they are, in the sense that when the time comes, as it must, to deal with them, a delicate 
touch and a modicum of forward planning go a long way in avoiding a complete mess.
This is best learned early on, but then it becomes quite manageable.

Another question please - - with the wheels off the ground, if I rotate the rear wheel back and forwards a quarter of a turn quickly, it feels like there is a lot of play in the system. Is this a feature of the torque converter on the Convert, or is it a symptom of something amiss?

All Guzzi shaft drives have considerable movement like that in the back wheel. Can't speak for the Convert in detail though.

easy to check the splined shaft the Convert has more splines than standard ...these WILL wear if it gets dry a good dollop of lithium grease check yearly ...one part the owners often miss ....Another top tip on all bikes is to pull and grease the front engine bolt IF you use a similar sized bolt to drift it out it holds the engine in place you do not have to pull it right out to grease it ....

Another couple of questions please;
When I bought the bike I was told it had an uprated alternator fitted, so I removed the cover to have a look, and  it does appear to have the uprated alternator (i think). The alternator cover was bedded on some black liquid gasket stuff - is this necessary when I put the cover back on? Can't see any sign of an OE gasket on the parts list.

Second question, the choke worked fine before I started fiddling with the bike, but now the choke lever will not flip up (poor description I know). The cables seem to move OK at the carbs, so I assume it is something amiss in the body of the choke control mounted on the LH cylinder, although I can't see that I have done anything to affect that, and I am not too sure how it comes apart  Any suggestions as to how I resolve this?

Any thanks.

I'm thinking that it is just the std pan cover for the alternator, either in plastic or alloy - if you are lucky. I've never seen one glued on befroe. Normally you just undo the four screws and pop it an its spacer off as you wish. It's pretty much open to the elements around the edge.

On the flip top choke (enricher). As in you can't lift it all the way up, or it won't stay in the fully open position? The latter is not unusual as they wear. You can just take it off and file it a bit to get a new flat for it to stay open (another lousy description - sorry).If it won't actually pull all of the way up you'll need to check cable adjustment and freedom for everything to slide OK - cables and enricher plungers. Having the plungers seat properly once warm is critical to good running of course.

It all comes to bits quite simply.

Following assumes the same as V50:

Does the lever move but just not stay up? If so it's easy. Just file the white plastic bit that contacts the body when the lever is pulled so it goes a bit further over centre. Hard to describe but you'll see what I mean when you look at it. Two minute job.

If that's not it, you need to take the choke plungers off the carbs and put the whole lot on the bench to dismantle it. On mine the cables were in an awful state so I made new ones.

As I said, assuming the same setup as mine.

Before you go filing anything on your choke lever, check for the obvious - it's entirely possible (indeed, likely) that the ferrule on the cable outer has jammed somewhere - possibly on the lip of the adjuster part - so the cable is already under tension, and won't 'open' any further. Happens with throttle cables, just the same, when 'fiddling'  (o:

It's an alloy cover, but there is no spacer, it's just screwed to the engine front cover.
The choke lever will barely move at all. Does checking the plungers involve taking the carbs apart or is it relatively easy to do?

The alloy cover - as standard - has no gasket. Some sources recommend fitting the plastic 'spacer' (GU18001150) from those bikes which have a plastic alloy cover. The idea being to allow for more 'breathing/cooling' room, There is, apparently, a 'deeper' alternator cover, intended for those bikes fitted with an alternate alternate. No way of knowing what you have - part number engraved in the inside of the cover?

Choke lever - check under the rubber cable covers at the carb body (and at the rear of the choke lever assembly) to see if the cable has jammed. If you managed to get the choke NOT working WITHOUT taking the carbs apart then it might reasonably follow that you can get it back to working without doing so, too. Be patient, Follow the cable runs, check each choke cable to see that it is seated correctly, etc.

In both cases, a parts diagram will be useful to you:

Good diagram of the carbs, assuming you have standard fittings, here: https://www.dellorto.co.uk/product-category/dellorto-motorcycle-carburettors-parts/dellorto-vintage-carburettors-and-parts/vhb-vhbz-vhbt-parts/
