Lothar,
I will go against the current by saying this:
I think I wrote it before: just don't sell it. It is a beautiful bike. Let the rivet counters count the rivets and money on their specimen, and let the rest of us, ride our bikes. Don't let them story-tell you into tricking you into off-loading your beautiful SFC1000 for nil. They will gain on it asap. The guy who bought my former RGS from me, did exactly that by telling me he had no money, he was sooo interested, never wanting to sell it bla bla bla, and I was naive enough to believe him. Of course he sold it on real fast and made a good amount of money. But that was his luck, and I don't mind. Don't let anyone say things like: Oh, but demand is less, it is not a real SFC, it is not a true Laverda which is of course in their view a 180 degree etc. Just don't accept that crap. It is utterly nonsense. The first Laverda 1000 engine was a 120 degree, and the last real Laverda 1000 was a 120 degree. So make of that what you want. I am staying 120 degree. Better and later and more development and implementation of so many updates and parts. Hmm: gearbox, frame, clutch, cylinderhead, ignition, charging system, brakes and so on and so on. Oh well, a lot of the 180 people wants those parts. Guess why? Because they are better. Why not? What bike did they come from? a Laverda 1000 120 degree RGS series (and possibly a Jota 120). But of course each to his own. That is clear. So no worries. But should we then all split up every 120 degree 1000 Laverda's into spares for the rest? Of course not. "Oh, but a real Laverda is an orange 180 Jota". Hmm... Maybe there are more orange 180 Jota's than they ever built in the UK and in Italy. And the real connoisseurs say it is a silver or gold Jota (or what ever). Who cares? As long as you get the Laverda YOU want. But personally, I
DO NOT like the conversion from 120 degree, to 180. Those people KILL beautiful Laverda's. Okay, back to the sale. Oh no, but wait: this IS a remark of why a beautiful Laverda SFC1000 is apparently worth nil. Even a scrap bike like honda 750 four with a single overhead cam is suddenly worth more in so-called specialists minds, who suck blood from seemingly knowing what anything is worth these days. They have to justify the "trends", the "market", and in reality, they protect their own income. Cheap or expensive. They will never get my respect. They don't bring ANYTHING to the table of Laverda, nor anything else for that matter. This is in my humble view very much a British phenomenon, but goes elsewhere too. Then there is the story-telling: Oh, but Massimo once saw this bike when he passed by on the street, and it was once touched by Mr. XXX who raced an XXX on XXX track, or something along those lines. Suddenly, the same bike, same parts, same everything, is worth SO much more... I mean come on, use the brains. Every single Laverda was built with passion, sometimes leading to a little too much going on, strikes planned ahead etc. etc. 
Do people really think that Massimo would have looked down at improvements or attempts to improve or stabilise? Of course not. I seriously think he would have looked carefully at them and said something like: Hmm. Interesting, good idea, good improvement. And then maybe he would have even taken a ride on the bike and commented on the changes. That is what I believe, because Massimo was a gentleman and a creator, not a rivet counter or a person who estimate values on other peoples stuff. No, he was never seeing the bike as a final bike, but as a steady on-going development. A rolling development.
Your bike Lothar, is reworked where it matters, and completely better than a standard bike. It takes a proper Laverdisti to recongnize that. Not the wannabe jerk, who just got his father to pay him some money, and the cafe latté friends told him from their hipster beards, that Laverda SFC1000 is rare and must be owned, but for nil or a lot of money. Note: Owned. Not ridden. Oh Uh ah! Never ride it!" It will loose SOOOO much money, so you might as well give it away for free. I know there are some people who say: OH, but it is always a market demand. The market decide. The market this, the market that. I tell them a strict NO! It is never market demand. And contrary to most of those self-made "specialists", I have been working many years with serious amounts of money. I developed the computerized trading system (not alone of course) as a pilot project, later for the World to use. and I made it run. Working 60 hours per week. If it broke down, we lost 1 million usd per minute. Billions per day was traded. As someone else wrote here earlier, it is not a commodity (well said, sir), but a hand built piece of Italian motorcycle history. It should sell for a lot more than what you demand. Period. I find your price very cheap indeed. If some people are too cheap skates to see the value, then maybe forget about it. Go somewhere else and play a little market-economic-wise-guy from Uni, and give ill advice to other people, being a so-called "specialist". If I come to sell mine one day, I will decide. Not cheap, not expensive. I will charge what I think it should cost. To the right owner.
Todays selling price is much less than what the new price represented at the time the bike was originally sold first time.
Personally, I would rather see my Laverda buried with me, than give it away for pennies. That is so absolutely disrespectful to the bike and all the hours spent making it and making it better, as well as keeping it in good shape. Even if it was scrap like. Go get a six-pack of chinese xxxx instead, and instead of changing engine oil, just dump it at the mall or better still, the café, and press out a new chinese xxxx bike from the six-pack boble plastic.
I can almost hear them scream: "Oh, but there is a war in Europe. The russians are coming", petrol is SO expensive, no demand for these bikes, new generations are not interested bla bla bla. So what? It such times, there were always people who bought up interesting machines, collectable pieces, watches, and what not, for pennies, and sold them off far more expensive, later on, after the conflict ended, and new found optimism came about.
YOU are the owner Lothar. YOU are the seller Lothar. YOU Lothar decide when, where and how much. Raise your price. It is too cheap.
Or better still: keep it, enjoy it once in a while. It is NOT too expensive to have there just standing. If my own or the life of my wife depends on my Laverda being exchanged for pennies, then there is a systemic economical problem elsewhere that I need to solve; or maybe fatal illness in which case, I may decide to pass the bike on for pennies and hopefully make someone else happy about it. The last coat does not have any pockets. But this is not your case at all. You do fine, your family is doing fine. And you are not hard pressed to skip it for nil. And clearly you won't.
Raise the price.
Take care Lothar and enjoy it when you can, for it is such a good and beautiful bike. I mean that.
Jacques
ps: and my SFC1000 says hello too, despite being red and gold, ha ha!
It was really really warm to ride it last Friday. Phew.
