What did you do to or for or with your Laverda today?
- Thread starter CLEMTOG
- Start date
We got home Wednesday afternoon.
We woke up to pouring rain in our campsite in Pierrefonds where we'd stopped two nights to visit the extravagant castle.
Setting off in the pouring rain is always disagreeable, even more so if you need to put a fully charged battery in your bike under the rain.
Only 170 km until home on this last leg, due North, and luckily, the rain stopped after 30 km or so. I was particularly pleased as I was riding without lights, Corinne leading.
Through the Compiègne forest where the armistice was signed in 1918, and then through the plains of the Aisne, the Somme, the Pas-de-Calais and the Nord fertilised by the blood of so many men in that bloody war.
We arrived home in the beginning of the afternoon.
Yesterday, Thursday, I took the old dynamo belt off, it was very loose and put a new one on. Not really very tight nonetheless. The photo is the old one.
I started the bike up, and it still wasn't charging, so the problem was either dynamo or regulator. I have spares for both.
Today, I put a voltmeter on the dynamo. 3 volts at 3000 revs. There's the culprit. I’ve taken the dynamo off and will open it in the coming days to see if a clean of the collector and possibly new brushes cures the problem. If not, it will go off to be repaired and I'll put another on the SF2.
We covered 2300 km in two weeks, not a record but this was a holiday. Add that to the 2500 km ride to the Amicale 750 Laverda meeting in the Alps, and 500 km in the hands of one of my sons mid May and that's 5300 km covered for the SF2 in just over two months. Apart from the dynamo, not the slightest problem. About 750 to 1000 cc of oil consumed. Time for a rest now. Another 3000 km planned in September with friends on British bikes which I'd like to do on the S if the clutch is sorted. If not, out with the SF2 again.

So put in the Champions yesterday, can't really define the feeling but it feels a bit more eager, though that could be entirely the imaginary effect of putting something new and shiny in.For what's it worth with modern fuels, here's the B10ES after a ~100km ride with E5 (98 octane) fuel, half of it motorways at ~100km/h as per the pretty accurate Sigma, if it were op to Smiths I'd be at ~120km/hLast 15km or so slow driving. (traffic, villages, etc).
Took it for a ride, 75km or so. Here's how they look, same tank of fuel but a bit less touristy riding overtaking slow German tourists, campers, etc. Can you still rely somewhat on the colours with E5 fuel?
Currently at about 750km total I put on, getting to know it more and more and liking it even more and more -neither the 750 nor me are racy type of riders but it corners and handles much nicer than the R90S I've owned for so long....
Oil level did drop a tiny bit but nothing bad, starts on the button, but will need new seat foam/repairs this winter.

None of my 750s would even vaguely run with B10s.
I use B8s in all, otherwise the choke kills the plugs and I've gone down 5 to 10 points poorer on the idle jets of all my bikes, SFC included. The SFC would kill the plugs after two starts and 10km. Now, all's well.
As for fuel, the SF2 was really buzzing on 95 E10 on our recent trip. It's likely alcoholic.

Funny thing, mine has run on B10s since wayy back when it still had the sidecar (pre 1992 or so?). Started right up on the button, no fouling or ill behaviour ever since I got it and knowing my father he would not accept that behaviour and fix it if it was needed. I've changed them for the N2C's because nobody seems to have B10ES or can order them & I don't want to rely on something exotic that should be available and simple -enough exotic stuff on Laverda's as it is already?
My father confirmed my feeling the carburettors are very worn, it runs some non-standard settings to compensate as he (at the time) was unable to find good VHBs and Keihin or Mikuni stuff from his parts box would not work or fit. As I wrote earlier it's a GT but has a much higher compression ratio that makes me a bit hesitant about E10 -my BMW has roughly the same CR and does not like it much when it is warm outside.
However if your SF2 likes it, I might give it a try.
Carburettors are still on my to-do list but I fear the price tag of a decent set of VHB's... There are used ones out there but whether they are good or not? It runs nice as it is but wear will of course not go away by magic. Found some threads about conversions here so more reading to do, it should last until winter

To run so well on such cold plugs it would be interesting to do an accurate CR check on your bike. Use a burette to fill a cylinder (bike leaned over a little, fill to halfway up the plug hole) at accurate TDC with an oil-kero mix. Add that figure to swept volume and divide by that figure.
I think I found why the dynamo wasn't producing volts.
The brush isn't worn, it's just not free to move because of carbon dust.
While I'm at it, I've ordered some new ones which I should receive by the end of the week and off we go again.

Just arrived at the farm I’m staying at about 15 minutes up the road from Willersey, ready for tomorrow. Lovely smooth ride on the ‘now run in’ GT. Roughly 100 miles from home.
Only stopped once, in Woodstock, very pretty place. Had one of those nice random chats about the Laverda and other things with an elderly gentleman who was out for a walk.
Have fitted Trip Machine saddlebags for the first time. Have to say I’m very pleased with them. Easily enough room for clothes, tools, bits and pieces, even a bottle of wine.

You should have painted it orange. You're going to stand out like a ripe bunion on a nose.

The last time I got my 3c painter I didn't want it Orange, so I went red, as red as it could be. I tried to match the power coating colour I used called Signal Red. As vivade a red as i could find.Heading home with the bits in the car i asked the bloke with me if it was as red as the car in front. His answer was NO, its more Orange than that, this continued all the way home with the same answers. After fitting all the body work, my choice of RED somehow ended up Orangy red, or simply more orange then red. A reddy orange.

A blood orange. A good one is delicious.

That is the hottest "cold" plug i have ever seen, something is not correct there. j

Surviving members who turned out at Willersey? (although some some look as though they are surviving slightly better than others..)

At the 7. Hill Climb Revival in Bad Muehllacken/Upper Austria I did only the first run, because of heavy rain in the second. 40 race bikes and 140 race cars - so more a car than a bike event. But we had 5 Laverdas in the run: 500, 500 Barcelona Replica, 750 SFC-E, 1000 3CL and a 750SF sidecar. Every participant got a nice trophy. Ciao, Gert

Awesome, Gert! So good to hear about an SFC being thrashed - and i bet it loved it!
