Who knows Thomas?

You need luck in life.
I was very lucky all the times in my life I've ridden after having taken all kinds of substances.
I remember once at night, after a lot of alcohol, looking for the campsite on the SFC, on small unlit country roads. The people in the campsite could hear me riding around. I finally found the campsite just before giving up, putting the bike on the stand by the side of the road and sleeping in a field.
I was also lucky riding back to the campsite in Locarno at night with no lights on the SFC. They decided to quit after the restaurant. (don't go to the restaurant in Locarno, they only like people with money, not those with not much to spend)
My last time out at Francorchamps on the SFC, I must have been very lucky indeed, because not only did the primary chain resist numerous downshifts, but I still had enough brakes with only one front disc. The other one was full of oil from a leaking fork seal.
And that primary resisted another couple of track outings after that.
The front wheel needed 600°C to fail. Otherwise it was alright.

I of course didn't needed to change the rear magnesium hub on my SFC because it has cast wheels.

I was however also very lucky running my 600 TT2 on the original Campagnolo magnesium wheels. Luckily, the bastards who tried to burn it didn't know about Campagnolo magnesium wheels.

I forget nothing.

And I'm now nearly 70 and hope to keep on riding for as long as possible, and being lucky.

Who supplied your primary chain?

The primary chain was a "Regina Extra" originally bought at the Laverda factory. I used to go to the Laverda factory several times a year. Either to buy (cheap) parts or just to visit, when I went to Turkey, Greece, Sicila, ... with the Laverda. They were thrilled, because we drove packed full such long distances with there Laverda.

We saw new developments/models, or we were invited to lunch in the canteen. It was a very beautiful time.

My 74 SFC is running 2 single row primaries, I think I'll be fitting a duplex when I recommission it for use again. This year I'm hoping to do a couple of races with it at the recently extended Collie motoplex. Would love to race the Motodd but don't think it will comply with any of the classes available. I don't plan on registering the SFC for the road so a track is the only way I can ride it legally. My SFC has done 29000 miles of which 27000 were on the original triplex. It's had a good thrashing for most of them miles too.

nice
 
Hi Thomas, have you found a source for new SFC or replica sprocket holders (and hub?)? For lack of finding that, about 1998 I switched to a Suzuki GS750 spoked hub and cush drive on my '74-SFC race bike because all but two of the vanes on the original sprocket carrier had broken and I could not find anyone who would try to repair it. I'd like to return to the original Laverda hub and sprocket holder if that's possible.

I think MotoOfficina makes billet replicas.

They do.
But I should think that the usual Italian suspects also can supply the parts.
Andy Wagner at Laverda Paradies lists the hub and disc.
I'm sure Wolfgang Haerter might have some.

Bloody thin crown on that buggered piston too! Nice bit of weight saving on the primary cover - and a bit off the end of the crank too, I'm guessing!

... the roof of the pistons was apparently milled off by the previous owner - don't ask me why! The pistons broke at very high revs on the racetrack.

Well that's just incredible stupidity, I'd say! If you want to lower the compression that certainly ain't the way to do it! 🙀
 
I lowered the compression ration using two base gaskets and 8.9:1 flat top Mondials (1200) but it only worked because both the head and the block had been decked, the head, perhaps one time too many, its the cam chain length that was the problem, the head failed (bad ignition) and a replacement was thicker, so I couldnt re use my low comp set up. it was lovely when it was together though, but top speed dropped a tad, maybe by 20MPH, which meant it would only do 147, but hey ho, life goes on.

what I am trying to say is that its not that easy to lower the comp below the 8.9:1 pistons, which are not available anyway. (every one wants high comp)
