Pfft, and I thought plane spotters were a tad eclepic.
But frame number stamp rubbing? That takes it to a whole new level.

The Google I knew would have corrected you, before the mishap happened

Blimey. I bet the dark winter evenings just fly past !
Well Yes, Yes I am. Cheers Jim from the Kootenays!
I guess first time for everything. This SF2 was original purchased by Slater's accountant after sitting in its packing crate for a few years.
Balance Box and pipes are sitting in my garage loft. Do owners still ride their Laverda with the Boxes?
Oh I guess if you avoid doing that leaning thing in a curvy road

Gentlemen, let's play nicely!
I have two similarly stamped "Jan '74" headstock plates with the J stamp reversed - don't assume it's bogus.

Hi Wes 1,
please could you go in your garage loft and ask one of the pipes sitting around, what happend with their clamps near the cylinder hat?
Normaly you have a gap of about 5 mm to the cylinder.
Let me guess - we have here „chopped“ clamps? ;-)
Thomas aus LAU
Thanks for the nice comment, much appreciated.
Hey Thomas, I will take a look tomorrow. Thanks for the interest. Cheers.

Hi Wes
As you've discovered, there are eagle-eyed punters on here that will pick up on everything that deviates from orig, so the term 'pristin' will be taken very literally!
Looks to me like you have nicely curved custom headers, so I'm guessing the section that fits into the cylinder head is different from a factory header?

and at the risk of stating the obvious
Please consider that J does not exist in the modern post-Mussolini Italian 21 letter alphabet - Jota as a word would never have come from Italy, just don't go there with Juventus!
So it's quite reasonable that the J stamp in January in English was a strange thing to a young Italian factory worker accustomed to Gennaio, if somebody gave him/her a reversed stamp and told him/her to go bash it into all those little alumin(i)um sheets for them 'Merrrricans, what was (s)he to do?

The exhaust collector is indeed a big limitation if you like to get into it in the curves, it reduces your margin for error quite a bit. Many people are happy to have it though - but not me. It is also very efficient at making the bike very quiet without affecting performance.Balance Box and pipes are sitting in my garage loft. Do owners still ride their Laverda with the Boxes?
Would have been square type originally.Fuel Taps?OMG What about the Fuel Taps??????????

Hey Thomas, I compared the Balance Box headers with the ones that are on now. I didn't feel like taking a non balance header off to measure the length of the flange that inserts into the exhust port but it appears to be a bit longer than the balance box header. If so that would account for the extra spacing between the cylinder and the header coupler.
I have the balance box on the SF2 which was my ride to work bike nearly until I retired. It's very noisy without.Do owners still ride their Laverda with the Boxes?
My short experience without it ended because the exhaust system not being supported, it grinds away at the copper exhaust gaskets leading to having to tighten the collars to the head every day, or every couple of hours.
If you devise a means of securing the exhaust rigidly to the chassis or engine, it then just becomes very noisy.
More so than the early bikes with the nearly straight through system.

I find that really odd, Paul, cos I ran my SF1 for decades and several hundred thousand km with rigidly mounted Ducati Contis, including race seasons and thousands of km on rugged Australian outback unsealed roads, corrugated to buggery and loaded with bulldust) - and never once had to retighten my headers at the flange. It's the system you can see part of in my avatar.

Can't have much exhaust stud left protruding from the flange on which to fit the brass M8s. Would be a good idea to rectify it by making a perpendicular cut with a cutoff angle grinding disc in a jig, back to the right size.

But of course, the rear mounts might no longer align?

Unless you also take the same amount off the rear of the header pipe.
My SF had to do a certified noise test, all sorts of stuff including full throttle 5000rpm ride-by, and with Conti replicas it passed within the limits. It is nowhere near as loud as either the American noise machines nor the hoards of kids on their 125s with Akrapovics, which seem to be the main offenders around here.
