What did you do to or for or with your Laverda today?

[sfcpiet]

Suppose they had used 1200 Mondials, in which case the pockets were not suitable for the elettronica’s bigger valves and different valve angle.

Marnix

The pistons of the 1200 have 3mm less compression height compared to the stock 750 pistons.

I have 1200 pistons in my long-stroke GTL, and yes, the valve pockets needed to be modified, even for the small valve 750 head.

To make them work in a 750, either a longer stroke or longer conrods are needed.

Exactly, that’s why they would fit an Elettronica, with altered pockets. Not that I would recommend it..

Flat top (from very early 750) pistons, if can find them, would hit the cylinder head even before reaching TDC..

Bugger me, that's a 'small world' coincidenence Piet. I took my Yam MT07 for an MOT this very day, and, whilst waiting, read Classic Bike magazine with Bob Dixon's report of the 75th, and there you are talking about exactly the same thing! Best wishes from sunny England chap.

Small world indeed, Paul!

Wouldn't find any classic bike mags in TÜV waiting rooms here...

Didn't occur to me it was that much difference, just checked.

Elettronica Asso piston vs 8000 SFC Mondial.

Took my Viking chum’s Formula 500 for its Manx vehicle inspection today. Apart from a few minor advisories it was assessed as fit for riding on the road, not that it is the immediate intention. The main reason was so I can get a vehicle registration document for the bike, which will make it a lot easier when it gets transported to Norway, probably next year.

Is that the Formula formerly owned/raced by Leif Israelsson?

No, it’s a different one. The series two F500 replica you mention, and now owned by Rune, is still in Norway. The series one bike, that was subject to the vehicle inspection, was one of a pair of F500s (1882 & 1883) imported by Slater’s in 1978. 1882 is incidentally owned by me. 1883 was re-exported by Slater’s to South Africa a short time later. It was sold on, unregistered, to a chap in SA and eventually ended up, a few years ago, in the hands of another South African who had homes in both the UK and IOM. He reimported the bike back into the UK, and then shipped it onto the IOM, which is when I got involved. I negotiated the purchase for Rune when the owner decided to sell it.
Incidentally, Leif also owns a series one F500 and it’s only one number away from Rune’s bike. We were wondering, when we discovered this interesting little fact, at the ASI Motor Show in May, who owns 1884. (Is it still in Germany as listed on the Laverdamania registry?)

Jotas in dry dock at the moment for maintenance,trying yet another set of front brake pads due to "Grabbing brakes" at low speed which is uncomfortable to live with..This time I have gone with Ferodo Platinum pads (non sintered) and we will see how they perform and report back.

Unfortunately the left hand fork seal has also decided to give up the ghost so time for a set of new seals and some fresh oil.
Currently waiting on spares.

The pinch bolts are not quite parallel, please rectify.

Jesus, you should see my garage.

As bad as it gets!! The shame, the shame!!

Don’t feel too bad, I can probably match that just now.

Once I start tripping over shit it gets put away, and then important shit disapears for months on end. Recently, I finally found my Countersink Bit, missing for a couple of years. It was just were I thought it was but hidden under other important shit. Best recent purchase, a rechargeable camping head torch, handy in a shed with no permanent lighting, says the bloke who cannot find anything.

I'm not good with horizontal surfaces either - after a short time, I can't fit anything on them anymore …

 

[Haggis]

I'm currently dismantling and packing my garage for a house move. Jeez, what a lot of stuff (shit) Decisions - what to bin versus what to keep - agony! The new place can't take it all.
