Hi Jo, one day before the beginning of spring and I can see from your photos that you are already very much in love ...
Ciao, Gert

Very cool.

Thanks Gert!

Much appreciated Grant! Have not yet decided about ?the? picture for this year ? but hey ? it?s just first day of spring!
Did another trip today and picked up some missing parts at OCT while at it. The German MOTORRAD magazine once mentioned
OCT to be kind of a ?Mototope? ? means a special habitat for unique 2-wheel species ? which is perfectly true ?
Cheers

Nice pics!
Changed the brake pads front and rear today ( Brembo carbon ceramic) as well as changing the brake and clutch fluids.
Then changed the engine oil and then the fork oil.
Then scrubbed the forks, and frame with some mild Muc-off.
Installed all new braided brake hoses front, to replace the 15 y.o. braided hoses it had.
Kind regards,
jacques

Yup - I'm one of the great procrastinators. With temps finally above freezing here in Calgary I am suddenly motivated to get it fixed.henrywillms said:

I am inclined to doubt it. A knackered o-ring won't allow oil to spew out, you've got almost 2cm of head gasket outboard of the stud hole to hold back any oil.
Check liner location in the barrel. If there is any protrusion, no matter how small, a new gasket and o-rings is not going to fix it. A small recess, 0.1-0.2mm, is required for the gasket flame ring to set itself and to afford the remaining gasket enough pressure to be oil-tight. The o-rings are only a precaution against the engine sucking oil past the flame ring where it is pinched to allow the studs to pass (a crap design that works quite OK if assembled properly, this applies to all triples
). You do of course need a correctly made gasket, the flame ring MUST be a tad thicker (0.2-0.3mm) than the gasket itself.If the liner protrudes, all pressure is on the flame ring and very little on the surrounding gasket area, oil will quickly find a way out.
Alternatively, 1200s allow the fitment of a completely flat gasket IF the barrel top surface is completely flat, ie, the liners flush with the sealing surface.
Liner protrusion looks like the liner creeping out of the barrel, but is actually caused by the alloy of the barrel shrinking after innumerous heat-cycles. In this case, the liners can be removed and the flange altered to suit (I machine the underside of the flange). The liner flange can also be machined when in situ, a delicate and tricky OP at the best of times, but required if the fitted pistons are to be re-used. It is not advisable to re-fit used pistons if the liners have been removed/replaced.
BTW, Weeping Head Syndrome is not only a Laverda problem. Many hard-used CB750 or Z900 show exactly the same symptoms, caused by the same shortcomings.

Thanks Piet - I will definitely check for correct recess for the gasket flame ring. I seem to recall that the recess was fine when the motor was assembled last year, but will double check. Have to put the diagnostics for this on hold for a couple of weeks. Just got invited to a week of dirt biking in Moab - need to hustle now to get my Beta sorted for a spring trip.

Gets a little busy in the summer - camping cars, Belgians, Dutch etc :-X. But had it pretty much to myself at this time of year.
