Oil and grease:
to choose the engine oil?
A Laverda engine doesn't need a very sophisticated lube system because of numerous ball (or roller) bearings. Considering that tolerances are not very high, that there is not a
good oil filter (just a strainer), and that there is an oil cooler on 1000 (and last SFCs) which can be empty of oil after a long stop, oil should be of rather high viscosity, not synthetic
type but of good quality.
15W50 API SG of a high mineral or semi-synthetic oil should be the best way to lube a Laverda engine, Elf Competition, Motul 3100 or Castrol Grand Prix for instance.
Remember that the oil pump tolerances, as about the entire lube system concept, shouldn't tolerate full synthetic low viscosity oils, like 5W50. In addition, these synthetic oils contains
a lot of cleaning additives, which are dangerous for our old engines,often clogged, especially into the crankpins.
Lube system of triples
I don't see a big difference between oil or graphite (dry) in term of efficiency. However, I think that oil is a better choice because it avoids water under rain and it can lube the
pivot point. Another possibility is to use some tallow product, available in spray in nautical shops: This product has very good qualities and avoid any water along the cable.

Simply a good lithium grease.
