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

Are the bearings showing any sign of wear? I've never worn one out.

I haven?t looked yet and as far as I can tell there are no irregular rattles etc from them, however I understood it was good practice to change them at the same time as a primary chain replacement while you have the casing off?
The last chain I replaced on another series 1 Jota the crankshaft outrigger bearing was in pieces,so definitely worth checking.

Not really.

Every time the bearings are pulled from the primary cover, the interference fit will suffer, even if you are careful/fortunate enough not to remove any metal in the process.

Inspect the crank for run-out and the inner race for damage.  If run-out is excessive, something should be done about it, chances are you will then also find signs of damage on the race.  If the inner race is found to be damaged, the bearing must be replaced as well.  I find a lot of loose inner races, often caused by excessive run-out and/or incorrect fitment.  Be aware the locating punchings can distort a freshly fitted inner race!  Not unusual to find damge corresponding to the punchmarks on the end of the crank.  A race that has been loose for any length of time will wear the crank journal, often making a custom race necessary.

The mainshaft outrigger bearing rarely has any issues, you'll have to manage to bend the shaft for that! :D

Leaded petrol comprises of a additive that's added as the road tanker is loaded that's why it's expensive. There's no leaded units on refineried any more but plenty of free lead from the deep Wells.

Interesting, when in Europe I noticed the fuel smelt, almost pungent, totally different to Australia ......... I wonder what that's all about?

It peels off wonderfully from the insides, Clem  :D.  Then the tyres won't seal ... >:D

An innocent owner might have hoped Marchesini would have been able to do better  :-X.  Me, I dunno ..
