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

You can also just clamp large dia foam socks right over the bellmouths ...

Ha ha, you just reminded me of a funny story. When I was a teenager, I cut up one of my mum's stockings to use as mesh filters over open bellmouths on a Yamaha 250 2-stroke twin I had at the time. I stretched them over the bellmouths and used thick rubber bands to keep them in place.  Started the bike up, all good so far ...  Gave it a handful of throttle and both stocking filters disappeared. They got sucked out from under the rubber bands and disappeared into the engine. Being nylon I assume they just got burnt in the combustion chambers and the ash spat out into the exhaust. The engine didn't miss a beat.

Tippie tried the stocking over the bellmouth on his 350 Mk3 Ducati and it wouldn't breathe  above about 2,000rpm!
 
Any kind of mesh on a bellmouth fucks up the air flow. Those grey plastic dellorto trumpets with the convex expanded mesh strainer in them, beloved of Bevel Ducati SS owners, are particularly awful. They're more restrictive than a normal air filter. Chuck the mesh strainer away and you get a few more ponies out of the engine.
 
Took my 3C for a ride on a clear, cold and sunny day.   
This after ten days of weather mayhem in the Cape province - ferocious storms, uprooted trees, flying roof sections, and wind driven fires (over 500 dwellings burnt down in the Southern Cape).

This is getting silly, aside from being mathematically meaningless. I mean, multiple operators are bad enough, but raising them to a power? As something of a mathematician, I'm deeply disappointed. Go and stand in the naughty corner.

They are re-manufacturing the Phantom tread - on the principal of the 'Rivet in me'

(somebody had to do it ;))
 
Thanks gents.    Pleased to see that you all have such fine taste in motorcycles!

Maurice, no not a Pirelli Phantom, although I wish it was.  Had some fine hooning moments on those tires.  The ones on the 3C are Bridgestone Spitfire S11?s.    Also have them on the Jota.  They work pretty well overall.  Unfortunately, in my part of the world there?s not too much choice in tires for classic bikes.
