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

I've been fixing the little details that make a bike feel good on my 3C. I've done 2km around the indoor car park. I hope the 550 neighbours appreciate my efforts. Sounds great but to get a reliable tickover I have the carb screws 2+ turns out. Never had that before.
 
After many years of "one day I'll take all these parts to be properly cleaned" procrastination and an ever growing pile of 750 twin parts in the corner, my neighbor and I installed a joint partnership vapor hone machine and I got started on the first batch of Laverda bits - yeah hah!!!!!
My son at work, before and after on head and barrel:

Lots more parts to work on then no more excuses, time to start reassembly!
 
Put a bunch of brand-new Voxbell horns on the 74 triple. Brand-new Voxbells not working 💩 I have had used ones go wrong (you can hear them click but no real sound) - does that also happen to new ones, after extended shelf-time?

The restorer had replaced the original working horns with replicas. Just like he replaced the original seat, the original front calipers, all Laverda logo bolts etc. At least he didn't upgrade the 200mm lamp with a 180mm. He also distanced out one front caliper with washers without then using a longer mounting bolt. Also found two engine mounting bolts that were a bit on the shortish side. I shudder thinking about the insides of the engine....

I am glad my 73 triple is now at OCT, but the engine on that bike was also done by same guy as the 74....

But those would have the same dimensions otherwise, right? Why not space the wheel correctly in the first place?
I have just fitted some single bleed nipple calipers to Ceriani forks and have had to use spacers. There are some minor dimensional differences, for instance the little peg that sits on top of the pads is a different width. They look the same but they aren't, Ducatipaddy can give you chapter and verse on it.

Well the way I see it and I could be wrong, the original Cerrani threaded calipers would have a machined/cast face on the out sidfe of the caliper to mount on the inside of the fork mounts. The Marzo units mounting face is on the inside of the caliper to mount on the outside of the Marzo fork mount so the opposite. As the back face has no relationship with the mounting face there probably requires a shim to centre it. One would hope that the back face of the Marzo designed caliper is cast/machined square as this is now the mounting face, if you get what I mean.
 
Rob is correct.

The Ceriani and Marzocchi types are not identical in regard to the mounting lugs. The machined faces are opposite, the un-machined faces not necessarily square or parallel to one another. Fitting the calipers on the un-machined sides always creates a bunch of problems that require quite some "creativity" to solve.

and PO8's fitted to BMW twins have a totally different offset,loads differnt, could even be 8mm or so, I got as far as rebuildimng and re-painting one for the rear of TOG, only to find out, damn and blast it.

Just got back from a slightly longer-than-usual ride, in glorious weather, and feel like I could do it all again.
Why...?
Cos I just fitted a PS13 clutch master (y)

Not very pretty, and the dash doesn’t fit with it, but so much easier.
(If anyone knows of a nicer looking option, let me know)
