Making progress on my '74 3C

My 74 3C tasks are proceeding apace. I have cleaned the fuel tank, rebuilt the carbs with the worn parts replaced, and cleaned and bagged all the bits I'm fixing. The fork internals (like the carbs) are very good, it's just clean, polish, and replace rubber seals/shrouds/O-rings. Brakes are next, waiting on kits.

I've done the wheels, and will mount and balance the tires in the coming days. New instrument faces are on the way from Germany. The whole upper area of instruments, headlight mounts/fork shrouds, and related bits should look new, as I am replacing / re-chroming stuff as needed. Oh, I took the springs off the original (crap) Ceriani shocks & refurbished them externally. They are operational, but yeah, no compression damping at all. I'll replace them with something good down the line.

I'm down to only a couple of small choices, such as: What grips and what mirrors shall I choose? I have some original chrome Napoleon bar-ends, maybe use those.

I'm on to polishing. I cheat a bit on the wheels, I must confess. The spokes looked tired, I sand them back and apply Seymour stainless paint on them with a brush. Not gonna win any concours, but it comes out pretty good. I have laced many wheels it's just the cost for new spokes at this time, more than the effort.

Looks great-clearly not your first rodeo! Can't wait to see the finished product-
 
I have perused Bevel Heaven's site, but ultimately bought in bulk from DAM, and escaped any tariff on my order. With no VAT and no sales tax, the order was quite reasonable. Not my typical Suzuki cheap, but hey.

There is also an eBay seller (valtermotousa) that beat everyone on genuine Dell'Orto stuff, plus some other bits like tank rubber strap, so I got a bunch from him. On shocks, I see these Bitubo shocks, they would seem to fit, and the price is good - the full chrome ones are a couple of hundred more from every other seller. Still researching. On my '79 Suzuki GS1000 I had some vintage Fox shocks that I rebuilt, they were the best twin shocks I've ever used. I'd love to find some to fit the Laverda but that's probably a pipe-dream.

On MC's, I will see how things go. I upgraded my '66 Norton N15CS with a '73 Commando disc setup, and downsized the MC bore, referencing this chart. The original was a huge affair with too large of a bore. Turned out a Yamaha scooter Nissin MC fit the bill nicely, got off eBay for $15. It is fantastic, great feel and is gives more power than the tire's grip can keep up with at any speed I've tried. And that's from a single disc.

Hi Paul - Today I received the kits for the calipers and PS15 master cylinder, and they are good to go... except for the MC. There's a dust boot that is not included in the kit. It's the very first rubber boot that slips over the piston, as is typical on MCs. Do you know what that PN / availability may be? It is something like this. Mine was disintegrated.

Next question, how about that rubber banjo cover? Yours looks minty fresh. Do you have PN or info on where to source?

Lastly, not a question, but just FYI for anyone looking - the internal reservoir bellows for the MC is available individually for $5.50 USD (plus about $14 shipping to CA) here. It was a challenge to find, but I ferreted it out, and it's on the way. Measurement seems right. I hope I'm not mistaken.

There's no dust boot on the piston on those mc's.
There's a file posted by Lothar some years ago somewhere on this forum, it's most useful.
As for the banjo cover, I had it in my pile of bits but I should think that it's readily available from any supplier of Brembo or hydraulic kit.
