Damn, that’s massive. Any ideas what caused it?
I'm thinking the con rod let go, and knocked the head off no 1 exhaust valve. The valve head was found in the sump and looks relatively undamaged, suggesting the main damage was done before it was broken off the valve stem.

Slingers were full of crap.

God ,that's a mess.......
i bet that sounded like the silverware drawer in the kitchen being dumped on the ground.
I turned the cases upside down to access the nuts on the underside and the sound was like if you put silverware in the tumble dryer, and big chunks of metal were dropping out of the mouth of the cases.
The engine is a write off. A new bike has already been purchased, and the bodywork will be transferred to this bike.
Crank work continues on 007. Ready for rebuilding after the slingers were cleaned out and new small end bushes fitted and reamed.

The crankcases have now safely arrived so they will be laser weld repaired. I also finally sourced a damaged 1000 cylinder block so it will have the liners removed, bored out to 1200 and then re-linered for standard pistons when funds allow.
We you able to salvage the transmission?
Don't know yet. Will check when I have more time.
Visually looks ok except the clutch drum is frozen on to the mainshaft.
Nice job Grant and you came up on the SA media when you found a crated as new bike as I remember - dark green?
Is this of interest; ex speed cop bike?

The TS Mirage as in the link is one of the least desirable Laverda triples with regard to market appeal. Prices reflect this.
The only triple with less appeal is the 30th Anniversary special.

I didn't find the crated 3C, just posted about it. It was found by a friend of a friend, in Belgium I recall, when an old guy passed away and the family found it. I think the bike is now back in Italy. The buyer uncrated it and is using it as the manufacturer intended. Probably killed the value but to me it's good to see bikes being used instead of stuck in glass cases in someone's house.
Why's that? Tbh I really like the look of that Lavera (and being less desirable might also mean that I can afford one as a "youngster")
I'm guessing because Laverda owners did not like blacked out (previously polished) cases, gold painted frame, gold coloured bolt heads and the childishly drawn '30th' on the tank.
Today is my 7th straight day bedbound with man flu.
At least it has allowed me to plan next steps (within my financial straits).
Currently I'm waiting on the crank to be rebuilt and the crank cases to be weld repaired and returned to me.
I have also sourced a set of cylinders for this project now but can't do anything with them (they need liners removed, block bored out to 1200 and re-linered plus new pistons) until cash flow improves.
I need to attack the donor bike to liberate the wheels, forks and yokes and will start this work in the coming week.
That will allow me to get the wheels and yokes stripped and painted and to see how much work the forks need.
I also need to order a new ignition/alternator system for it, another major expense.
But after that it's just easy stuff, mainly the braking system as I have most other parts covered, including brand new discs.
Time to get to work on the donor bike. Here it is in all it's glory, as-purchased.

Got a bit done today.
Dug out a pair of wheels, forks and yokes to fit to the donor bike and allow me to remove the ones on it as they are what I need for 007.
I can now strip these parts down for restoration.
Man, the more I look at the donor bike the more messed up it becomes. Someone really did a number on this poor bike.

The long term plan for the donor bike is to resurrect it once 007 is completed, but it will be a restomod rather than a full concours restoration. I have wider wheels, bigger discs and 4 pot calipers left over that can be used. But that is a long way off.
For now I'll rob it of any parts I need for 007.
Was the square tube added to lift the tank for carb clearance?
Yes, and wrapped in an old inner tube. Who the hell knows what the tank is originally from, but it sure isn't a Laverda.
The level of bodgery on this bike is approaching genius level.
Poor bike, I had no option but to try to rescue it.
Finally removed the wheels, Ceriani forks and yokes from the donor bike.

I had some Marzocchi forks and yokes and some odd wheels with tyres fitted so I rebuilt the donor with them, just so it was still able to be rolled around the workshop.
2019-01-06 12.13.52 by Grant Duguid, on Flickr
Now I can disassemble the wheels and yokes for painting, and I think I'll get the fork stanchions re-hard chromed.
All this will allow 007 to become a rolling chassis, making it easier to move around and gets it down off the work table.
Stretch goal is to have the bike finished ahead of the Scottish bike show first weekend in March but that is a big ask considering I still need a lot of engineering work on the engine parts first.
Worst case is I take it as a work-in-progress rolling chassis to demonstrate the steps involved in a restoration.
Started stripping down the yokes and wheels in preparation for repainting.
All going well until I found this.

2 of the 6 bolts holding on the rear disc had sheared off. Looks like a lame attempt to drill them out had been made.
When I removed the disc carrier there is around quarter of an inch sticking proud so I'll get a couple of nuts welded on and get them out.
This poor little bike has been used and abused to within an inch of it's life.
Looks like at least 4 layers of paint will have to be removed (silver, yellow, blue and then black).
Got all the parts stripped down (bearings knocked out etc) for blasting and painting.
Should get the 2 broken studs out on Friday.
I ordered new wheel bearings and tubes/tyres too.
