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

Took advantage of work winding down and headed out to West Head, great ride, not a soul around. West Head was looking a bit parched though, so sad to see it after a burn

Hi Tom,
will you take your beauty to Europe next year ..?

Cheers

Only visible external sign was the hole next to the dip stick, but when I removed the oil strainer and a gudgeon pin literally fell out
I knew the fuck up fairies had visited.
Took the head off and no 1 cylinder was completely empty, piston had turned to confetti and spread itself around the engine.
 
Polished casings and maybe cams.
The duplex chain still looks in perfect condition, but will be retired too.
 
Broken rod, head off exhaust valve. One caused the other, my money is on the rod.

Someone left the fuel taps on? Hydraulic lock, bent rod, and kaboom sometime down the track?

I would guess that this happened at higher revs ...

majority of conrod failures seem to be at low to mid range revs
though I do have one Series 2 engine here never to be repaired that destroyed itself at 8,500 rpm, has holes in the engine cases at every point of the compass  :o

Not according to the owner/pilot - accelerating gently from 60 to 70mph (110kph) when it went onto two cylinders - but still ran....!! :o

And THAT is the problem.  Instead of shutting down, he allowed the bits to fly around and destroy everything they could reach.

One second of running at 3000rpm means another 50 chances of hitting something with the remains of the conrod.  Coasting with the engine running for 500-odd yards from 60mph means another 30 secs of destruction... wrong in every which way you look at it.

I know the 1000 / Jota is loud and not to detract from the enjoyent of riding of course but the instant you hear a loud bang - hit the kill switch and pull the clutch in.
Hopefully not when overtaking!!!
 
This has fuelled my paranoia...Jota going to Keith as arranged some time ago for new rods commissioned by him.Not inexpensive but nor is a written off engine.
 
It seems to be the general consensus now that all triples are best with replacement rods. The reason for the failures is a mystery, as bikes from all sorts of backgrounds have had failures, not necessarily "thrashed" bikes. I know of triples from Oz that did huge miles ridden very hard without problems.

This is mine (as those on the FB group know already) and yes, I did indeed continue to run it. I had no idea this had happened, of course (or I wouldn't have) but literally, she just appeared to go onto two cylinders. Still running when I parked up on the hard shoulder, I switched off, dismounted to see if I could see what I imagined was a loose plug lead or similar, to see the smallish hole in the crankcase, at which point I thought "oh bother"...  :o

I bow down to those who criticise, and of course I am heartily sorry - as is my bank balance - but I'm not sure what else I could really have done in the circumstances. Does everyone immediately kill their engine when the engine note changes in the outside lane of a very busy motorway and the engine feels like it's running on two?  ::)
