Club Laverda NSW Tour de Tasmania 2023

Tumbarumba last night, last day today. 6500rpm in 4th wot, old triple pumped half a litre of oil out.....

Blown head gasket, looks like I'm walking home.

Bloody hell Marty,

looks like it has incontinence. But for its age at WOT, not too bad.
Only a small problem tho, only down the rhs of the bike, lhs still looks ok ?
 
Oil from where, Marty? A hole in the cases or the breather - big $ difference! My SF1 did a breather flow south of Darwin - VERY worn rings and bores.
 
Tested to destruction, you got your money's worth. I hear there is a new design of head gasket that deletes the O rings.
 
Marmalade the recalcitrant 3C is back in the shed. Thanks to Chris Kay and his huge Tonka truck setup. Job well done. Sorry about all the oil in your trailer.....

Oh, and I don't think there was any reaching, none that I felt anyway
 
Cam cover off, stud at the back of #3 piston has let go, no tension at all. All the other studs still at correct tension. Compression gases have gone straight into the cam chain tunnel, pressurising the crankcase. Oil pressure would not have been effected, no other damage. Engine out, timeserts to the cases. Wish me luck.
 
One stud, which is really weird. How does one stud pull out?

Who knows? Maybe that thread was always a bit marginal, and on that last WOT run it had finally had enough and let go. You gotta expect these things with old bikes.

Good to catch up in Tassie. Hats off to you old farts for travelling all that way on clunky old Laverdas. I reckon that kind of distance on my Jota would kill me. That's why I bought the Multistrada with its fancy electronically adjustable suspension. It's way more comfortable to ride, but I find all the computer wizardry a bit frightening. If that gear goes tits-up there's no fixing it on the side of the road.
