My 2001 1100 has an oil weep around the tappet cover, just bad enough to spoil the look of the first couple of fins.
I have a set of gaskets, what's the best put them on dry or some sort of cement on one side?
Thanks
Roy

When you say new gaskets are they the original fibre type or the Valpolini ones? If they're the stock ones they're useless and will leak again.

Flick me your address in a PM and I'll post you a couple of the Valpolini ones. No leaks, last for ever. Least I can do with all the assistance you give.

That's very generous of you Pete
You do realize that I'm in Canada, not just across the Tasman
The ones I have are the grey Part No 976139 from Piaggio Group
Otherwise you could just tell me what to order and I will go on-line and find it

A small parcel sitting in my post box today, sure enough it was the gaskets from Pete
15 weeks, has to be a record.
Thankyou Pete

Fifteen weeks? What was it Orca sea mail followed by Special Moose Delivery! Even with Covid that has to be some sort of a record! Laughing

Pete,

Just a reminder please, what year models are affected by this gasket issue?
Does it include the later engines that came from the factory with roller tappets.

Worry not Mark. The issue of failing rocker cover gaskets was confined to the earlier, two valve, motors.

Why, after decades of no problems at all and seemingly no change to the mating area design between head and rocker cover, the gaskets started getting squeezed out and failing I have no idea? It only seemed to start with the CARC bikes and as a rule tends to occur more often on models with the 'Rounder' profile rocker covers, (Breva, Bellagio, Norge.) although as proven by Roy's bike it's not exclusive to them.

The answer though is very simple. Just get Valpolini gaskets. These won't rip or get squeezed out and last pretty much forever. End of problem.
