2010 v8 rollerised GRiSO with 17k miles,
Noticed this the other day, only heard when its warmed up.
I've read all about noisy GRiSO's but still not too happy with this...

No idea what oils were used by previous owner, And shes probably due a change.
Any thoughts?

I've heard that rattle (or very similar) in several video's of modern guzzi's. For example:

Can't really help you identifying the cause, as my bike doesn't have it and never has. Just to state the obvious, did you check the valve clearances?

I'll have to try and listen to it on something better than my pad of eyes, the sound quality is shit.

Is it a sort of 'Dack-Dack-Dack' or 'Bonk-Bonk-Bonk' noise? If so I'd be pulling therod caps for a looksee. There again it could just be rattly chains.

The GRiSO one in Timothy's post definitely has a fucked bottom end.

Sounds like valvetrain noise, but hard to say with all the other noises going on. Perhaps try pulling the clutch lever in for a bit which eliminates the dry clutch rattle noises. Usually makes it much easier to identify noisy tappets etc when the clutch noise is removed from the equation.

Screw driver in the ear can sometimes help locate area of noise creation.

That ones not good Rolling Eyes

If it's had jap bike oil put in it , too thin , change it to the correct 10w60 full synthetic spec, it will quiet it a little

Thanks for replies lads. Out today for a spin and that rattle was no where to be heard. Got well warmed too. Will check valves and do a service with correct oil (got a service kit minus oil from previous owner) now. .. to start reading oil threads!!
