Just got a Griso and worried - please hep!

[Jaydoubleyou]

Hi folks,
I am looking for some advice.
After years of lusting after Guzzis, and months of looking, I got an 06 Griso 1100 today.
It is an immaculate 2 owner bike with full service history and 7k on the clock.
I had a whale of a time on it today, with a mile wide smile.
When I got home I noticed a rattle/knock from the bottom end, seemingly the transmission. This goes off when the clutch is pulled in, and was definitely not noticeable when the engine was cold.
Should I be worried and get it back to the dealer as soon as, or is this normal.
Any advice would be greatly appreciated.
Cheers,
Jeff

Almost certainly it's the lobes of the face cam shock absorber on the input shaft knocking together. Early Brevas and Grisos had an issue with the Bellville washer spring pack collapsing allowing this to happen. It apparently causes no damage and the fix requires gearbox removal and disassembly.

Would you suggest getting it looked at, or is it safe to just ignore it?

[Vasco DG]

I'd certainly suggest getting it looked at/listened to by someone familiar with the issue.

Couldn't this just be normal dry clutch chatter?

Note he says it goes away when the clutch is pulled in. This suggests face cam rather than clutch.

Ah I red it the other way around. Disregard.

unrelated issue, yet have it checked: the three fasteners for the Grimeca clutch slave (on the back of the trans facing the rear shock) were typically shoulder headed hex bolts...yet the holes in the slave are countersunk for flathead screws. As a result, the hex bolts can tend to loosen or even fal out. the result is that the clutch hydraulic fluid drains out, thereafter causing the transfer dowel to seize in the case. In short, it's a quick check- yet a potentially ugly repair. If the rear shock is dropped for any other service, you really should replace the screws with the proper flatheads.
