Did you get the bikes fixed? Was it simply an overfill issue? Hopefully all is good and the two of you enjoy the tour.

Thanks for the replies, we have several old tontis so no stranger to a set of spanner’s. Both are booked in for the first service on Saturday so I guess after a discussion I’ll know what the options are. I’m not inclined to touch it while it’s under warranty, I have plenty other Guzzi’s and Nortons to take up my spannering time. I’ll let you know how it goes.

What I am hearing is that Moto Guzzi is generous with the rear drive oil.......yet stingy with grease. :grin:

Overfilled from the factory ... common issue although I don't know why. Seems simple enough to fill correctly. My riding buddy had the same issue with his V7850.

On a different brand shaft drive bike I owned, the maintenance manual said "do not spin the wheel while filling, or you will overfill". I watched the tech spin the wheel. :rolleyes:

This is true of any shaft drive gearbox. Turning the wheel coats the gears and temporarily lowers the observable oil level. I made that mistake on my first shaft drive bike.

Originally the book called for 160-180 ml of gear oil in the rear drive. Turns out anything more than 160 was too much. Part of the recall was to drain fully and replace with 160 ml. Even new from the factory some have been overfilled. Make sure your dealer is aware of this.
