Greetings . getting ready to lift my 017 30k miles Cali 1400 to access and remove the gearbox to have a looksee at the clutch assembly and replace ( at least) the disc as a matter of course. No abrupt jerky release or other functional issues present , in fact quite possibly the nicest Guzz acting i clutch yet for me after saddle time on Loop, Tontis and a number of Guzzi clutch replacements in my rearview mirror. Only issue is an occasional slip between 4/5k rpm under hard accell. No changes in gearbox oil level, or burnt gear oil as I have noticed in the past when the clutch rod seals leakage and or too high oil level were causing the problem. The choice of clutch disc are the original ( AP) or a Newfren aftermarket replacement. Can anyone who has done a 1200 8V or 1400 clutch replacement share their experience or what they have used?
