- August 26, 2017, 10:03:28 AMHere are pictures of the swing arm. I found no grease in the u-loint and propeller shaft spline and very little left in the sliding joint (the remnants of white lithium were previously used). The u-joint works fine. All splines are in excellent condition. Everything just needs grease. When disassembling I made the mistake of pushing in the pin while pulling the swingarm out. Almost lost the pin. That does not need to be done. Just pull on the swingarm (after taking the bolt out) and the propeller shaft will stay in place then you can remove it by pushing in the pin. The propeller shaft (10-6 final drive manual) can be lubricated somewhat by just pulling back the rubber boot and spraying a white lithium grease into that area for maintenance between tire changes. I recommend that it be done according to the manual or every rear tire change. Whichever comes first.

Also when you re-fill the rear drive unit use a high quality synthetic or natural oil and put in the recommended dose of Moly which can still be ordered through MGCycle (Moto Guzzi). Do not put in any Moly to your engine oil! You can on Moto Guzzi because they have a separate gearbox.

- August 23, 2017, 11:38:44 AMI'm just about to put on a rear tire (ME888) and while I'm at it I am also going to pull swing arm/driveshaft off and re-lube. When the U-joint does not have any grease in/on it it will create a vibration. I have had a couple of Moto Guzzi's (still have one) and they were notorious depending on the day of the week and whether they were on strike, that many of the U-joints did not get lubed properly. That kind of changed with the V11 which had fittings to insert grease in although one was almost impossible to get to. Also since I used Guard Dog Moly (no longer in business-a shame) spline grease on the spline on the rear wheel it smoothed out considerably.

- August 23, 2017, 01:59:38 AMHave developed a thrrruummm at certain times - if I change gears I can make it go away. Feel it thru the bike as well. Sounds/feels like something rubbing while it rotates. Sounds a little like, when as kids we used to attach a piece of cardboard to the bicycle spoke to make noise. I had a Moto Guzzi throw a universal drive shaft joint , and I was picking up on it before it happened.
Head bearings and front wheel bearings recently changed.
Anyone had similiar problem
