I completed the rear suspension job over the weekend. Thanjs for the input on my lift especially. I appreciated the Skylift, even though it does get in the way. I opted to not service the swing arm pivot's 1 needle bearing. I will look at that in 16-32k more miles.
It seems two of the three bearings in the relay arm didn't really need lubricated at all. The little clear plastic sleeve inside retains grease and prevents most water intrusion. The one without the sleeve was a little more dry. I lubricated all three anyway with fuch's waterproof grease. I also cleaned & lubricated u-joint/output, drive shaft, and diff splines with loctite moly.
The only things that I have left to do maintenance-wise is spark plugs (even though 21k is a bit early), & replace my brake and clutch lines with steel braided. I know Yamaha recommends replacing the lines every so often at an overly-cautious interval. I like to convert to steel braided for the brake feel on every bike I own. I usually use Galfer's lines. If there's any go-to lines for the FJR that anyone wants to share, feel free.
