I have recently has my suspension replaced by Lukasz at T-Tech Suspension. I decided to purchase the rear spring in addition to the quoted spec/price (when we looked at the rear spring, although it was not "bad" there was signs of corrosion starting, so whilst the bike was stripped down, it was a no brainer to have a new spring as well.
Due to the "default" equipment I carry, Lukasz increased the preload on the rear unit. I now use "One-up" instead of "One-up with luggage" & the handling is vastly better & easily noticeable. We discussed the front unit & I made a spring change to that as well. So my suspension set up is "One-up" & "normal" damping.
I secured the rubber "mat" as shown in the photo, I have been out yesterday in the numerous downpours we had, since inspected the bottom of the rear unit & whilst it is not too cruddy (mainly due to the front mudguard I would suggest) I can see that over time, if not cleaned regularly, the same fate of the bottom bush seizing may happen.
To try & overcome this, I have purchased a section of 2mm rubber (200mm x 200mm) for £6 & will over the next few days get the bike raised on the ramp, drop the silencer out & attach a portion of the rubber to the front side of the swinging arm (opposite the matting) to protect the bottom of the unit.
When I know the "farkle" is working, I will upload another photo. (Apologies, I do not know how to rotate the uploaded image into the correct orientation)
Take care & stay safe all
