Swing arm removal advice

[Fazerider]

In the guide it says this process destroys the pivot arm bearings, you can't do this process just to regrease everything then?

The sleeve slides out without damaging the bearings (provided you take care not to introduce grit) so you can regrease them easily enough. The bearings are a tight fit in the swing arm and get wrecked if you have to drift them out, but you'd normally only be doing that if they're knackered anyway.
