I do the above, but I go further. I take the 6 bolts holding the clutch and disk assembly together out and clean the clutch disks with a fine stiff wire brush, then spray off with brake clean, I also lube the bearing race where it fits into the madril with some lite oil, just a touch. This is after every weekend. Make sure to put the clutch disks and floater in the same positions or it might cause the clutch to chatter.
Once a year I rebuild and surface the pressure plates if needed, they are usually grooved, and replace with clutch disk with new.
