I'm not there yet, but I didn't have a clue how to flush the brake fluid out of the hydraulic clutch.
I researched it by watching a video on Fix My Hog. They are putting together a video on every item on the maintenance checklist for the M8.
It's a little more involved than flushing/bleeding brakes, as you have to remove a false cover on the right side of the engine & on the touring model they were working on, they had to remove the exhaust heat shields to get the cover off & access the bleed valve.
2 items I learned were that the clutch system seemed to get dirtier than the brake system & unlike the brake system, were the fluid level in the master cylinder goes down as the brake pads wear, in the clutch system, the fluid level rises, so that is something to be aware of & keep an eye on, as it could lead to an over pressurization situation.
