I have a lot of respect for Makis, he definately knows his way around these bikes. But I think you need to take into account the history of the bike. What kind of service has the clutch had so far? If you're uncertain, then disassemble and inspect closely.
I didn't know the history of the first 15,000 miles of my bike, and come to find out, I needed all new rubber, cause of a couple years of water contamination in the fluid, it had turned into a gooey peanut butter in the bottom of the slave cylinder. You cant flush that out, cause it sits on the bottom and the bleeder is at the top.
I suggest the following, (having just done it last summer) a master kit, which will include some cups, a seal for the push piston, and a new main piston. It's part #3 in this diagram
. For the slave you should only need parts 13,9 & 6 from this diagram
Inspect the collapsable diaphram in the master cylinder's resevior, I needed to replace that in my bike. I couldn't even tell untill I held it next to the new one, and saw a dramatic difference.
