Tuning a clutch for better engagement and feel

On the street, we use our clutches to pull away from a stop, and once underway , either speed shift or use the clutch briefly for gear changes. In stop and go traffic, in first gear, we are on and off the clutch and its situations like that where we notice whether or not our clutch is smooth , heavy, light, grabby, etc.
I have taken up Trials riding, where clutch performance is ultimately critical for competition. Most sections are run in one or two gears, with the clutch being modulated heavily. I also ride hard enduro on a 2 stroke , which also forces heavy clutch work.
I had a grabby clutch in my trials machine, and it was notoriously sticky when cool. Furthermore, the clutch pull was heavy, and fatiguing after a day of practice. I made a few changes that made quite a difference.
This may be relevant if you are experiencing clutch challenges with your motorcycle.
