I have a 2021SFV4, If the bike sits for more than a week or so it feels like the clutch needs bleeding. Seems like if you pump the lever a bunch of times it seems to get a better feel. I heard they have. “Self bleeding” clutch, is this true? Should I bleed the clutch with a mighty vac? BTW I don’t have a manual!

Hydraulic clutches are self adjusting. Yours is a newer model , but I don’t think it’s self bleeding. Someone else correct me if I’m wrong. The problem you have is most likely a bad slave cylinder. You can replace it easily, someone else will have to tell you if it’s rebuildable.

bleed it at the slave and then bleed it at the lever. Bubbles get trapped in the master cylinder (lever).
Check a YT on how to do it. Very easy. pump, hold, open(8mm tool), close, repeat.
At the lever, bleeding take only a few reps.
Changing a slave cylinder is only when it is too hard to use the clutch, or if changing gear is problematic(even when hydraulic fluid is well bleeded) . And to my knowledge, it's something that Ducati has improved(way easier) these last years...

good luck

All better. I flush out the old fluid and refilled with new. There was a few bubbles at the lever, basic none down at the engine. I used a Brake bleeder/vacum test kit.
