If you adjust the lever or cable so there is little or no freeplay, the clutch may not be fully engaging (grabbing) when you release the level, and it will slip.
If you have way too much free play then when you pull the lever all the way to the grip, it may not be fully open (disengaged). Then the bike would be pulling and trying to creep when you stop without putting the brakes on. That would also make the bike hard to shift, because the gears will have torque on them when you change from one to the next.
Either extreme is not good, but anywhere in between is ok. Vstar bikes tend to have very narrow friction zone, so you have some latitude about where you put it.
whenever you adjust it your muscle memory will take a while to get use to the new response.
To the best of my knowledge, as the clutch plates wear down the freeplay gets smaller and smaller. If you keep the lever all the way out with very little freeplay, you will need to keep an eye on it and adjust it more frequently.
