    Clutch slaves are self-adjusting, just like
    brake calipers. As brake pads or clutch plates wear,
    the piston(s) move out -or in, to take up the slack.

    If there is no air in the system
    and adequate fluid, the piston will move out
    farther with each lever stroke till it reaches
    something to stop it, or it's pushed all the way
    out of it's bore, or all the way in (see next paragraph)

    With clutches that are rod operated thru the
    clutch basket, clutch wear gradually moves the
    rod toward the slave, so the rod effectively gets
    longer, not shorter. And, as the clutch wears, master
    cylinder fluid level increases. So, if fluid becomes too high,
    clutch operation is affected; there must be air space
    in the master.

    I check the operation of rod-type clutches (either
    cable or hydraulic) by pulling off the cover to see if
    the clutches open/close adequately/smoothly.
    Warped steel plates, grooved baskets,
    gummy oil, improper assembly/etc can cause
    neutral to be elusive....

    Is it possible that adaquate but not enough fluid in the master could cause an issue....what is weird is it seemed to have plenty in there, but I filled it up so the it was close to the top of the right side...some squeezed out when i put the cover on, but there was probably still room for air....i didnt changed the rod any, but now the neutral seems to be working

    Your post does not mention what year your bike is, but clutch master cylinder issues are a known issue with some years. I would rebuild it and be done with it.
