\featherDurations { <music> } doesn't change the length of <music>  as
a whole. If you remove \featherDurations the barcheck should not fail.
It does! So there is something else to change.

Well, I don't know what you intend, perhaps:

percOne = \drummode {
        \tempo 2 = 60
        %\tempo 2 = 45
        \time 5/4

%1
        r8\mp
        \times 2/3 { wbh16 wbh r16 }
        \override Beam #'grow-direction = #RIGHT
        \featherDurations #(ly:make-moment 1 2)
        { \times 4/5 { wbh16[ wbh wbh r16 wbh] } }
        r2. |
}


\score {
        \new DrumStaff {
                \percOne
        }
}

\version "2.15.27"

HTH,
