  We investigate the real-time spin response of the $S=1$ Kitaev model upon
stimuli of a pulsed magnetic field in one of the edges using the exact
diagonalization method. It is found that the pulsed magnetic field has no
effect on the appearance of the spin moments in the quantum spin liquid region,
but induces the spin oscillations in the other edge region with a small
magnetic field. This is understood by the existence of the itinerant
quasiparticles, which carry the spin excitations without the spin polarization
in the quantum spin liquid state. This suggests that the spin
fractionalizations occur in the $S=1$ Kitaev model as well as the exactly
solvable $S=1/2$ Kitaev one and the fractionalized quasiparticles play an
essential role in the spin transport.
