We investigate the effect of drifting ions on compressive and rarefactive solitary waves in a five component plasma. Heavier pair ions, two components of electrons and drifting lighter ions form the five components. We use the pseudo-potential method to investigate the conditions for the existence of solitary waves. We find that both the Sagdeev potential and amplitudes of solitary waves are dependent on the velocities of the drifting ions: the amplitude of both compressive and rarefactive solitary waves increases with increasing drifting velocities of the lighter ions.
