Two "machine study" kicker systems have been designed, built and installed on the storage ring of SOLEIL to kick the stored beam in the horizontal and the vertical planes, in order to investigate the non-linear dynamic of the ring with different insertion devices configurations. This article will describe the different aspects of the design of the two magnets and vacuum chambers, and of their fast high current pulsed power supplies, working with high voltage switches based on MOS transistors. The electrical and magnetic measurements will be presented. The second part of the paper will describe the modifications brought to the thick septum magnet system of the ring injection, in view to reduce the stray field seen by the stored beam. It also presents the different tunings performed on the four injection kickers, in order to reduce the amplitude of the residual bump along the ring down to a very low level. Theses adjustements are aimed to minimize the disturbances on the stored beam when operating the Synchrotron in "Top Up" injection mode.
