1994-2002 Polaris Big Boss/ Sport/ Sportsman/ Xplorer/ Xpress 400cc
The Polaris 400cc motor was used in many different ATV models including the Big Boss, Sport, Sportsman, Xplorer & Xpress. They were extremely popular sport, off-road and utility machines, and generally very reliable. However the one recurring electrical problem with these models was a failing stator source coil and AC powered CDI box. RMSTATOR has taken care of this issue with a plug & play DC CDI box conversion. It can be installed in minutes and keeps your quad reliable for years to come!
