I have the EPI clutch kit on mine. It does really help. In shifting also. If you do alot of water riding you are also able to turn up the idol on the carb so the foreman wont suck up any water in the motor. All it does is engage at higher RPM's. Works good in the mud I got first place also at the north east mud sling mud bog for atv's and there were alot of atvs out their.
