Just bought a 07 xrs , and took my first ride , ran like sh-t. No power, no RPM, Had clutch updates done ! Messed with clutch settings, tried my buddies secondary still nothing.Talked to a guy in the hot tub and he said check the hose that runs your power valves, sure as hell it was off , Second day was great! Lots of power, ran clutch in #2 position and pulled 8300 all day . Thanks who ever you are .
