    97 sea doo speedster engine trouble

    Hello I am having a bit of trouble with my 97 sea doo speedster. It has fresh motors , wear rings and pump seals, rotary valves both set 147 degree. The port motor pulls harder then the starboard. The throttles are even adjusted. When both engines reach 4500 to 5k the port motor power band just takes off leavin the starboard at 4500 till you give it more throttle. So At 3/4 throttle starboard engine lags til full throttle. Also the port side tops 7200 and the starboard only tops 6400 to 6500. Other then that it runs flawless cruising around. Any help would be awesome!
