I have a 2003 Seadoo gtx di. For some reason it won’t go pass 5,00 rpm’s. Idk why but I cleaned the reed valves, rave valves, intake valve. Replaced the air sensor, throttle sensor. I just cleaned the injectors and still nothing. I have a check valve coming but I don’t think it’s that. It believe it maybe a gas or air intake issues cause it bogs out sometimes when I throttle it. Any info would help. Thnx
