Have backed adj screws out full 3 turns trying to get it to run richer, pulled plugs still very white, compression on both cylinders 110psi. Takes awhile to get full speed at 43 mph, 800 should run faster (55-57) right? Rave valves open and close on trailer but not on lake test. I,ve disconnected rave valves at wiring harness, so valves are closed and have no problem accellerating on the lake. Ski has less than 35 hrs on it. Could this be wrong jets from factory. Any help is appreciated, THANKS.

Re: 03 gtx 800 runs lean

Cleaned them, drained tank and filled with fresh fuel, flushed the lines and cleaned all filters. Found leak on
pressure gauge, have 125 psi on both cylinders. COULD this be a problem with the MPEM . ThanksComment
