    gp1200r only hitting 6500rpm HELP PLEASE

    THE SKI IS BASICALLY A RIVA STAGE 2. IT ALSO HAS THE CHOKE AND ACCELORATOR PUMP REMOVED; REJETTED 110,125. IVE CHECKED THE CARBS ENOUGH THAT I DOUBT THEM AS A POSSIBILITY. I ALSO TESTED THE WIRES AND COILS FOR PROPER RESISTANCE. ALSO HAS NEW ,CORRECT, PLUGS. THE BOTTOM END POWER IS STRONG. OH YEAH POWERVALVES HAVE BEEN REPLACED WITH [email protected] AND ALSO THE WAVE EATERS. AND YES THEY ARE OPENING. NOT SURE IF THEY OPEN ALL THE WAY. THE ONLY PROBLEM I SEE, THAT HASNT BEEN LOCATED; NO PRESSURE AT GAS CAP WHEN OPENING. HELP!!MY WAVERAIDER IS FASTER THAN MY GPR!!!

    Welcome to the forum.
    Have you tried opening the valves manually and running the ski?
    Fuel flapper removed in tank?
    Compression test good?
    Was the ski running good and then started acting up?

    gpr

    +1 To the gpr guru Woody. Just out of curiousity is this still a single fuel line feed setup? Is the breathed line clear? Fuel filter or filters if duel setup ok? Also one last thought. I imagine this has a d plate on stock stinted but for the heck of it did oem cat brake up before removal and maybe some pieces made its way down to water box? This is weird also welcome to the forum.
