    99 gp1200 carb settings

    New to these forums but have had PWC's for years and I have a just replaced the engine in my Waverunner. The only changes from stock are Boysen reeds, deleted oil pump and Riva cone air filters. I am trying to find out where to set the pop-off pressure and mixture screws. Any help is greatly appreciated. Tim

    You can drop to a 95 gram spring....and turn the needles out about 1/2 turn on the highs and adjust lows for a smooth idle.
