    Low Idling RPM's on STX R 1200

    I recently purchased a 2002 STX R 1200. Great compression in all the cylinders, took it out to the lake last week and it ran great. When I came home I flushed the engine and noticed that the idling RPMs were at about 1,100 and it should be at 1,800 per the owners manual (out of water). The previous owner installed a waterbox on this so I am wondering if that would affect the RPM's? Do I need to adjust the carburetor so it is back to the manufacturers recommended idling RPM's? There was also the slightest amount of hesitation when accelerating too so I am thinking that might be a sign that the carb needs some fine tuning.

    Set the idle speed in the water and don't worry about it.

    dont pay any attention to what it is idling out of the water, you should be only concerned about the idle speed in the water. i keep mine around 800-1000rpm when in the water
