    HI Lo Screw Location GP1200R??

    Trying to find the hi/lo speed screws on stock mikuni 2000 GP1200R.. The caps have been removed by the mechanic that rebuilt them. I have not removed the air box yet but I can not see any screws on the side of the carbs that faces up when installed on the motor. Any help or pics?

    Thanks

    Welcome Forest.Did they rejet the carbs and install T handles? Here is a thread to read about carbs.http://www.hydrotoys.com/gpr/tuners/...orAssembly.pdf

    They did not install t handles. I will check out the article to see if it talks about where they are located without the thandles

    The low speed is located on the bottom as installed closest to the throttle plate. The hi speed is located on top closest to the choke plate. The body is marked L and H.. With the carb vertical the L is the lowest and the H is highest.

    Forgive my ignorance but I do not know where the throttle plate is. Are the low speeds on the bottom facing the bottom of the hull when installed on the motor? Maybe I should remove them to adjust??

    I did and nothing says throttle plate. They must be on facing the bottom of the hull because I can not see any adjustments on the side facing up towards the seat.

    Forest in the pics I posted the first one is of the bottom of the carb and that is where you low speed screw is. The second pic is the top of the carb and that is where the high speed screw is. can you snap a pic of your carbs?
