I just installed a new factory pipe and I am trying to get my ski tuned, I pulled the carbs off the ski to put in the recommended main jet and set the high and low speed screws to the factory pipe settings as well, know that its together how the heck do you get to the high speed screw on the forward carb to make adjustments. The low speed has the little knob on it to do with your finger but the high speed doesnt. Just wondering how every one gets to the high speed screws.
