high idle

Is your throttle cable adjusted a little bit too tight? there should be some free play in the twist grip before the throttle responds about 1/8" of free play is good.
Check the carb to intake and intake to cylinder areas for leaks. Better yet, take them apart and seal them up with RTV on both sides.
I had the same issue with one of my bikes a while back & the remedy to it was exactly as Norman suggested, the cable did not have enough free play in it so every time I moved the handle bars left or right the engine statrted to rev higher & I couldnt get my revs down with the idle screw, gave the cable some slack & it fixed the problem instantly
I would just screw the cable adjuster IN a bit on top of the carb, or you could also adjust it at the throttle if it is not already screwed all the way in...
