well i tried the needle and it didnt really make a difference could it be jet or feul air screw. i bought this carb new and never messed with the jet. does any1 know wat a 30mm mikuni should have in it for a main jet
you should do a plug chop and that will tell you if you are running rich or lean. what is your elavation there? look up the carb on sudco and find out what the jet size is.
