I tried it at the bar end and got no real improvement . i removed the tank (real simple) and adjusted the cable end there. You need a 8 and 10 mm wrench. Teh tank comes off esliy, Use pliears in the snap type hos clamps and the fuel line a a squeeze type fitting. You break the cable jam nut loose, Back it off remove the cable from the holder, Adjustthe lower jam not down adn reinstall. Check throttle and readjujst as necessary. i haev no throttle play now (dont care what suzuki says abdout play ites my bike) Tehn use the bar end to fine tune.
