hey guys, have a 93 gsxr750w, runs fine, but uses way to much fuel. carbs have been taken apart and jets checked, balanced, floats checked. Valves have been set and are in spec. u can smell the raw fuel when its idling and it doesn't miss or studder, feels kinda lazy when your accelerating. and it fuel fowls the plugs in about 2k or so, and doesn't burn a drop of oil. 2 shops i have had it at, cannot figure it out, anyone have this problem??
