can a bad throttle position switch cause bad fuel range? i have a 02 zr 800 that gets awful milage and i was wondering if this could be a cause. the sled wont go slow. at 10-15 mph the sled spudders, misses, runs rough. but when you start to gradually increase your throttle from there it stays at the same speed and then it just takes off. like you accellerated fast then plains out. the sled only does this at lower speeds. at anything above 20 mph the sled is responsive immeaditly when you move the throttle.
