I have a suzuki FZ50 that keeps bogging down when shifting from 1st to 2nd or starting out on a slight hill. The problem is remedied by going to half choke and this also gives me better top end speed. I tried adjusting the air screw and throttle screw slightly after warming up the engine but don't seem to get any results. Anyone have an idea? This bike has the same setup as the FA50 I believe.
