Friend of mine has a 94 750 Virago. Bike runs great up through the gears and will cruise 50mph and faster just fine. However,at 30-40mph,engine coughs,backfires,stumbles very bad. As soon as you twist the throttle everything is fine. Bike has new plugs and everything else seems to be in order. Thanks in advance for any help!

The carb or carbs have like 3 ckts low throttle med and full wot. Sounds like the ckt that controls midrange is clogged, probably from gas that has varnished from sitting.
