hi guys and gals . i am new to the site and i need some help if possible . i am new to banshees but not two strokes i bought a banshee and have some issues . it a 1993 as far as i know its stock it does have a boost bottle . . first issue is . in second gear it slips around half throttle . i adjusted the chain and still no fix . only second gear . next is a surging issue . i think i need to clean the carbs . if i leave the fuel on the right carb leaks out the overflow tube . it idles fine with no problems . i replaced the plugs and it was not the issue .
