Question about Yamaha YZ 450 F Motorcycles
Are you turning the idle screw or the smaller inset mixture screws?. Check to make sure its not the idle screw. Typically the idle screw will have a spring holding tension against it. Also check to make sure there is a good seal between the carb boot and the Cyl head. It could be sucking extra air past this and causeing the engine to rev.
