take the bowl off the carb, pull out every jet, remove the float, pull out the rubber tipped needle, and use a straw with carb cleaner and spray every vessel u see. If i remember right, mikuni uses round jets apposed to kehin hex jets. you should be bale to see through the jet when its clean. also, check the end of the rubber needle and make sure it isnt dry rotted torn up, it should be pretty pointy. if still no luck, it may just be jetted wrong. Look around online and see what the stock jeetin it came with. temperature, humidity, and elevation will all play a roll in your jetting. should just be a main and pilot jet, and i doubt it has an adjustable needle.
