I have a 400ex with a R4 full system and run it with the airbox lid off. I live in Wisconsin near Green Bay. I have a 168 K main jet in now everything else stock. (in carb). How should i have it jettet and what carb adjustments do i need. I am going to have my local mechanic show me how to do this though. I just want a piece of mind.:confused:
