I have a yfz carb and it won't fit the 400ex. It's to tall for one and the fuel line on the carb would hit the frame. The airbox boot is bigger than the intake on the carb. I did a 450r carb and it worked great. Check out the 400ex section were I put pics on how it looks.

What are the benefits of running a 450r carb?
