I am going to be putting my new Yoshi pipe and K&N filter on my 400ex this Saturday. I know I need to rejet the carb. I have the dynojet kit with all of it's jetting instructions. But, how much work is it to the the carb off of the bike? Do I need to remove the airbox, and side plastic panels, or is there a secret to getting the carb out easily? I'd like to hear from people who have done this job themselves. Thanks!!!
