Hello everyone, I just got my 400ex today, I went from a 300 to it. I love it!!! It just is way better than my 300. What I was wanting is that there are so many little tips and stuff for the 400, a lot of which are posts in this site. Could everyone who knows anything about this post? I'm sure the big number of people who own 400's would appreciate it too. Thanks! And also, I'm curious about the throttle adjustment. How do I know if it's not adjusted correctly? It is a 2000.
Take and turn the screw out on the handlebars until the idle increases. Turn the handlebars and make sure the idle don't increase. tighten it again and hold on. I first did it by looking in the carb. but noticed a big difference by going this route.
