A few months ago, I replaced my stock clutch perch with an ASV C5 lever/perch/hotstart assembly. I'm really happy with it, but at the time of installation, I was a little nervous. When I pulled the stock clutch perch, I realized that the new perch didn't have the same clutch switch for the starter that the stock one has.
Someone pointed out that my tail light wasn't working. I did a little digging on Thumper Talk and found this thread.
Since my battery is dead, I took it out. Without a working battery (or without one at all, in my case), the tail light doesn't work on the 250X. Whew! Now I don't have to worry about tracking down an electrical problem.
Perhaps this is more of an anti-tip, but here it is anyway.
I recently installed a new Sunline Fuel Screw in my 2004 CRF250X. In order to do so, I had to break the carb loose from the airbox-to-carb boot and the carb-to-cylinder boot so that I could turn the carb out toward me to get to the bottom of it. Boots circled below, although airbox-to-carb boot is hidden behind frame.
