Does anyone actually use/need it? I have never needed it on my '02 WR426; it always fires up first kick. Some people must use it, because I've seen people mount it to the handlebars with a DRD kit, I believe it was. Possibly I'm running a tad rich? I went to the YAMAHA dealer and noticed it was not there on the '04s. Is the carb different, or was it a slightly useless feature to begin with?
