I picked up my new 01' yz yesterday. I just want to thank all the people on the forum for all of the set up tips. I've been busy loctiting, greasing, and oiling stuff... Starts 1-2 kick when cold (so far), same with hot start. Since I would like to ride in a nearby forest, I've heard that the BMP spark arrestor is a reasonable deal ($130 or so). For those who've installed this, did you have to adjust the jetting substantially? Thanks!
