A thread like this exists over in the YZ/WR 250F forum, and I thought it would be nice to have one here. Here is the template: Model Year: Main jet: Pilot Jet: Leak Jet: Fuel screw (turns out): Needle model/Clip position: Airbox mods: Pipe: Altitude where you ride: Temperature where you ride: Other mods: Degree of satisfaction: Try not to fill the thread with other topics. Jetting questions should probably be directed to the Jetting forum. This will help make jetting searches more productive. So go ahead and post your specs!! Mod: Sticky?
