I know alot of people ask this question but the my result from searching the forum kind of leave some gaps. So I'm going to ask anyway.... I have a 2006 XR650L Stock.....I scored a WB E2 muffler and Big Gun Header for cheap money. Smog stuff already removed. Airbox/filter is stock. Carb is stock. What is the hot setup for jets with this combo?? I'm assuming that the "Dave's Mods" will need to be done. I live in the Northeast area so elevation is on the low scale.
