Im new to the site and to motorcycles. I see alot of people talking about carbs and jets. I want to know when would i need a bigger or smaller jet? What am I looking for in the engine's performance in order to know if i need a bigger jet or smaller jet? How do I know when to look at the jet? How does changing the Airfilter effect jets? When Do I need to mess with the Air fuel mixture? I know it alot of questions and theirs alot of experience floating around here and would get some knowledge droped on me. Great Site!
