The bike came with an eBay carburetor, from what I have read and watched online, the jet on the exhaust side of the carb is the fuel one. It only has this jet, and the idle jet exposed. It also has a k&n pod filter. How to I know if I need a different jet, and how do I figure out what size to buy? I've read I would need bigger than stock with the pod, I'm just not sure what size is in there to know what size to buy. Thanks in advance for your help. I don't know much about carbs, but I'm trying to learn.
