I recently purchased some additional jets for my 2001 KDX 200 and I'm attempting to lean my bike down from it's rich condition. I've read the jetting recommendations from CD's website, but still have a general question. Is there a relationship numerically with the main and pilot jets. In other words can you run a 38 pilot with a 155 main or is there a rule of thumb regarding separation of the two jets sizes?
