[QUOTE="trist007, post: 1269663, member: 80704"] I have a 2008 KTM 530 EXC-R. I bought it in Austin, Tx. They said that the bikes run lean out of the factory so they put in a new jet to make the bike run richer. Now I'm finding out that the bike is running too rich because the spark plug is fouling. I have the manual but it doesn't explain how to adjust the jet. I was wondering if someone could explain how to adjust the jet. From my current knowledge about adjusting the jet, I'm thinking of detaching the fuel hose from the fuel tank to the carb then unscrewing all the bolts that are holding the carb down. I take the carb out and look for where to pull out that needle. Then I remove the clip from the needle and move it up maybe 2 spaces up to make it leaner. Then just put everything back. Can someone correct me if I have the wrong idea? I got a few questions. How do I know which direction to move that little clip to make it leaner. I need a point of reference to know that I'm making it leaner. I'm assuming by moving the clip higher the needle goes into the carb deeper thus allowing less fuel to flow so it would run leaner. Also, can somebody explain to me the difference between the pilot jet and the main jet. I'd be adjusting the main jet? Which jet do you guys think that the dealership changed? Is the pilot jet the one that is just for idling? Thanks guys. [/QUOTE]
