Out with the RED and in with the BLUE. Im going to be picking up an 06 450 in the next week and am wondering about the carb mods everyone is doing. I have read about the lean condition. Is the JD jet kit worth it, or should I just pick up some jets and save some money? Is there anything else I should know about also? Edit: What about chain and sprokets? Can I just get a chain and use my stock sprokets?
