I have an 03 300ex with full pipe, K&N, jetted, no lid . I just installed a cdi box and took it for a blast and it ran fine until I noticed my head pipe gettin orange. So I pulled the plug out and its white which means lean.Should the cdi effect jetting ? the shop I bought it from said it shouldnt. The plug was tan before I started. I pulled out my Dyno jet kit and it looks like I have a 140 in it since thats the only bag empty. What size should I go up to? I think my pilot is stock. It ran fine other than that. Im at sea level if that helps
