I have a new 2007 XR650R and have read about the uncorking. Where should I buy the: 1> Replacement manifold. 2> Main jets and pilot jets. I plan to eventually put an aftermarket pipe and exhaust on this bike. This bike is a project bike for the Vegas to Reno race in 2008. A group of us here in Texas, near Houston, are planning to team this bike next year.
