I am considering going back to a WR450, 08. My dealer told me that delivery is out about two more weeks. I find this odd because the other WRs I purchased usually did not come out until Sept-Oct. I have some questions about what I am getting into. 1. Carb: The GTYR kit comes with jets. Does the carb have a fixed needle? Does the GTYR kit come with an adjustable needle? Has anyone put a YZ needle in the WR carb? Is there a JD jetting kit for the 07? Is all of this jetting worht it? or should I get another KTM that did not require any jetting? 2. Does the YZ plastics fit the WR? 3. What aftermarket tanks fit? 4. Does the 07 (08) have the grey wire? If so where is it located.
