I am getting a wr 450 and am trying to decide to go big and get an 07 or save some cash and getting an 06. I really like the changes this year with the 07 but looking at the carb it looks like a huge pain in the booty to get to the jets. Is the best access through the seat, rear or a secret compartment? I live in CO (10000 feet) and enjoy taking trips to moab and AZ. This requires adjusting jetting often. My little 03 wr250 jets are easy to get to and am really concerned about taking apart the 07 450 to get to the heart of the thing. Am I freaking out over nothing or should I just bite the bullet and learn a differnt carb?
