You seem to have a good grasp on jetting the 450.I have a 05 WR450 that has been uncorked and JD jet kit.Can you recommend a starting place on jetting this thing.I Will ride elevation 2000-4000' and 30-45* until summer then 6000-8000' and 70-80* Best guess is ok.

Thanks lug :cry:

Punch a couple of 1" dia holes in the side of the airbox and place aftermarket foam plugs to help the uncorked jeting work better.

30 - 50 degrees @ 3,000 feet elevation: 170 main, JD Blue #5, 48 pilot, 72 starter jet, #40 leak jet

50 - 70 degrees @ 3,000 feet elevation: 165 main, JD Blue #4 , 48 pilot, 72 starter jet, #40 leak jet

70 - 90 degrees @ 3,000 feet elevation: 160 main, JD Red #4, 45 pilot, 68 starter jet, #50 leak jet

50 - 70 degrees @ 7,000 feet elevation: 160 main, JD Blue #3, 45 pilot, 68 starter jet , #50 leak jet

70 - 90 degrees @ 7,000 feet elevation: 155 main, JD Red #4, 42 pilot, 65 starter jet, #60 leak jet

Those are all tested with uncorked stock pipe and air box mod holes to increase air flow into the air box. :cry:
