Prior to picking up my new 06' WR450 I'm having the dealer deal with all the jetting woes I'm sick of doing. Basically I trust this membership more than the tech guys behind the bench. Why?..Experience with the machines. So I now ask you what in your honest opinion my new bike should be jetted for or at? Most if not all riding will be done 0'-3000' at 60-90 degrees. I'll have an FMF Q exhaust(just the canister), UNI airfilter, airbox restrictions gone, and the AIS removal kit(plugs, throttle stop etc.) along with a better fuel screw. Can someone give me a round about setup for this machine? Should I purchase the JD kit and have them install this? Thanks in advance!! Should have the blue blooded ripper this weekend or next...pics to follow! :thumbsup:

Indy has this as the setup, however I don't quite know if it fits my exact application, pipe, filter and airbox-wise.

60 to 75 degrees: 168 main, JD Blue #3 or JD Red #5, 48 Pilot, 1.5 turns, 70 starter jet, #40 leak jet
75 to 90 degrees: 165 main, JD Red #5, 48 Pilot, 1.25 turns, 68 starter jet, #50 leak jet

Try going with the richer setup first. Rather too rich than too lean.

You might want to use the below as a baseline. It is what Clark4131 suggested :thumbsup: and is more specific to the 05/06 as Indy's chart is more 03/04 based as I understood it:

Elevation 0 to 4,000 feet:

30 to 45 degrees: 172 main, JD Blue #5, 48 Pilot, 2.0 turns, 75 starter jet, #0 leak jet
45 to 60 degrees: 170 main, JD Blue #4, 48 Pilot, 1.75 turns, 72 starter jet, #35 or 0 leak jet
60 to 75 degrees: 170 main, JD Blue #3 or JD Red #5, 48 Pilot, 1.5 turns, 70 starter jet, #40 leak jet
75 to 90 degrees: 168 main, JD Red #5, 48 Pilot, 1.25 turns, 68 starter jet, #50 leak jet
90 degrees plus: 165 main, JD Red #4, 45 Pilot, 2.0 turns, 65 starter jet, #60 leak jet

Good luck :thumbsup:
