I finally got around to installing a Zip Ty fuel screw and #50 pilot jet on my Canadian model 03 WR450. I'll post my info on the jetting database once I get the bike out for a few hours of riding. Right now at 1 3/4 turns out on the fuel screw, the throttle response is much better and starting is easier. (1500ft) My question is: which direction do I adjust the fuel screw when I go to higher altitudes? I realize that I will only get some improvement without changing the jets for altitude. Used the search engine, but couldn't find the specific info on which direction. In or out? Thanks.
