I need some jetting advice for my Yamaha 450. I used to be awesome at jetting 2-strokes but this 4-stroke stuff boggles my mind. Can anyone give me a good idea as to what jets I should be running with the mods listed below. I know you can't get me exactly where it needs to be, but if I can find the ballpark I can get it the rest of the way. So what are some of you guys running?
2004 YFZ450
High comp piston
cam mod
yosh full exhaust
K&N filter - no air box lid
Sunoco Purple fuel
Iowa Weather (70-80 degrees, 600 ft above sea level)
