wr426 jetting...im lean! help please!

2 posts in this topic

just scored a mint wr426, street titled, ridden in tennis shoes by the first owner for its entire life. i have removed the throttle stop screw, unhooked the grey wire, removed the airbox lid and installed a fmf powercore 4 slip on exhaust system. fmf said to go up one size on both the main and the pilot jets...im lean and im wondering where i should be with my jets - i had a 185 main that i threw in and left the pilot at the stock 42. i also went out one more turn on the idle mix screw,as their jetting suggestion sounded a little lean . i ride at sea level. does anyone have any ballpark specs that will save me the trouble of swapping jets in and out? thanks, rick s.
