I have a 2001 Yamaha warrior that I just purchased. It has a stock engine with alien exhaust and K & N air filter. After looking at the manufacturer of the exhausts website they indicate to put in a #45 Pilot jet and #150-#155 main jet. After doing general maintenance, spark plug replacement, valve adjustment, carb cleanign, etc. It seems to hiccup through the air box(yes the cover is off), and while warming up I it seems to idle a little rough. My question is should I install the #45 pilot jet in place of the #42.5? If so where can you find that jet? (Carb is not the elm... its the OEM).
