Hi all, I have a '04 Yamaha WR450F and a Moose Jet kit in Orem Utah 25 miles south of Salt Lake City. I have messed around with the main jet trying the 132, 134, 136, & 138 mains to dial it in but I cannot seem to find the sweet spot. The 136 is probably the best but I am fairly certain that the pilot circuit is a problem also and I am guessing that the two circuits are interfering with each other around mid throttle. (FYI I am around 4700' in elevation) Bottom line... I need to find someone who can really dial this in and I am looking for recommendations. I have also wondered if there is a better jetting kit out there that isn't so problematic that even a neophite like me can dial in?
