I live in Oregon and have had my yfz for about 2 weeks. My question is this what jets are you using and gow far out on the airscrew? Right now i have a 165 in with a 45 pilot and 6 pos on the needle . It runs ok but not great. What r u running Im at about 200 feet but most riding is at sea level. Thanks PS i have the airbox lid off and the baffle out.
