We just got my son a yz85 about a month ago, and it is constantly flooding. I believe he is riding it fast enough. So far I have leaned out the pilot screw, went 1 leaner on the pilot jet, and 1 leaner on the main jet and still had to go with a hotter plug. We're running 30:1 at approximately 1200 feet with temps of 35 to 60 degrees. Any suggestions what else to check? Also has anyone seen any articles telling the ideal set up for these bikes. Thanks zeke
