Taking a trip next week to Red River NM. Altitude is around 9k. Dealers in the Dallas area claim they have no idea what size jet to use and that Polaris does not have Jet specs sheets for the youth quads. I called a dealer in Denver and they too did not know which jet to use. I even had one dealer tell me that Polaris did not make a high altitude jet for the SP90 and they recomended putting a wire in the jet opening to restrict fuel. My SP500 performs OK, however I'm a little concerned the the 90 will not function at all. Anyone have advise ??????????
