    What oil will you be using?

    Most guys run 40:1 pre-mixed oil on the non-triple-piped Polaris engines.

    32:1 during cylinder break-in.

    i run 50:1 with amsoil dominator on both my triple piped skis.if the guy set it up tight on the jetting then adding more oil will lean out the fuel mix.if you go with more oil open the highs a 1/8 turn to be safe

    It's syn "blend". I know, I wanted full syn but it was the best i could find. $40 a gallon. "highs" are front facing screws or rear?

    Should also be noted...It could also be tuned for Lake Mconoghy, Ne (3,200ft elevation). I won't ever see less than 4k and this weekend will be over 7k.
