    no, no, no

    OEM grate is not safe on a modded ski, it allows teh pump to get overstuffed, which can cause the ski to jackknife on you

    You missed this question? If you have a 800 grate you WILL spin out of the hole. if it is a 1200 that's not and issue.
    If it is a HO pump you will need a 14/20 DF If it is a 03 pump you will need a 14/20 concord.
