    Jetting Specs

    The computer Im on today has too slow of a connection to download the manual. Could someone please give me the jetting specs for a 97 SL 1050? Thanks.

    My ski has the accerlater pump. It came off a 1200 motor, I was told. Would the jetting be the same?

    No. You'll need more of a custom jetting,factory specs won't work. The 1200 carbs should be 40mm carbs.
    I have similar carbs (40mm w/accel pump) on my 97 SL.I don't have the jet #'s here,I'll get them tommorow

    My 97 SL1050 stock with the 009 cylinders 40mm carbs w/accell pump,I use;
    high jet-m=142,c=142,pto=138

    mid jet's=50 ( that is a bit rich,Wetherby ,who I originally got jet specs from suggested 42)

    low's= 65
    I'm pretty sure I have 1 turn on the low screws.

    Those are pretty close to an '01 SLX 1200.
    Depending on what type of work was done to your 1050 engine,it's a good starting point,as always you need to check your piston wash.
