    Sl750 must feather throttle to get on plane

    I have a 95 SL750 with the usual upgrades, when it is warmed up it runs great, but after sitting a while when first started I must feather the throttle to get it to go, if you just try to open the throttle up it boggs down and dies, but once it warms up you can go from dead stop to a wide open start with no problem, is that just the nature of the beast, it must be warmed up a little bit? or do I need to do some adjustments?any ideas, thanks,

    It's not "nature of the beast", but you should ALWAYS warm the engine before running WOT.

    Try checking your low speed screw settings VS. the specs for your model year.

    Pull the choke and see if it works better.
    If it does, you'll be looking for a lean running condition. Fuel lines kinked or swollen, fuel valve, plugged jets, stale fuel etc.

    Yes, 1/2 turn OUT from a LIGHTLY seated position on the low screws.

    I took off the Vortex Air breathers and I can barely get my fingers on the needle valves, no room for a screwdriver, any ideas?

    You should not need a scewdriver to adjust the low speed needles. They are at the base on the forward end of each carb. I have big mits and I can reach them without too much fuss.

    Right!!! And that TDR waterbox may need a touch more fuel up top too.

    Turn your high speed screws OUT another 1/2 turn from stock spec.

    Should I turn all 3 high speed needles out the 1/2?

    These were the parts that were added before I bought it,


    Oil pump removed; runs on 40:1 pre-mix
    Triple outlet fuel pump upgrade
    Aftermarket intake grate and rideplate
    Toxic reeds and reed cage spacers
    Ocean Pro Vortex flame arrestors and covers
    TDR waterbox (it's not real loud, sounds good)
    UMI handlebars, Renthal grips and finger throttle

    I also have a Ocean Pro aftermarket head included (not installed)
    I have read mixed reviews about the Ocean Pro Head,
    I know I would have to run higher octane but some forums I read said that it is not worth it putting it on? and it will be the death of the ski,

    thanks,
