    sl750 idle speed??

    can anyone help. im in the U.k and have a 1994 sl 750. i have just had a set of carbs sent over from utah. i have fitted them and the idle on the trailer is displaying 3650rpm. i have checked for air leaks, leak test ok.

    set needles to clymer manual settings,

    i know in the water it should be about 1300-1400rpm.

    any idea what it should be when on the trailer????

    thanks

    About 2600-2700 out of the water equals 1250 in the water for my ski.

    Welcome to the Hulk.

    That sounds about right. ^^^^^^ 2600 RPM out of the water

    You really need to set it when in the water though.

    Leave it on the trailer, back it into the water, and adjust the idle like that.

    thanks for the welcome.

    i agree about it being in and out of the water but the problem over here is its about £30 or $50 to even get near a lake. and im not near the sea......

    i have checked and i think the butterflies are open to wide(not from idle stop). i dont have a airflow meter to set the balance, is there a good and accurite way without taking them back off the engine to sycronise them.

    thanks

    just an update. i have reset the butterflies. they are all working and closing the same.

    it now idles around 2800, but when i get it to the water i will do some final checks. is it ok to test rides without the carb box on? say half throttle etc as as you know you cant really do any adjustments with the airbox in place.

    i have just ordered a triple fuel pump and remove the auto cock.

    thanks

    I wouldn't feel comfortable riding around with the flame arrestor off. I'd recommend tuning it on the trailer strapped down tight while backed into the water. When you think you have things right, then install the F/A then go for a ride.






    BTW... That's screwed up to have to pay $50 just to get to the lake! That's just wrong! [/URL]

    Tell me about it. but in the U.k there isnt that many lakes...... i live in the southern part and there are 2 lakes.

    both about $50 to use. at least one is only 10 minutes away....


    and im about 2 hours from the sea
