    Carb Change

    I recently purchased a set of carbs that came off of a 1995 Polaris SLX 780, planning on putting them on my 1994 Polaris SLT 750. I checked sizes and fit. Both sets are 38/34 mikuni's, but on the set that came off of the slx 780 has an additional line nipple on the top of the carbs that is smaller than the other fuel lines. I think that they are for a pulse line of some sort, however, I cannot find any name for it in any of the diagrams that I have found. So I guess that my question is since my original carbs did not have these I don't know how exactly to plumb them, without knowing what exactly I am plumbing them to. Please help, trying to get the engine running before this weekend.

    Welcome to the Hulk.

    Please post pics when asking about parts you don't know names of.

    Are you referring to the brass fittings at the top of the carbs in this pick?


    If so, those are for the oil injection hoses. Cap them off if you're not going to use them.

    That 1/8" diameter nipple is the oil supply line that was used on the 780's. Xlint has given you a perfect picture for comparison in his post. The intake in the top of the picture is from a 750, the one below it is from a 780. You'll notice brass fittings on the 750 intake but not on the 780. The 750's dumped oil from the pump into the fuel/air stream in the intake. The 780's mixed the oil into the carb itself.

    If you're going to use the 780 carbs you will need to plug off the oil lines on the carbs to prevent an air leak, or you'll need to plub the intake oil lines and use the ones on the carbs. Either way, you'll need to choose one and plug the other.
