    Simple Return Line Restrictor, what size jet?

    http://www.greenhulk.net/forums/show...t=12649&page=2

    For SL 750 with the single K&N arrestor, Boyesen Power Reeds and primer with choke shaft removed.

    Just looking for a starting point.

    Thanks!
    Matt

    Did you confirm yours is missing? It should be inside the return fuel line about 3/4" past the carbs.

    xlint89, Yes sir, I did. As I am taking the machine apart, I am finding more and more surprises! May have to post in the "project" forum!

    Also, if I tap the last carb nipple, do I have to drill a larger hole first?

    Or, should I just put a stock one in the hose?

    You should be able to tap the last nipple, a 780 comes like this already. Just use the proper drill bit for the tap and make sure no filings gets into your carbs. Have you PM'ed CrazyA? He's been generous enough to provide restrictors to some people. Often free of charge!!! You can't beat that with a stick.

    .018 is the hole size. Not sure what size jet that comes out to be. FYI: the restrictor is what gives you fuel pressure at WOT, that's why it is important to have one installed.

    jet size

    Most Polaris watercraft can use a Mikuni main jet #90. That is merely a starting point, and will require further testing by the tuner. An average range is #60 - #100 Mikuni high speed jet. It can be installed anywhere between the carbs & the fuel tank.

    Regards,
    Randy
