    Superjet flame arrestor on 750 x2

    Hi,
    I want to put a stock flame arrestor on a sbn 44 carb in a 750 x2.
    It looks like the Superjet flame arrestors have hose fittings on them.
    Would I just leave those fittings alone in a x2, or is there somewhere to route
    those breather hoses?

    thanks!

    What breather hoses are you talking about? Post a picture, please.

    Re: Superjet flame arrestor on 750 x2

    Hi Chester,
    I’m not able to grab the photo from eBay, but have noticed two hose fittings on the underside of the air box on the superjet flame arrestors ( one on each side of the opening ).
    Maybe there are some without these? Is there a specific year of superjet Flame Arrestor and air box that would work best in a x2 with a sbn 44 carb?

    Thanks again,

    Dave

    I belive you are speaking on the oil injection fittings. You can leave them alone, cap them off , loop them too each other or use as a primer fitting.

    Hey, thanks 2strokesmoke. That must be what those fittings are...Iíve never looked closely at a superjet motor before.

    I'm not a Yamaha guy, but I've never noticed oil injection on an SJ. What years/engines was it equipped with it?

    I think it's to drain any accumulated water

    I am sure the flame arrestor he has is from a Wave Runner. The 650/701 single carb wave runners had oil injection, and the lines go to the base of the flame arrestor.

    Thanks John,
    Yeah...the eBay listing must have been wrong. It said the flame arrestor was from a superjet...must be from a Wave Runner.
