    Ok real funny guys, Where are you hiding them Suzuki 13491-44500

    Hello Gentlemen,

    my 85 450GA is having a small fuel leak from its https://www.partzilla.com/product/suzuki/13491-44500. I believe it's some form of surge valve. Where are they hiding? I cannot seem to find the rubber OR the complete assembly anywhere. Does someone have 50 in their basement? Either way let me know and I will GLADLY pay you. Otherwise does anyone have any idea how I could make a new one?

    How about buying a thin sheet of viton rubber, then cutting out a new diaphragm? Depending on size, an old carb slide diaphragm could also be repurposed. A doable project, but not a simple one.

    Edit: if you search eBay for "accelerator pump" and then narrow the search to "motorcycle" parts, you will find several options that may work. Honda (Keihin) has a very similar part. It seems to be 29mm diameter, though. I think yours is closer to 25mm? Anyway, you may want to dig around to look for something that can be modified...

      I am seeing what you mention in the second part of your message. Maybe a modified part would be best here.

        Think something like this would work?

        Pop pop, pop!  If you are hearing that upon snapping the throttle closed, you may have an issue with your carburetor air cut off valve. This valve cuts off air to the pilot circuit during deceleration, thus enriching the pilot circuit and reducing

          I ordered the ebay one mentioned above but they appear to be the same part. The suzukimatic and hondamatic were essentially the same bike with tweaks it seems.
