Purchased brass elbows from Atlantic Jet Sports for my OEM 61x carb. These fittings work for the inlet however I need fittings for the return as well. Does anyone know where i can find 7mm press in brass elbows? The elbows I purchased are 6mm. Thanks.

Did some searching and found a lot of info on small plug style duck bill valves and versi plugs. Versi plugs look great however the they inhibit flow. Has anyone used a 2" insert able duck bill valve to stop a scupper from leaking? Duck bills seem to be a cheaper option without sacrificing flow...

I have a 300sx conversion. Love the hull but still getting it dialed in. My back is hurting when I ride it. I know handlepole lengths are a preference but not sure if I should lengthen mine.
