Hi, Picking this up again. My GSXR750 - 85 with Mikuni VM29SS has the same issue , left carburator leaks from the drain. How "strong" should the spring & ball be ? If I remove the float bowl/chamber from carburators , put them on the bench and fill both number one and three with fuel they will both be empty-ish when I check them 12 hours later. It's a "slow" leakage , should it be no leakage at all i.e fuel level should stay the same ? Thank you for very good information !
