  6. Petcock leak

    Carbs and Fuel System
    So, I recently laid my bike down at high speed and I went from smelling gas, to a visible leak out of the petcock. Now it could be just not seated firmly because of the accident, but I don't think so. It only leaks when the engine is running and in the ON position. Any thoughts? I know, pretty...

In the event that I do need to buy a new one is there one anyone recommends? The strange thing is that mine...

    So I bought my 2000 V750 back about three weeks ago (have not had a chance to ride it yet) I changed the oil and was a milky brown color.
