    Recently drilled out the rivets on my petcock to get to the leaking x-ring. Has anyone found a source for a new x-ring and the flat 4-hole selector seal? If so, what size x-ring fits the 86? Where do you purchase the 4-hole flat seal?

    Thanks

    For the X ring you may have to try viton o rings from McMaster Carr. For the 4 hole you can start with Honda's of the same vintage. I was able to replace the 4 hole gasket in my KZ400 petcock with an early CB750 gasket.
    Post the measurements and a pic of the x ring and a pic of the 4 hole gasket next to a metric ruler.
    I may be taveling this same path as my petcock has been giving me some trouble lately.

    The valve surface where x-ring rides is 32mm. The inner bore of the petcock where the x-ring contacts is 35mm.

    A couple photos are attached.
