Topic: 1977 cb750 four f2 supersport oil leak

[dek155]

wonder if anyone can help? she's got an oil leak just where the offside plug is, oil runs down into plug well and along top fins, i can tell it's not low enough to be the head gasket, and not high enough to be the rocker gasket, has anyone got any idea what gaskets gone and is it an easy d.i.y. fix, cheers dek, it's gradualy got worse, and is unridable now as it soaks your right leg with oil below the knee.

have you checked the Speedometer cable?  Sometimes this will get a crack in it and leak oil down on to the head and into the plug area.
