    I change my front sprocket and I now have an oil leak which I presumed was from my pushrod oil seal as this is what people had told me was a common thing.

    I changed the seal and gasket. Still leaking.

    I changed the seal, pushrod and gasket. Leaking worse. 100 mile ride and two drips within a minute of parking up and light film on centre stand.

    I changed the seal for a double lipped seal, new gasket.

    BUT LOOK WHAT I NOTICED . . . . . . . I think this is the culprit. See the two pics. IMG_0302.jpg

    HOLY CRAP

    Look what I found.

    Someone replaced the Sprag Clutch and here's the leak which appeared after I changed the sprockets. I cleaned all the grease and grime off round the clutch push rod etc and that's when my leak started. I modified my casing and fitted it as a trial run . . . . (needs filing up to take the saw marks out) . . . . Started the bike and BOOOOOM there's the leak
