    Help: GS425 oil leak

    The oil leak in the picture has been getting worse . I'm not 100% sure but I think the oil level hasn't gone down.
    What would be the easiest fix?

    Wow, that picture is hard to diciphire...

    It appears that that leak could be coming from your sprocket area. I'd remove the sprocket cover and see what ya got. My bet is it's gonna be the shaft that run's into your crank case.. There's an oring there that's prone to leaking...

        Both our 450's were leaking from the shifter seal. The E was dribbling pretty bad so I replaced it. Once I have the countershaft sprocket cover off again I'll replace the seal on the S.

        If it is the shifter shaft seal, its pretty easy to fix. I think my coutershaft seal is staring to leak too... D'oh

          Could also be the clutch pushrod seal

            450 oil leak

            There are three sealed shafts under that left side cover: drive shaft, shift shaft, and clutch pushrod.

            The drive shaft is the most comon to leak. There are actually two seals here, an inner and an outer. You could probably get by with just replacing the outerseal, though since you only want to do this once...

            One of those two seals can be ordered with a metal "flange". Make sure not to order the "flange" type as instalation requires splitting the cases.

            Clean the clutch pushrod while you are in there. I think its the dirt on the pushrod going in and out of the seal that makes that one leak.

              Not sure, that looks like a nice aftermarket feature... "automatic chain oiler"

              Where can I get one?

                LOL
                I think most GSs come with it. Maybe it was invented by Triumph, BSA or Norton:-D !
