ok, well my old 400 is leaking oil from somewhere. im thinking its the seal where the clutch rod goes in to the case. or it might be a copper ring for a banjo fitting. the fittings are tight so im thinking that is the seal but i cannt get it to leak unless im riding but then it gets all over and i cannt tell.

anyways if theres any common stuff id like to hear about it

anytime you remove the banjo fittings for whatever reason, replace the copper washers. They only seem to seal properly one time.
