Hi has anyone have a pdf file or paper copy of engine parts for a type 54 engine 77 250 gs. After some small parts and need numbers for them.Or a site where I might find such info.Who in Aust has any parts for these engines,or does most bits come from that al bruerner guy in the states? Need one fancy nut with shoulder for clutch the ones that the little split pins go through.Primary drive key,or a model that matchs.I bought a gasket kit for it but the base gaskets are slightly different ie square r ,my cases are more rounder and flowing is there a difference between years or models. what is correct part no for gasket set. Cheers ELC hunter.
