BAHNST I can say that because I recently finished a total restoration of one. Yes it was interesting but the depth of the build and the lack of certain OEM parts due to its limited run made it a major PITA.
Yes I had a parts guy tell me that this bike uses parts and pieces from other models. Almost like they had something they wanted to try so why not just throw it on this odd man out machine. In hindsight I do remember looking at that seal and I actually have it in the drawer I was just reluctant...
Yes AMC49 that is the only difference. I totally missed that inner on the diagram(I think) and I see it is still available. I wisely ordered two of the outer I found I think the issue is I have to split the case to get the inner out.
I am also looking for the countershaft oil seal. The part # is 91203-393-003. It lists as a 32x64x13. I found a 32x64x10 that I replaced it with but I’m seeing oil leaking out when I run the engine and I’m highly suspect of that being the culprit. Anyone know where to possibly get this NLA seal?
