I may need to replace the inner primary. Anyone know what the replacment might be- e.g. stock FXR '89-93? There are no part numbers stamped inside it so not even sure what to look for. There seems to be several different HD part numbers for the older FXR primaries, so it's not clear what fits what.

It's a stock Harley Primary - 1-7/16th offest I believe. There should be some stampings on the inside of case confirming the offset. Picture just isn't clear enough to see.

Although wtf is wrong with this one? It doesn't look bad from the pics unless I am missing something?

Heres one on Ebay now:

the casting is poorly done and cannot read the stamp number. There is a bit of worn lip on the edge of primary that meets the engine case. This lip actually wore a .020 step into the engine case so now I have to get the case machined flat in this area.

I may be able to just smooth the lip and re-chrome, but if not, then need to pick up another one. or go with an open primary. but again, no idea which one to get / what will fit.

There are two or three type of FXR primaries- early, mid / late FXR. I think the early was also the same as the FLT primary. Really have no damn idea. Per Baker, there is supposed to be no offset whatsoever.

I'm trying to look up primary gasket kits and there are literally three different kits depending on year. but they all look very similar. really a head scratcher. I can say for sure it is not the 15-0865 kit though.

I've identified it as a Delkron primary that has been chromed. I'm waiting for my mechanic to measure the starter jack shaft hole to know what year range it is. older models had the bigger starter gear and larger hole, newer (94 onwards) had the smaller starter shaft / gear. but the hole diff is very minor so can't really eyeball it from the photos.

Update- This inner primary is specifically 84-93 FXR. The 94-06 FXR gasket will not fit due to different bolt hole locations (I actually compared both types of gaskets side by side). Drag Specialties, James, Cometic all provide gaskets for the 84-93 range. It may also be specified as "85-93" FXR but that is still correct.
