Thanks for the info.
Not sure whether to take a chance and buy a Zodiac primary or try and find an OEM, I don't want to
have the same problem, as aesthetically it looks awful.

That inner primary is OEM and used for 1983-1984 FLH models. It is a 9-hole primary. Just below the casting numer (behind the top edge of the chain, there should be a date code as well

1984 inner primary pic with a date code of July 11, 1983.

Thanks very much, I'll have a look tomorrow.
Thanks for the info.
Such a shame it's not a great fit.
I think I'll try and find an earlier version.
Should fit better?

I have a 1984 FXEF with a good fitting factory primary. There are a few variations of inner primarys in 1984. Mine is for front and rear chain with a wet (diaphragm) clutch. 1983 and 1984 have a lot of issues like that, belts, chain, dry and wet clutch.

If you are chain and chain with a dry clutch an earlier one should work, As stated earlier there are 8 and 9 bolt primarys too. Do some research before you jump. Post some pics of your driveline.

lovely bike m8, can't really zoom in enough though.
Any chance you could take a closer picture, maybe with a rule, so I can see the difference, as I did?

Difficult to see with black on black, but looks like a better fit than mine.
Thanks for sharing, and once again you have a lovely bike.

Someone above had suggested your primary was for a belt application. This is a Sturgis FXB which is the primary belt drive as well as final belt drive. (Twin Belt) Ive owned 6 Harleys and still have 3. I have never seen the significant step you show in your initial picture. I have seen inner primary chrome covers that are placed on top of the inner primary outer surface. Those dont always fit well and they are like a tin shield over the outside. Is it possible you have a chrome beauty cover over your inner primary?
