Fork Seals - Here we go again

[bikerphil]

Only a guess, maybe the 79 Special seal had a double lip and the 80+ was a triple.

[bikerphil]

I don't know the answer to that Marty, I have always wondered the same thing.

Phil,
You may be just the guy to have the answer. Why does the SF seal OEM part number differ from the other Specials?

[bikerphil]

All the Specials use the same fork seal (37X48X10.5) except the 81 MNS which uses the same fork seal as the XJ11 does.

Well, I rolled the dice and ordered the George seals. It says 79-81 specials.

All of the aftermarket seals are specified for all of the Specials. Only the SF had a different OEM part number. I don't have an SF, so I never made a hard copy of the SF parts book. I also wonder why the SF manuals have been taken down.

Surely, others have used aftermarket seals in the SF. Partzilla lists a bunch of them with the '79 on the fitment list. I had to put SG in the search as the SF no longer exists. They're offered in various sizes for the 37 mm tube.

Looking at the list, I wouldn't know what to buy.

If the fork seals for the SF are different than any other then George must be confused as to what fits what ?
Notice he lists the Honda as one of the applications. ??

I see that. Can anyone confirm before I order?

For OEM seals the XS1100SF seals are peculiar to just that bike. For some reason the XS1100SF parts fiche has been removed from the places I look for parts. SF has been removed from the Yamaha site as well.

Does anyone have a recommendation where to get SF seals? Allballs doesn't have any listed that I can see.

The dealer 20 miles from me thought they could order them but then decided they couldn't. The dealer 60 miles from me literally laughed when I said 1979. He claimed the computer doesn't go back that far and told me to "look online."

Any rec's for a company that sells a quality seal and ships quickly?

XJ only

This seal is for an XJ and possibly a MNS only . Sorry for any mixup you had . Nice pics BTW .
