Replacement advice needed for '82 1100 OEM air filter element

[willie]

The title says it all. The housing is intact but the foam is crumbling. Just learned via an online parts search that the OEM filter element is NLA. Anyone know of an aftermarket thats still available? Thanks!

Check on ebay... Hi Flo-HFA 3702...appx. $17 & free s/h... K&N made them in the past, but don't see them listed now.

Thanks. If only I was that lucky.
My filter is rectangular.

1100E or 1100G? G maybe? That one is rectangular. Uni sells a replacement if so.

If you need the frame that's more difficult. I believe the later year 850G filter is the same.

THANKS Ed! According to the description, there was only one left.
Should be in my mailbox by the 22nd.
Have a great weekend and a very merry Christmas!

Guess I should have mentioned that my 1100 is a G.

I also have an 82 GS1100G with an aftermarket air filter. It was like that when I bought it recently. For some reason it is wedged in there with a piece of wood. I was wondering if this is a common problem and what anyone has done that is a better idea.

The foam on the cage which helps it seal and wedge into the box deteriorates, and when it does the filter won't fit tightly. Urethane weatherstrip foam from the hardware store should fix it up. Also, make sure the end cap foam is in good shape because air leaks can led to driveability issues.

I've seen the same thing happen on a GK I had quite awhile ago and did the same thing to address it.

I haven't been able to access any dslextreme links that I've found here including this one. I always get an "error 522 connection timeout" error. If someone could post that pdf file here or send it to me I would appreciate it.

Try this one. It shows replacing the foam on the airbox. Replacing the foam on the filter cage is similar. Key thing is to find the right thickness of foam.

That Uni filter works great. I've used it on a couple of bikes. Don't forget to oil it correctly.

Thanks Ed for that link. Is it necessary to seal the covers? As long as the air goes through the filter should be the only concern, right? That's always been a mod to get more air by drilling holes or removing the cover. Also, if you take up the slack using foam, how do you slide it back in without messing up the foam on the cage?

Seal the covers. That way the air intake goes through the snorkle inlet tube, not through gaps in the side cover.
