Default Air filter shouldered screw

Anyone ever replace the shouldered screw that mounts the air filter to the backing plate on a late evo? Part #893A, obsolete (like so many things)..
Short of some custom lathe work i cant find an easy replacement. Maybe a modern air cleaner is in my future. If i can find one to fit a Magneti Marelli intake.

I never have but they list them here. I think they only ship UPS so that adds a lot to the cost for small orders. At least it's a start....

Are you talking about the four bolts that go into the throttle body? Because....

OEM factory used one type

SE EVO used regular Allen bolts of two different sizes.

SE on the Twin Cam used four bolts that mount to throttle body, then four screws screw into those bolts that hold down the air filter.

Got a picture of what you need?

My bike (98 FI RKC) had stage one air cleaner and pipes on it when I bought it. It uses a different set of screws. You could scare up a stage one kit for it and get a reusable K&N air filter in the process.

I understand that you are on the hunt for an obsolete part. If you post the part number in this thread, I'll see if I can locate some for you

Having a hard time getting my head around where this goes, but it looks like 1/4 bolt with steel sleeve slid over it would be a temporary fix, especially if not visible.

Ebay or dealer search (any dealer parts guy can do a nationwide search) would be my next choice. YD

It is one of two shouldered allens that go through the air cleaner, like the one in the post above, thanks all

That is an interesting suggestion. The sleeve would slide inside the air filter and stop the bolt from crushing the filter. I may experiment with this when i get back to o

hio. Thanks
