Anyone done a K&N drop in filter, plus rejet, and have their old restrictor ring laying around?
Methinks I need one :-/

You can make your own.
It is just a donut about 1/8" thick as you can see.
Buy a roll of sticky back neoprene pipe wrap insulation (as shown) and cut a strip 1/2" wide and stick it around the inside hole of the air filter.
Same effect - makes hole smaller to restrict the air.

lol.  I'd be too worried that it would eventally fall in

Post 1000,..yeaaaa,...

I have mine sir,...just lying around on the shelf in el garaje,...want it?

put a sock in it.
No, literally ...
Cool.
Buddha.

If you do get the restrictor, be sure to secure it to the filter.  Mine kept falling off and hiding behind the battery.

It is sticky back. If it fell  in, it would fall INSIDE the air filter and do nothing other than allow a little more air in.
Same thing - cut a circle in a big flat piece and stick it on the top.
Anything to reduce air flow will work. A sock, old jock, used bra, holy underwear, your hand.....

Make an adjustable air restrictor!
