Air Filter w/Screen leakage? TE310

Looking to get some input from both sides here, those who use, and those who don't use the back-fire screen with thier air-filters. It would seem I'm having a hard time getting a "perfect" seal using the screen, as this is the 2nd time I've found small traces of dust inside the air boot when using it. I oil my filters properly (same way I have for 20 years), grease the seal on the filter, and run a thin bead between the air boot and screen. I fit it, run my hand around to insure what appears to be a tight fit, yet still getting a small leak somewhere. Filters are new twin-air, Oil is No-Toil. Used it since it came out 10+ years ago and never had any issues. Going to go back to running without the screen and take my chances, but wondered if anyone else has had similar results, or it's just user error somewhere along the line.

Twin Air sells a special filter that don´t get fire and is exactly for this issue.

I took out the backfire screen. Never had is back fire yet.

Use twin air backfire filter. Backfire filters include a laminated layer of backfire-retardant foam.

if you guys are taking the screen out im going to do the same. after i took it out to clean it once, it never stayed flat again

Took mine out 2 years ago. Not so much for the sealing (not great anyway) but for aspiration.

I took mine out 2 years ago too and alternated between 2 Twin air filters with no backfire problems. I now have a K&N filter and have no problem with it either. 2008 TE310

I also felt I got a better seal w/o the screen. Ive gotten "stuff" in the air boot with or without, but far less without the screen.

My bike came from the dealer fully de-restricted and powered up, also that screen was never installed and i've never had a problem.
