What Is Drone

[88Racing]

The DIY intake mod allows for more air at higher rpms. As long as you don't modify the OEM tube and take off the silencers there should be no droning noise some have done this and reported some noise when silencers were removed.
For $8-$15 the cost and effort is minimal compared to an aftermarket CAI and the gains you would get with that.

I'll add to Lars' reply -

I did the mod, I think I've gotten improved performance (I'm sure it's helped my fuel economy, maybe by at least 0.5mpg), and there's NO drone. I didn't cut off the resonators.

As Lars mentioned, it cost me less than $10.

so much for the good ol days when the air cleaner sat right on top of the engine and carb... it wasn't even and issue back then.....
I would try lining the intake with a sheet of rubber or some spray on liquid electrical tape , closed cell foam or something like that and see if it helps eliminate the drone. Something to dampen/absorb the vibration

Hard to believe that was you, buddy! I have a picture from "way back when" too, I look so "wet behind the ears" - and I was in the cockpit of an Air Force fighter!

I guess, if we survive those years, we may possibly turn out to be worth something!

Let me guess?
You lost the wing nut and your holding the cover down while you are adjusting the carb or the timing?
J/K!
Oh our younger years!
