Maybe there is only enough vacuum pressure in the hose at certain rpms and that is when i can hear the rattle.

Try a zip tie - a nothing job and then you'll know.

I like disabling the flap, but don't find the note very pleasing, vs, say, the sweet sound of a 60's Triumph bike. Othern' that, disabled flap is very good indeed.
