can you push them back with your finger? Can you retract them when blowing in the Fat vac hoses which attach to the sub filter

yes, that all works well but when bikes started, in neutral they open a little up to 7000rpm then the bike wants to die

Thats your problem then, these bikes dont like to be messed with, with the airbox lid etc off, your making it LEAN hence why its dieing.

Your like ersan youve been on about your carbs for months, and to date i dont believe any info has been listened too.

Leave the things alone and let someone work on them know what there doing.

Please don't use anything but a genuine honda air filter, it just opens up a can of worms when it comes to jetting and midrange driveability usually suffers.
Okay, thanks! Saves a bit of money, too. Haha what about a 10% increased volume airbox? And would/should I do the bit you said that improves the midrange power/responsiveness? (I can't remember it and am on my phone posting this, otherwise I'd find the exact part.)
