Restricted Free Flow?

[lykos23]

So last month my scooter was having problems with dying at idle, or not coming down from idle, leaving me shaking and vibrating like crazy at stops. No matter what I did to adjust the idle and a/f it kept having this problem. So I called up my local motorcycle shop and asked them how much it would cost to fix this. He said "bring me a 6-pack of pepsi", so I bought a twelve pack. Once I got my scooter to the shop, the guy is all "where the hell is the airbox?" and I was all "it was broken, so I put a freeflow on it", and he argued that the airbox has to restrict the airflow or you get the problems I'm complaining about, etc.

So, in five or so minutes he yanked my airfilter off, taped the hell out of it, then put it back on, adjusted the a/f, then the idle. Ever since then my idle has been fine, my scooter never dies at stops anymore, and the whole thing sounds different. I've got no real complaints, but I'm wondering if it is really my best option

Is it really all that good to have a restricted air filter? For instance; would I get more power out of my scooter if I upjetted my idle and removed the restriction? My main jet is 85, my idle is stock.

Here is a picture of what was done in case you want to try this for yourself:

I think he used electrical tape, but it was extra wide.


Edit:
Is it worth the $10 to order a new idle jet?

And is this idle jet bigger than stock? I can't find the measurements
