[replyingto=oldchopperguy]oldchopperguy[/replyingto]Thanks, Leo! That's very informative. 
Yeah, like I said with my UNI filter it seemed to run fine, just had popping and lean conditions with my small jet so I put an actual sock over it to restrict the airflow some. Problem (temporarily) solved! Or so I thought... I understand your post a lot better now that I know the proper term for the foam filter "sock". ;D
After a long trip to pay the water bill, go to ace hardware, and stopping at a few other places I got home and wondered why my lean conditions had returned, but gave it no second thought because I knew my jets would arrive later. When I took off my seat bucket to replace my intake manifold I finally noticed my filter had been gone; for how long I do not know.
If it weren't for the risk of micro abrasions on the cylinder wall I'd just up jet to 98 and run without any filter at all. But I know that's a bad idea.
I've never ran my scooter with a stock filter before because when I had the stock filter installed it was broken beyond repair to begin with. So I technically never have used a properly functional stock air box. I hear that any tubing between the intake and the air is restrictive so I'd prefer to not even bother with it and stick with the so-called "performance" filters.
