Air filter upgrade

[DieselTech]

I recently installed a 49mm steel sleeve 2 stroke on a friends bike, its runs ok, it has nt carb with punisher style air filter. With air filter removed it runs alot better night & day difference. Is this a indication of a over jetted carb or a air restriction due to air filter. Thanks

I cut the upper left and right sides off of mine with a utility knife, simple easy way to let in some air.
