Stock Air Filter Wow's
The stock air filter on the Vulcan 900 is very restrictive, as most of you know, so I will likely upgrade to a Baron BAK soon. Even though the bike runs great and gets 50 mpg, I'd lie to improve the breathing. I'm told that the metal screen on the filter blocks 1/3 of the airflow, if that's true what harm is there if the screen is removed (would be like an ordinary filter).
Also, I always thought the bike was factory tuned to run lean, now I'm told that it runs rich so air air filter upgrade should improve combustion without and EFI re-tune, correct??
I welcome any and all feedback.
