Depends on how many holes and how big they are........:)

Probably gonna put two 1 1/2" closer to the front of the bike. Unless you would suggest a different set up? Open to ideas. Still learning.

The more big holes the better, jetting for an open air box is #25 pilots, aftermarket needles half way up with 160-165 mikuni mains.............

I'm gonna assume you meant 160/165. Thanks for the help dude. Much appreciated!

make one big hole and pull the lid off. The factory air filter is a bad design so a ProDesign kit is about a must for me. Even if you would chose to run a lid.

I was gonna leave the lid to hold the filter down. Read sOmewhere in the forums that taking off the tube that leads into the airbox allows it to breathe a bit better too? So I'm thinking take that out and can probably nicely space an 8 pack of holes at 1 1/2".

Everything is all done and holy balls! Turns out the valves needed major adjustment as well. Everything all set and done the difference is night and day. No wonder people get addicted to this stuff lol so awesome
