Soon I'll post my mods. I received jets and uni filter from newspeedmaster.com, but they forgot to send me the D-Tool I've bought.
They are sending into an airmail envelope, I hope it arrives fastly, I can't move that fuc%ed screw without the tool.

The Uni has to be openend on the bottom side. It has a plastic wall. Opening the plastic wall of the filter an hole of similar shape and size has to be openend on the bottom of the airbox. You'll obtain another hole similar to the one on the top.

The air the carbs will receive is not far different from the individual K&N pods.
