Need details. What exhaust? Jet sizes? What air filter? Carb boots on tight?

It's probably the K&N.

Ditch the K&Ns.

Tune to stock, then add mods.

The first thing I would do is pull the K&N and see if the flat spot goes away

one how do i check the float hight and what is speck. i will find out what jets i have i dont know what the stock jets are and the needles are set to full leen so the needle clip is as far to the top as it can go and if any one knows of a good link on how to check katana floats that would be cool
