i have an 07 450r with the k&n high flow lid and filter and was hoping that someone knew the proper jetting to make her scream again! thanks

 

Big mistake! K&N's pass dirt...I learned this lesson the hard way! The least little bit of grit will toast your valves in no time.....

I run the EHS Racing lid with Outerwears, and the ProDesign (ProFlow) adapter and foam filter (made by UNI).
