I have a 2000 banshee with T-5's and K&N's with no airbox, wiesco's and i'm currently running a 300 main, when i install the 4 degree key am i going to have to change my jetting? If so anyone know about how much bigger? Thanks for the help.

 

you wont need to chenge your jets just from a degree key, if it is jetted right before the key then it will still be good.
