should i 1) buy a whole jet kit?
2) buy the jets i need?
any sugestions for the individual jets? i have a FMF Powercore 4, FMF highflow pipe,k&n, and todays hopefully a open air box

 

anyone?

 

Which K&N do you have? A drop in or one with a adapter/plate like a pro-flow? With a drop in you have to use the lid and just cut holes in it. The Pro-flow you can remove the lid altogether which works a lot better than just cutting holes in the lid.

 

i am making my drop-in a pro flow so i can run without my lid

 

better off getting the jet kit, get a GYT-R. the Jet kit comes with jets from 145-165, (2) 25 Piolit jets, and 2 Tampered needles. the new needles make the midrange hit harder and make a smoother transaction from the piolit circut to the needle to the main..
