06 Pred 500 jetting?????

[12manytoys]

Im having problems jetting my 06 pred 500. It has a Pro Circuit t4 slip on and a K&N drop in. Right now im at a 167.5 main adn it still has a slight miss on top end. Its not the rev limiter because its not a consistant studder and its not revving out like it should. Any help would be great.
