I have 2000 warrior e series exhaust kn filter cover off filter box I jetted carburater with dyna jet kit but I can not run the 150 main jet because it skips at high rpms what main jet should I use it runs good with 144dj but the stock is 146.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Stock and DJ jets are different, the numbers don't match up. So go buy how the plug looks and not the numbers, the DJ needle is shaped different.
