What size jets should be used on a warrior with a k&n and a dg pipe? Any help I get will eliminate some of the guess and checking. Thanks

'85 350 x
rare '87 200 x(soon to be for sale)

 

Altho you didn't say, I assume you meant the main jet. The stock is a 145. I'd try a 150 first and test ride at full throttle for 3/4 mile to a mile, then pull the plug & read it for proper color. I've heard some negative comments as to the efficiency of the DG pipe, so the 150 may be a little fat. In that event drop to a 147, which should be right on. There is a 147.5 but I never could see that it made any difference either way. It's always better to err on the side of rich than lean to begin with
I have a file photo of my plug which shows the color of a correctly jetted carb, if you think you'd want it. Let me know & I'll e-mail it.
