Default HELP!! Jetting w full SPARKS and K&N (raptor)??

I am going to be getting my full Sparks X6 exhaust along with a pro flow adapter with a K&N (with outerwear) in a few weeks now. I am just curious what I should run for jetting (mains, pilots, air screw mixture, needle slot) with a GYTR Jet Kit. I ride at anywhere from 400 ft above sea level to 1200 ft above sea level. I will be trimming the snorkel flaps and drilling 2-2" holes in the most rearward side of the air box lid. Thanks alot...

I'm thinking you should start off somewhere around 160-165...

hey six, does one mixture screw have to have a bit more out than the other? I have my both screws at 2 1/2 turns out. Which one has to be screwed out more?

Make sure your floats are on point if you don't know how then try and learn how to adjust them cause I have the same exact setup except I have a foam filter. I attempted to jet my raptor and I had the correct sizes, turns everything but my floats were out and bike ran like crap so I took it to the dealer and they said the floats were off. I looked at all the post on adjusting the floats but I just couldn't get it and don't have enough patience for trial and error. Now my girl runs STRONG!

You probably don't have to have them set different. Take another look at my last post.

RAPTER is right about the float level.
