2007 grizzly 700 rough idle to wont idle

Hey everyone I need help figuring out what is wrong with my grizzly.
2007 grizzly 700
734 big bore with 5mm stoker crank making it like a 778 or so I believe.
I have a dyno jet pcv with auto tune on it.
stock exhaust.
stock airbox with extra venting put in it and uni filter.
stock cam

So it runs great just doesnt idle for crap.

I just took out the throttle body and cleaned it and took apart the idle control valve thing and didn’t see anything weird. Not sure how that thing is supposed to work.
I also re adjusted my valves they were a little tight I set them to the loose end of the spec. still wont idle.
Please help
Jim
