05 rm85 cutting out up top
 

hey guys im new here i just got this bike on trade and trying to figure it out. its an 05 rm85. starts easy idles great weather hot or cold, cold compression is 150. dropped exhaust pipe to look at top end and it looks great no scratches or signs of worn top end, plus idles great when warm. Problem is about 10-15 minutes after riding it seems to cut out high in the rpms. i have the needle on the second groove 125 main and 45 pilot air screw is 1 and 3/4 out new njk bpr10es, and it has some plastick reeds idk what brand. im thinking stator but need a second opinion before i just throw parts at it.
