2016 850 SP belt/gear whine

Hey guys! I bought a new 850 sp in January and it’s awesome! Love the machine so far! The only thing I’m concerned about is it has recently developed a belt or gear whine. It does it in low and high range. Seems to be in the same rpm range in both ranges. Sometimes i can feel something rough in the drivetrain. I noticed the whine slightly when i was riding in Wisconsin in July. I didn’t have a chance to do anything besides service it before i went to West Virginia the first week of August. All fluid levels are good and it got quite a bit worse in West Virginia. It is almost unbearable at times. I am planning on taking to a dealer after Labor Day beings i have extended warranty on it. It has just a touch over 500 miles on it now. Just curious if anyone on here has the same issues or any information on it. Thanks for any help in advance!
