So today I did my break in service on my 2015 grizzly 700. Changed motor oil, front diff and final drive. Filled final drive as the manual stated. Fill through the fill plug with check plug out. Waited until oil began coming out check plug. I took it for a ride and upon returning to the house I noticed that the final drive seemed hot. I never noticed it before but it may have been because I was checking over everything today since I just changed the fluids. It was a 16 mile drive total with various speeds. I did some searching online and found that it seems common but wanted some other input.
