I am a new 85 XP owner with questions!!

I recently bought a 2011 850 XP, so far it’s been GREAT!!!! However the machine makes a few noises that I am not use to and hope they are normal for the BEAST. At a very slow roll with the rpms down I here a faint humming noise. When I shut the motor down, the engine stops and for a second or two I here a tic tic tic noise, sounds like when u stick something in a fan and the blades hit it. Its not loud but I am not use to hearing this. :fragez:
