Awesome thread, Like the Step by steps.....any Info one should look into as far as changing chain case oil, I like to remove the cover, clean the inside, and inspect chain and gears. Never did too much to a Polaris, have been a Doo guy for the past 30 years
I would change it after a few hundred miles. Since there are magnets on both the fill plug and the drain, nearly all the metal "floaties" are captured. The drain actually drains on a Pro, rather than spooging up the bottom of the fender like an IQ. Put the drain back in and fill with your favorite gear juice. (I use Amsoil tranny fluid but everyone has their favorite, Poo used to use Mobil 1 gear oil but went to something different that turns black after a short time.)
Then "fill to spill".
For those that like to remove their hood: (If you're good, you can use the spark plug tool to remove the Honda clips)
Use a 6mm x 1.00 tap and fully tap the hold down screw holes.
When re-installing the hood:
Set it down on the air intake to line it up and adjust it to the rear to line up the hold down screw holes,
Install the hold down screws most of the way,
go to the front of the hood and inspect to make sure it is lined up side to side then give it one "bap" with your hand to engage the hood to the nosepan.
Finish tightening the screws and pop the Honda clips back in.
If you try to engage the front of the hood and then install the screws, you end up fighting for that last 1/16" to get the screw started. In a warm garage it might work but when it's cold and the hood shrinks a little, you swear a bunch trying to get the g&# da*$ screws started.
YMMV
