2017 M8000 Gear change down?

We ride the Trees a lot and a suggestion has been given about down gearing it abit. Have any of you done this, The Stock gearing seems to be 19 upper 50lower 90pitch 13wide chain.
Thoughts?

I know alot of guys gear them up me included. I think most are running in the 2.3-2.5 range were stock is 2.63. I don't think I've heard of anyone going lower then the stock 19-50

yes gear up 20/50 is a good place even like 20/49 but if you do a lot of long pulls the belt likes the 20/50 better

take a look here https://www.babbittsonline.com/oemparts/c/arctic_cat_snowmobile_2017/parts

M8000s with the SKU numbers ending in 'USB' have 21/49 gearing.
weird.
I thought all 2017s were 21/49 but apparently not.
my buddy has one that seems to pull hard as my mountain cat until it gets stupid steep. his must be 21/49.
anyway I wouldn't go lower than 19/50 with the 7 tooths. kinda giving up your pull when the trees widen out.

8 tooth for the 2.6 track and for the Mtn Cat 3" track and dropped chain case.

My '17 MC 8 tooth, 3" seems geared perfectly. I am a big guy and ride 10,000 feet and up.
