2018 800 SKS 146 GEAR DOWN

[scott agbuis]

Stock gearing is 21/42 70P. Polaris recommends 20/43 70P for high elevation. I want to re-use stock chain and gear down as far as possible. Can I go down to 19/44? Don't care about top speed. Want the best track speed in pow. Any other thoughts?

The service manual says my 2019 850 gearing is 19/40 and 8tooth drivers with a 70p. Interesting stock on the 18 is 21/42.
