I have 2016 Pro S 800 Switchback studded with 1.352 cobra. I would like to gear to 1.73 or 1.74 as recommended here. The service manual I have says stock gears are 23/37 . I am sure I have read here or on other forums that the top sprocket "stock" is a 22 tooth. Can someone verify this for me? I would like to buy the parts and have them ready to change over as soon as I take the chain case apart. Great forum here. Lots of very helpful stuff.
