Gearing for 2013 SBA? What to try other than stock

[SwitchyD]

I've got a new 13' SBA and want to try some new gearing.
I really don't care too much about top speed as long as I could still pull into the 90's. The sled launches well as it sits but my buddy with a 13 XF 800 took me off the line and I'd like to fix that haha.
I'm really looking for more out of the gate and a hard midrange pull not top end.
I believe stock gearing is 23/39???
There is much more knowledge on here than I have so let me know what you guys would try.
I am at sea level elevation and use the sled as 50/50 on off trail with the accasional 1/4 to 1/2 mile drag with my buddies

Look into the switchback gearing to match the Stock RMK gearing. Can't remember what it is but it's what i used in my 11. Worked very well

gear

I ran a 22 tooth upper on My 11, and it still ran down the lake at 103. I am doing the same change to my 13. Still ran the stock chain, and put 1000+ miles on it with this set up. The only flaw, is that in some snow conditions it would hit the over rev with the 1.35 track spinning wildly on ice or really really really fluffy loose snow. Not really that big of a deal, and corner to corner it ripped.
