2006 RMK 600 HO Jetting/Clutching

[Eldeno]

Hey new to the forum and looking for some info. I picked up a RMK 600 and am trying to get it ready for some praire riding. We ride around 1000 ft, and temps are -10 to -20 Celcius. I have done the following

SLP AirFlow kit with 2 Flowrites, SLP Can, 65gram MTX weights with no rivets at present and black/pink spring, Team 719 helix @ 66-44-42, and have changed gears to a 23T top and 39T Bottom.

Is this a decent set up for trail, open field, ditch riding. Flat land prairies of Saskatchewan.

What jetting should I be starting with?

should also mention that track has been cut down from 2" to 1.25"

420 main jets should work. That's what I run in my 06 600 rmk in Nebraska with a SLP pipe and silencer.

Thanks. What Gears are you running? What elevation and temps do you ride in?
