03 rmk 800 jetting reccomendations-- flatlander

[motownmasher]

running an 03 rmk 800 in MN. wondering if any other flatlanders have a jetting setup thats working good. 470's are what polaris reccomends. i'm down to running 450's with needle in stock pos. i think #4pos. seems like there should be more, but a little cautious to jet down any more. stock pipe, aftermarket can. usually running in about 15degree weather.

I think I'm running 450's in my 04' for our elevation. Mine always seems to rip pretty good. Same setup as you stock pipe with aftermarket silencer. No airbox mods.
