2012 polaris pro rmk 800 155" ANY ISSUES!?

in the fall i sold my 2010 polaris assault 800 rmk 146". and bought a 2012 pro rmk 800 155". Just wondering if anyone is havin problems with this sled, its got 500 miles on it now and still going strong. previous owner put 480 miles on in mountains, so its still clutched for mountains. What should i go with for color of spring and weights for saskatchewan riding? Thanks!!

Leave the stock spring in it if thats what it has. The sleds sold in sask comes with 2 sets of weights, 62g (mountain) and 68g (flatland). All we do when heading to the mountains is swap weights, everything else seems to work quite well... As for the rest of the machine, I've got a 2011 RMK Assault with 3600kms on it, not a hitch. Let the sucker warm up for a while before you crack it open, then have fun. I usually see 85-100 degrees Farenheit before moving the sled. Running I usually see 123-127 here in the flatland, don't remember what it was running in the mountains, but hope to be heading there soon to find out.

Where the hell are mountains in saskabush?

It was in revelstoke before I bought it.
