Just got back from a ride, we're at minus 30 with the windchill, got my sled up to 112mph bofore I ran out of room! The sled rocks in this cold, I'm sure I'd hit 116-118 with a little more room!! I've finally put fresh gas in it, no mixture and let her go after 250 miles, quite impressed compared to my 05 F7 SP!! Only mods I've done are the ones everyone says not to do, air intake and a speedwerx silencer....and no it's not LOUD!!!
