I'm looking at buying a 03 800 rmk for 2500 and it has 3000 on the chasis and 500 on total rebuild of topend and crank with big bearing kit, and the guy has the receipts to prove it. i was just wondering if that would solve all the crank issues known to happen with the 800's??? and the track is a 159" and i live in iowa, and i was wondering how hard it would be to turn and how much snow i could ride it in without beatin up the track?? it also has reverse, simmons skis, v force reeds, and some other stuff. any info would help
