i just switched over for ski doo this year 2010, i ordered the new nytro 162, and i got a impulse on the way as well. Im just wondering what to watch out for as far as common problems. i was also wondering what happens when u roll these machines does the oil run out of motor if left upside down to long? i spend alot of time chasing my sleds down the hills just wondering if ill have to pack oil with me?
