Have 2004 1M 900 EFI 159".
The sled does everything I want it to do. Handles the deep snow well and have not had any mechanical problems with it. During really cold mornings it can be a bear to start. Only option at times is to remove plugs to turn over a couple of times and then will start. Must get that motor to turn over for the battery less system to charge up to start. I was told a little WD 40 in each hole when BDC would help in starting. Have not tried it. I was told this is better then starting fluid that I used once. Starting fluid is to explosive and can cause damage to engine. I got a chance to ride a new style Polaris 600 RMK and really liked the ease of turning. Turns quicker then my 900 but the power isn't anywhere close in my opinion. I don't have to take a run at a hill to get up it. The newer chassis style maybe the way to go but still happy with my sled. IM is a time tested bullet proof sled in my opinion.
