I picked up my 2002 700xcsp last night! My first new sled. What do I have to do to break this thing in? Its black, looks sweet. My wife made me get the extended warranty. Are they worth the money? 600 for extra 3 years. I got the sled for 5700 so I still came out alright. Also can I change the cluching and jetting without voiding the warranty? What about the TPS?
