There should be a specific break-in procedure for your sled, check with anyone with a manual. In general though, you are supposed to avoid hard accelerations for the first 100 miles? (not sure on that number, better check it out). You are also supposed to avoid running at a constant RPM for long periods of time. Basically you need to allow your pistons/rings to situate themselves with the cylinder wall, and if you abuse the sled in that time period you screw stuff up.

Correct me if im wrong, thats just what I was told....

First off a search on this topic does wonders.
Secondly you can likely get 10 different answers from 10 different guys on this subject. I have always just heat soaked mine 3 times and then get out there and ride it like you would on any other day. I've done break ins with synthetic and dino oil and found no difference.

Just take for a nice easy trail ride, verying thottle position's & short bursts of wide open. thottle, after a couple of tanks of fuel you will be good to go.
