The first thing I do is set the sled up properly. I adjust the suspension and track so that is there is hardly any friction at all. Loosen the track, check the belt deflection, align the clutches, clean and calibrate the carbs, check the float bowls, adjust the idle, align the skis, align the hood, and add synthetic grease high and low temp to all the wheel bearings, and grease all the zerks. Then I ride it and get used to it, let the motor break in and clutch it. This would be all the first year of riding.
