I have ridden 25% of the time without my hood, so I'm guessing 2200 miles so far.
Usually do between 60-80 miles per ride... Only 6 miles roundtrip on the trail in, so mostly mountain miles breaking trail.
New sled this year, not 1 problem all year (so far, will get a few hundred more miles).
1 belt, changed the diamond drive oil once.
Havent even cleaned and adjusted my powervalves all season.
Over all a GREAT year, and very happy with my sled.
