My buddy has the exact same sled as I do, but one year older. Sometimes on the trailer they dont sit at the same height either. His is always lower than mine, but he also wieght 100lbs more than I do.
I always thought it was strange, but always attributed the difference to wieght. we have the same Ohlins EC rear mono with the same spring (factory). He should definately have the bigger spring in his though.
