This is true. Polaris only "roughly" machines the gears. It relies upon them actually running against each other to do the "final" machining to get them nice and smooth. That's all those particles you get from the first oil change. My first one at 1500 miles shown up almost iridescent due to all the metal particles. The 2nd oil change (5K miles) they were barely noticeable. By the 10K oil change, they were gone. So Drive, and Change Oil at the beginning.
