I just picked up my RTV 400 today. I havn't had much time to use it, but I did manage to put about an hour on it. Being that this is my first side by side, I have a couple questions that I was hoping to get answered.

1) On acceleration for the first 50 feet or so it feels like the back tires are out of balance and then it smooths out. Is this common, or is it something with the belt drives?

2) Also the service manual suggests that oil and trans fluid be changed after first 50 hrs, is that the norm, I know it is with the oil but I don't recall changing the tranny fluid on the first 50.
