Ran my new to me rzr (’13 xp4900 w/ alba stage II kit) for the first time this last weekend. On both days my buddy who was trailing me said he could smell and see a very small amount of smoke for the first 1/2 mile or so and then it went away. I had just changed the oil and cleaned / oiled my filter and oil level remained fine throughout the weekend. This only happened when the rzr was cold, first fired up in the morning, and for the first small portion of the ride. Day 1 I ran 50 miles and day 2 I ran 40 miles with absolutely no smoke or problems after that first 1/2 mile or so. Is this common when these are cold? Is this something I should worry about?
