After calling BRP and getting no where, I finally figured it out. The 2006 Utopia 205 Edition 1 has engine configuration A. The second edition has engine configuration B.
The different configs are easy to recognize if you look in the intro section of the shop manual.
The easiest way to spot the difference is to look at the oil fill tube. If it looks like a long straight plastic tube then you have configuration B (Edition 2). If the oil fill is metal and short then you have the A variant (Edition 1)
