HI fellow aviators. I'm very interested in hearing about the experience and expertise of those who have worked with the BMW R100 conversion recently. I say recently, because I understand that there's a new upgrade from Siebenrock bringing to reality 85 hp at affordable pricing - without requiring machine work. I this track very attractive especially when considering the alternatives, i.e ROTAX 912si, and Jabiru 2200. Asking the group to give be some opinion. I think the powerplant package weighs near 155 lbs.... not so bad.
