I am interested in buying a kitfox in the future and have noticed some autoconversions such as the Honda cam 100 hp on some of them. I know the lower hp Subaru is just too heavy to be considered. I am curious to know opinions on hp to weight differences between the rotax 912 ul 80hp and the 100 hp conversions. The conversions obviously weigh 100+ pounds more but I am wondering if the hp difference in the two motors will be about equal in performance with the weight differences. I am wanting the performance of the 80hp rotax is why I am asking and am worried about the weight of the conversions hindering performance.
