Thanks Hilarious, we try!
Dajogejr, motors would get burnt down around here with the jetting specs your saying. Our findings are right inline with Kevins as we are at 1400 ft and run 172-175 range on most w/39s, and at sea level or longer runs we run 180 -185 range. In my experience, if the Drag porting flows efficiently enough it doesnt seem to change jetting on Cubs more than a jet size or 2.
Ryskie22, in the end I recommend you ask whoever you bought the cubs from or your builder as they should know or they shouldnt be selling/installing them because as you see, on the internet you will get several answers and some could cost you alot more money than others!
