I think cylinder porting from Ly-Con in Visalia is the best deal yet. They are and FAA approved repair station, and the porting is approved. For 200 dollars per cylinder they will smooth up your ports and rework the valve seats to a 3 - step seat. No STC or expensive crank to purchase- what you get is 5 HP per cylinder, so from a C-85 you get 105 HP, and you get increased fuel economy, not lessened. You only have to re-pitch your prop to handle the increase in HP. Re-pitching is about 250 dollars.
