lol yeah I went down that path like 15 years ago (when the clone motors started coming out everywhere)! Starts with removing the governor, then springs to stop the valve float, then a flywheel (b/c of the "horror stories" out there), then a flat top and 14cc head off a gx160, then a billet rod, then a cam, then bigger valves, . . ...and a few years later, you're sitting there with a bunch of custom one off parts with some behemoth of a welded up billet block with a 4 inch bore, head that has a bigger intake valve than both of the original gx200 valves combined, saying "where t/f all my money went?" ;D
