A kit made in the U.S. could not compete on price. But could certainly be of better grade components, materials and manufacturing tolerances. But would it be worth paying more, for? Using a base price for a 2 stroke, China Gurl at $150. I am thinking of expanding my machine shop to have the ability to produce engines. It's a lot, and I mean a lot of money. It's such a small market dunno if it would be worth it. I really like the tinkering and making parts but this would be a huge endeavor.
