Abstract: A method of modifying a hub with a wheel adaptor. The wheel adaptor includes a cylindrical body, a first set of holes that includes six symmetrically spaced holes located at a first radial distance, a second set of holes that include three holes located at a second radial distance, and a third set of holes that include another three holes located at a third radial distance. The method includes coupling the wheel adaptor to the hub. The coupling includes passing six symmetrically spaced lugs of the hub through the wheel adaptor at the first set of holes and fastening using six hub lug nuts. The method further includes drilling six holes through the hub using the second set of holes and the third set of holes of the wheel adaptor as drilling guides.

Abstract: A system and method for a combustion engine having an engine block with a V-shape, where eight cylinder passages form two banks of four passages. Each cylinder passage receives a piston from a set of pistons coupled to a crankshaft. Seven ignition devices couple to seven of the eight cylinder passages. Every 102.85 to 102.86 degrees of rotation of the crankshaft, one of the seven ignition devices trigger combustion.

Abstract: A system for adapting a hub for coupling the hub to a wheel where the wheel is not sized for attachment to the hub. The system includes and an adaptor or wheel adaptor for coupling the hub to the wheel. The wheel adaptor includes a body, a first set of holes, a second set of holes, and a third set of holes.
