Abstract
A V-2 engine; with four valves per cylinder, dual overhead camshafts, offset cylinders, and a single crankpin crankshaft; that will fit onto the stock front and rear EVO crankcase mounts, the stock primary drive and crankshaft mounting locations, and within the frame rails of a stock size EVO chassis (whether OEM or aftermarket).
Claims7
A V-2 engine comprising:
- a crankcase;
- a crankshaft rotatably supported in the crankcase, the crankshaft defining a longitudinal axis;
- one crankpin disposed on the crankshaft at a position spaced apart from the longitudinal axis;
- two cylinder blocks each having a cylinder head, the cylinder blocks mounted to the crankcase such that the cylinder blocks are arranged at an angle to each other, the cylinder blocks being offset from each other along the longitudinal axis such that a first connecting rod in the first cylinder block and a second connecting rod in the second cylinder block are capable of being connected in side-by-side fashion to the one crankpin, the engine being air-cooled by fins located on the cylinder head and cylinder blocks;
- four valve mechanisms mounted to each cylinder head;
- two camshafts mounted to the cylinder head of each cylinder block;
- a power transmitting mechanism for transmitting rotational power from the crankshaft to the camshafts to drive the valve mechanisms;
- and,
- wherein the crankcase fits onto stock front and rear EVO crankcase mounts and the crankcase mates with stock EVO primary drive and crankshaft mounts.

A V-2 engine, comprising:
- an air-cooled crankcase;
- a crankshaft rotatably supported in the crankcase, the crankshaft defining a longitudinal axis;
- two crankshaft journals disposed on the crankshaft at a position spaced apart from the longitudinal axis;
- two cylinder blocks each having a cylinder head, the cylinder blocks mounted to the crankcase such that the cylinder blocks are arranged at an angle to each other, the cylinder blocks being offset from each other along the longitudinal axis such that a first connecting rod in the first cylinder block and a second connecting rod in the second cylinder block are capable of being connected in side-by-side fashion to the two crankshaft journals;
- four valve mechanisms mounted to each cylinder head, the four valve mechanisms including two intake valves and two exhaust valves;
- two camshafts mounted to the cylinder head of each cylinder block;
- a power transmitting mechanism for transmitting rotational power from the crankshaft to the camshafts to drive the valve mechanisms;
- and,
- wherein the crankcase fits onto stock front and rear EVO crankcase mounts and the crankcase mates with stock EVO primary drive and crankshaft mounts.
