  • Type of engine. The engine type, such as a V-Twin or Big Twin engine, can affect the rebuild cost. Big Twin engines are typically more expensive to rebuild than smaller V-Twin engines.
  • Parts. The cost of replacement parts, such as pistons, camshafts, and bearings, can greatly affect the total cost of the rebuild. The cost of parts can range from a few hundred dollars to several thousand dollars, depending on the type and quality of the parts.
  • Labor. The cost of labor can vary greatly depending on the location of the shop and the experience of the mechanic. On average, labor costs for a Harley engine rebuild can range from $75 to $150 per hour.
