  • over 200 parts, approximately 3 hours build time, assemblky with screws (no glue!)
  • functional crank shaft, pistons, LED tipped sparkplugs, cams, valves, and 5 speed transmission.
  • clear cylinders and crankcase let you watch all functional parts driven by the included electric motor; the spark plugs light in sequence, and a sound recording of the real engine starts and revs
  • a gorgeous color photo book chronicles the history of this famous engine and the motorcycles it powered, and concludes with the clear and detailed assembly manual
  • I recently built the Porsche Four Cam racing engine by the same manufacturer and was impressed by the quality and assembly.
