Revolution Performance Milwaukee 8 Velocity Cylinder Head Package

(For Milwaukee 8 engine style motorcycles)

$1,839.95

The Revolution Performance Milwaukee 8 Velocity CNC Cylinder Head Package has been painstakingly developed on the flow bench, dyno and street to increase power and torque on 124" and 128" Milwaukee 8 engines. The new Milwaukee 8 4-Valve head has tons of potential, but is extremely restrictive as stock. We have developed our Milwaukee 8 CNC Velocity Head Package to get the most out of our 124” and 128" Bolt-On Big Bore Kit. The ports are machined with laser accuracy on our state of the art Centroid A560 5-Axis CNC Machine Center and then hand blended. We install new guides and the seats are CNC machined on our Newen BB Contour Turning Center. The combustion chamber is polished and the gasket surface decked for optimal combustion chamber volume. New custom oversized intake and custom oversized exhaust valves are installed with .535 max lift valve springs. The head is shipped ready to install.

    Included in each Velocity package:

  • CNC port work
  • New custom made oversized intake valves
  • New custom made oversized exhaust valves
  • New .550 max lift springs
  • CNC valve job with new exhaust seats and guides
  • New valve guide seals
