How to Take a Motorcycle Engine out of the Frame

The typical motorcycle engine removal procedure involves the following steps:

  • Drain the oil completely.
  • Disconnect or remove the battery.
  • Remove the gas tank, ignition coils, spark plug wires.
  • Disconnect electronic ignition or points.
  • Disconnect all hoses connected to the engine.
  • Loosen and disconnect the clutch cable.
  • Remove the airbox and carburetors.
  • Loosen and remove the exhaust headers.
  • Remove the shift lever, brake lever, and foot pegs on some bikes.
  • Begin removing the engine mounting bolts, keep track of where the go and how they’re assembled.
  • Remove the last mounting bolt and you’re ready to remove the engine.

The engine will typically need to be removed and installed from one side of the frame – usually the opposite side of the engine mounts that are welded to the frame.

You may need to angle it slightly as you lift the engine out and over the frame tubes. On some motorcycles, it is easier to lay the bike on its side and lift the frame over the engine.

If you do that, be sure to place some wood blocks under the engine to support it.

It can definitely help to have an extra pair of hands when removing the engine from the frame.

When you’re ready to install the engine back in the frame, follow the reverse order of disassembly.

Refer to your motorcycle’s shop manual for the exact instruction and engine installation and removal steps.
