To change the spark plug on a BMW Isetta:

1. Ensure the engine is cool.
2. Locate the spark plug on the engine.
3. Disconnect the spark plug wire.
4. Use a spark plug socket and ratchet to remove the old spark plug.
5. Check the gap on the new spark plug and adjust if necessary.
6. Install the new spark plug by hand to avoid cross-threading, then tighten with the socket.
7. Reconnect the spark plug wire.

Replace spark plugs every 20,000 to 60,000 miles, as worn plugs can cause misfires, power loss, and increased fuel use.
