Tools and Materials Needed

  • Spark plug socket
  • Ratchet wrench

Step-by-Step Guide

1. Prepare Your Bike

Ensure your DR250 is on a stable surface and the engine is cool to the touch. Disconnect the battery to prevent any accidental electrical shorts.

2. Locate the Spark Plug

The spark plug on the 1984 Suzuki DR250 is located on the top of the engine. Remove any components that may obstruct access, such as the fuel tank or seat, if necessary.

3. Remove the Old Spark Plug

Use the spark plug socket and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is loose enough to remove by hand. Inspect the old plug for any signs of wear or damage, which can indicate other engine issues.

4. Check and Adjust the Gap on the New Spark Plug

Before installing the new spark plug, use a gap tool to ensure the gap is set to the specifications outlined in your owner's manual. This is crucial for proper engine performance.

5. Install the New Spark Plug

Apply a small amount of anti-seize lubricant to the threads of the new spark plug. Carefully thread it into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to snug it up – do not over-tighten.

6. Reassemble and Test

Reattach any components you removed earlier, reconnect the battery, and start the engine to ensure everything is functioning correctly. Listen for any unusual sounds and check for smooth operation.
