What is the procedure for inspecting spark plugs?

Disconnect the spark plug wire from the spark plug to test the spark plug ignition. Hold the spark plug wire close to a metal surface, rev the engine, and look for a spark at the spark plug tip; if the spark plug is good, you should see a spark or hear a crackling sound. This indicates that voltage is reaching the spark plug via the wire.

Step 1.

This wire links to the coils on your motorcycle and is quite simple to remove; on most bikes, you simply pull up on the plug wires lightly to separate them from the spark plug.

When reinstalling the plugs, it is recommend carefully tightening them to avoid stripping the threads. After hand-tightening the plugs, gently squeezing them into the cylinder head with the socket is recommended. This is followed by replacing the plug wires on the plug and you’ll be good to go.
