The motorcycle’s spark plugs should be replaced every 8 to 10 thousand kilometers although manufacturers clearly state that a spark plug should be good for 10000+ KMs. offers you a wide range of parts and services for your motorbeast, it is always to look up to the professionals if you even a wee bit skeptical about DIY.

If you’ve never done it before, don’t panic; it’s a simple procedure that can be completed with a half-decent set of tools to remove any bodywork or chassis elements that are blocking your access to the spark plugs. A spark plug spanner with the proper breadth and length, as well as a torque wrench for tightening the new plug.

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.

On any motorbike, the first thing you should do is remove the “plug wire” from the spark plug. 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. Grip the boot, which looks like a small cap on the end of a spark plug, use your fingertips thenĀ  twist the boot gently until the wire comes loose.

Step 2.

It should be cleaned, before you remove the spark plugs, clean them with a little cleaning agent and a moist cloth. When removing the spark plugs from their location, use a compressor to blast air over them.

Step 3.

Using a wrench of appropriate size, remove the old spark plug. As an added precaution, block the hole to prevent debris from entering the engine, then install the new spark plug by hand tightening it first, then tightening it with a spanner, but be careful not to over-tighten the plug as this may damage it.

Keep in mind.

Finally, you’ll want to put everything back together in the same sequence that you took it apart. 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.
