I50cc scooters are cheaper and quick mode of transport that you can use without raising your fuel budget. You need to regularly update and maintain your scooter’s engine just as you do to the vehicles. One of the main components is the spark plug. This should be changed every time it burns out.

Once you buy your scooter, get familiar with major components of the engine, their locations, and way to troubleshoot each. They include the head gaskets, spark plugs and the battery. Understanding the basics of the engine will make it easier to diagnose the problem within the system.

Read the spark plug

To check if your spark plug needs any change, warm the engine for a few minutes and check the spark plug inside the ceramic insulator. A well working spark plug should be tan or brown in color. If the plug looks too light, then your engine is running to dangerously hot temperatures. If it is wet looking or too dark, then its carburetor is too big.

You may also change the plug if you find that the ground and electrode are gradually been eroded away. You should also check for faulty ignition leads and breaker points, weak condensers and coil and also the sticking valves. If you find that, the plug has a black, oily sludgy deposit, look for a hotter plug to replace the damaged one.

Replacing the spark plug

Locate the position of the spark plug at the top of your scooter’s cylinder. You need to have a 13/16th inch wrench to loosen the spark plug. Place the wrench around the top of the spark plug and wiggle it slightly. You can remove the spark with hand after it is let loose. You should not do it when the engine is running.

Ensure that you have bought a spark plug without any visible damage. Most spark plugs will work just fine if they do not have any visible damage on the surface. Install the new spark plug on the socket that the old spark came from. It should pop into place without much ado. Use the wrench to gently lock it in place. However, your hands can still do that. Cover the outer part of the spark plug with a protective covering.

Return everything else into position and start your engine. The new plug should pick as soon as you start the engine. The procedure does not require a professional technician.
