A good spark is necessary for a motorcycle to run. Clean and properly gapped spark plugs may be the fix for your motorcycle if it isn’t producing spark.

Spark plugs may go bad on a motorcycle. When this happens, it  will need to be replaced.

What do I need to change a spark plug on a motorcycle?

Besides the spark plug, there is only one “special” tool you’ll need. You may also need a socket wrench extension if your spark plugs in deep in the engine casing. 

The spark plugs on the Yamaha Virago and V Star 250 are easy to access. 

Here is the list of stuff you’ll need:

I mention the spark plug gap tester because they are good to have to confirm the gap on a spark plug. Or in my case, fix the gap on your brand new spark plug. 

As I was replacing an old spark plug on my V Star 250, I dropped my brand new spark plug. It landed top side down and bent the metal piece. 

The Yamaha V Star 250 manual calls for the gap to be 0.28-0.32. After the drop it narrowed down to 0.1. Being careful with a flathead screwdriver, I bent the tip up to make the gap bigger.

A bad spark plug gap will affect how the motorcycle runs. It may prevent it from running on that cylinder or cause misfire.

The 5 Steps to Replacing Your Motorcycle’s Spark Plugs

  1. Locate the spark plugs 
  1.  Pull off the spark plug wiring harness
  1. Remove the spark plug with the spark plug socket
  1. Screw the new spark plug into place
    1. Start by hand
    2. Finish with the spark plug socket
  1. Push the wiring harness onto the spark plug

Repeat the steps on the other side and you’ll be done. It’s that easy and quick. You should be able to get it done in 5 minutes.

Conclusion

Spark plugs are an important part in the ignition system of any internal combustion engine. If you can replace it yourself, you are on track to getting your motorcycle back on the road. 

The parts you need to get the job done are universal so you’ll be able to use them on other motorcycles and cars. Buy the best tools you can afford and know you will get your money back with the time and money saved by doing the job yourself.
