I have consulted the users manual for changing the spark plug on a motorcycle. However, I was interested if anyone can provide some more advice on how to poperly install them.
Always make sure the treaded area is clean and never put any type of oil such as WD-40 on the thread. You may want to take the time to properly insert the spark plug so it is threaded properly. The importance of doing this is to avoid cross- threading. To tighten up the spark plug, I suggest using a torque wrench.
