Gary Smith what a useless comment to make. And this woman is looking to change the spark plugs on her bike. Maybe try thinking before you make worthless sexist comments on a video that someone took the time to make in order to help people.
I just bought this bike used and was looking up spark plug videos to know where they are and how many there are, not how to change them. No matter how much you think you know it's always better to do research when venturing into new toys.
