Checking and having the correct spark plug gap plays an important role of how your motorcycle will perform. Instead of using a caliper to measure the gap (which can be inaccurate) we have this handy-dandy spark plug gap checker tool. This tool allows you to measure the spark plug gap and the top hole allows you to open or close the gap. Measures 1 1/2″ in diameter. We use this same tool on our bikes here at the shop. Great for motorcycles, cars, and everything else in between.
