The spark is about the most important thing on the bike,as when you have problemswith spark,clean carbs and pretty paint are not getting you anywhere.The gap is very important,as it determines how long the points are open and closed.When closed,the coil are charging,or storing an electric force,and when the points open,the coil's charge collapses and a high energy spark is released to the plug.the gap also effects timing,so when you set the points,you should check the timing. lha
