- | A condition in which the fuel/air mixture ignites before the spark plug fires. This is often caused by carbon buildup in the cylinders/ top of pistons which can allow the engine to seem to "run on" ((Haynes Sportster manual 1970-2010 pg REF*51)) | + | A condition in which the fuel/air mixture ignites before the spark plug fires.

===== Pre-load (bolt-fastener) ===== | ===== Pre-load (bolt-fastener) ===== | ||
Bolt pre-load is basically the spring pressure that holds materials together that is applied by the bolt. Once a bolt is tight, it doesn’t turn any longer. You have a mating surface (underside of the bolt) touching the mating surface it is on. Any further tightening will stretch the bolt in a circular motion that adds clamp force to the mating surfaces. The amount of clamp force needed depends on the materials and application. All bolts have a spring pressure limit called a point of “yield”. | Bolt pre-load is basically the spring pressure that holds materials together that is applied by the bolt.
