What causes a dirt bike to not start?
Spark – This is usually the first thing that everyone suspects when a dirt bike won’t start, but this can also be misleading because a plug will frequently fire out of the cylinder, but under the pressure of being in a cylinder, a spark plug will frequently fail to fire and light the air / fuel mixture.
Holding the spark plugs up to any piece of metal (such as the head bolt), turn over your engine. If you do it correctly, you’ll see a spark from the electrode going towards the metal part.
