So, is it possible that changing spark plug wires can make my bike run better?
A. Yes. A spark plug wire that is in good condition will make your bike run better compared to a poor quality or failing wire. This is becasue a good wire will transmit more of the coil’s power to the spark plug. Poor wires “waste” this power due to high electrical resistance or by arcing through failing insulation. A powerful spark is important becasue stronger sparks initiate more consistently timed and more complete combustion in your engine. This means that good plug wires will make your engine produce more power while wasting less gas due to incomplete ignition or misfiring. Even if your wires are brand new, they could be costing you power if they are of substandard design.
