Solving Electrical System Problems
If there is no spark at the sparkplug then either there is no electricity in the bike
or the sparkplug is dead. To determine which is the case, remove the spark-plug
cap from the sparkplug wire and touch the end of the exposed wire to the engine.
Kick-start the engine and look for sparks jumping from the wire to the engine. If
there is sparking coming from the wire but not from the sparkplug then you know
the problem is with the sparkplug. Replace it. If it still does not work then you
know the problem is with the sparkplug cap. Ensure that no water or oil is in the
sparkplug cap and that the clip inside the cap is strong. If the clip is weak, use a
paper clip to connect the wire to the sparkplug directly or get a new sparkplug cap.
If there is no spark from the sparkplug wire to the engine mount then the
problem is with something in the electrical system. Because the electricity goes

Sometimes the casing for the start/stop switch on the right hand side of the
handle bar can get wet or fouled with oil. This shorts the start/stop switch (same as
turning the bike off) and makes the bike look like it has no electricity when in fact
it does. So the first thing to do when you have an electrical problem is eliminate

metal like a fork end or the tweezers from a Swiss Army knife to do this as there is
a small catch on the clip. By doing so, you remove the key and stop/start switch
from the electrical system's loop. If you can now start the bike, then open up the
