Default Shocked while touching rear spark plug wires??

My bike is recently started to randomly stall during stops so I tried wiggling the spark plug wire to see if it was seated correctly and got zapped.. Does this mean my wires are bad or maybe my plugs? Thx

Unless they weren't properly seated on the plug I would say it's time for a new set of wires.

Electricity is lazy. It will follow the easiest path of resistance. I would replace the plugs and wires.

I would prefer to say the darned stuff is cunning and devious! Otherwise I agree, replacements are a good idea. But don't stick your fingers where......

I seem to remember my auto-shop teacher back in the 7th grade say "Never grab hold of your spark plugs with the engine running!". There's some high voltage running through that 5/16" piece of rubber.

I am not subject matter expert on your issue but I'd like to pass on something I learned as a teen in the US Navy.
Before grabbing any electrical conductor touch it with the back of your hand first. If you're zapped you'll pull your hand away.
If you grab the wire/cable/conductor and there is voltage the current may cause the muscles in your hand to close more tightly since muscles are controlled by your body's electrical system the nerves.
I remembered this and still use it today before grabbing any wire.


In shipbuilding I always did this and did get pop'd a few times.


Just sayin

Older graphite sparkplug wires would zap you anytime. These are the type with older distributor and points ignition systems. The newer silicone based with some kind of core conductor usually won't shock you unless there is a break down of the insulation. This is probably what happened. Remember you are dealing with tens of thousands of volts and it can jump a long way. Even if you think the core is insulated. New plugs and wires should solve the problem.
