Got a bike engine that just won't fire up? When your magneto and CDI have a current but electricity's just not getting to your motor, it's time to replace your spark plug with this 2-Stroke Motorized Bicycle Spark Plug. With a spark plug gap of .6mm (~.025"), this spark plug is designed specifically for 48cc and 66cc 80cc bicycle engines.
Without a spark, the fuel in your engine won't ignite to create the explosion (i.e. combustion) needed to move a piston and crank in order for your motor to run. When you see your spark plug blacken and corrode, just use a spark plug tool to simply unscrew and remove the plug, then simply install this new spark plug in its place. Once you do, you'll be able to pedal or pull start your motor and get it running the first time, every time.
