More reliable ignition – with replacement coil and CDI

Coil and CDI replace aged ignition electronics that produce and time the high-voltage spark required for combustion. Renewing these parts addresses weak spark and erratic timing that often cause starting problems.

More consistent starting and fewer misfires on affected 110cc to 140cc engines, so less time spent troubleshooting ignition faults.

Straightforward electrical repair – thanks to a complete wiring loom

A full wiring loom substitutes corroded or damaged cables and connectors, restoring secure circuits between battery, ignition and auxiliary systems. Clean connections reduce voltage loss and intermittent faults.

Simplifies diagnosis and repair, cutting the time needed to trace wiring faults and improving overall electrical reliability.

Quicker emergency shut-off – with an included kill switch

A manually operated kill switch interrupts the ignition circuit when activated, offering a direct means to stop the engine. The switch connects inline for simple installation and easy access on the bars.

Adds a practical safety control for trail use and makes engine shutdown during maintenance fast and obvious.
