MPS Timing Light Adapter

The MPS Timing Light Adapter was designed to allow the use of a standard inductive timing light on a bike with stick coils. Just unplug the coil from the spark plug. Slide the spark plug boot onto the spark plug. Push the screw end into the stick coil. Clamp the light onto the wire. Checking the timing is a must when installing stand alone ECUs. Most modern bikes do not have timing marks. You will need to make the marks yourself. This will require you to set up a degree wheel and make your marks. Some bikes will require you to get an extra engine cover to modify with a hole and a pointer. Hayabusas can be marked on the starter clutch with a punch.
