This rapid sense system from Malossi is for both 4 stroke and 2 stroke bikes. It has an hour meter, cylinder temperature sensor, and rpm counter. The rpm counter works simply by wrapping the wire tightly around the coil wire and counts pulses and the temperature gauge works with a sensor that is designed to be mounted into a cylinder head that has been machined for the sensor to thread into it.
