Tytronic Built:

This electronic ignition is designed and produced by Tytronic,duty cycle is designed at 50%. In every ignition when ignition first senses the signal,ignition will turn on automatically then supply power to the ignition coil. When it senses the second signal this will trigger coil to ignite.This is the complete ignition process. The duty cycle of the original bike is about 50%,and some ignitions you can buy in the market are about 95%. Too big or too small of a value the ignition system energy you will experience insufficient spark and poor performance.
