This CDI unit is a dual band version where you can have to setting, whether to have normal or tuned-up riding style.
There are three version of BRT CDI unit that is Standard Tune-Up(ST), Tune-Up Racing(TU) and Racing Kompetisi(RK). The most CDI unit used by most Yamaha LC135 is the TU version. This because it has the fan control, thus can give better cooling to the engine. RK is not recommended even though it has advantage of 16-programmable point of TDC because this one is used mainly only for real purpose racing in track. And you should also know that this CDI unit cost more than RM600.
The fan control connector is on the right side of the green wire.
