It is the luck of the draw with any cdi. Color means nothing. They are all mass produced ..painted.. and packaged in China by numerous companies that like to copy one another. The only sure way to tell if a cdi is advancing the timing at higher rpms is by hooking up an induction timing light....taking off the flywheel cover and observing the setting with the engine running. I have tried orange-blue-3blacks- and recently a black one that claimed to be adjustable. The only one that actually advanced the timing was the orange one. At idle it was 2° btdc and would advance to 12° btdc between 2 and 3 thousand rpms. All the others were set at between 10 and 12° btdc. With no change at all at any rpms. The adjustable one was the same with the adjustment screw making no difference at all. All the ones with the 12° btdc resulted in a faster idle. But with the advanced timing at low rpms it puts more strain on the engine under full throttle acceleration. The orange one at 2° btdc and then advancing to 12° btdc is smoother. Just my 2cents. P.S. I am not promoting the orange one. Like I said. The next orange one might not have the same results.
Any non believers out there please check your results with a good timing light.
