...the bottom pic of the three in that link has a sticker with a part number on it...that is a unrestricted cdi that was in an A50 of scootermaven's...
...what we would need to know, is the colors of the wires that are connected to your cdi...
..if you have no pink wires connected to your cdi,and your cdi does not have a label pasted to it, then most likely you have a stock, restricted cdi...
..if you have no pink wires, then you need only to notch the cdi, as in the upper two pics from that link, to de-restrict your cdi...
..if you have pink wires connected to your cdi, then clipping an external wire is required to de-restrict your cdi...
..below is a pic of my dealer-cut cdi...do your wires appear to be the same color as those??
..note that the red wire in the pic does not go to my cdi, that is my battery's hot wire...
..as you can see, cutting a small 1/4 inch notch in the edge of the cdi's casing will harm nothing, even if there is no internal wire there...
..however, if there is, then you have instant speed!!
peace
