the coil could be good?
the alloy performance cdi's are only really good for lightening your wallet
they either don't work straight up, they could advance your timing too much, or fail prematurely

do you have a 5 pin cdi or a 6 pin cdi ?
all the electric start 125's i have played with were 5 pin, but your's could be different.

that terminal that isn't used in yours is just an earth, it should be fine without it.


but just watch out, the 6 pin CDI's have 2 different types, an AC fired and a DC fired,
you should be able to work out which one by this pic





the other black alloy box is your voltage regulator/rectifier,
it's only used if you have a battery connected and want to charge it, for starting and lighting etc

there are a couple of performance type cdis here-

the one in your link looks like it has rounded sockets too, compared to the square/rectangular ones in my pic

i cant tell by your pic, but just push the tab in and unplug it then you'll know for sure
here is one with squarish sockets-
6 PIN Ignition CDI Unit 150cc 200cc 250cc PIT PRO Trail Quad Dirt Bike ATV Buggy | eBay

the cheaper racing cdi's aren't worth the trouble you will have, like the Alloy ones i mentioned earlier.

unless you are buying a decent brand CDI like a TB, OORacing, Takegawa, Kitaco one, but they can be expensive too
