Was given a non-running chinese GY6 ATV, and it was barely getting any spark & would not fire no matter what I tried... After changing Carb, Air filter, coil, spark plug, battery, and voltage regulator, I still could not get it to fire... Digging deeper, I discovered that a previous owner had changed the CDI to one that looks like a mini car amplifier with no markings or labelling on it at all. After determining this ATV was of the DC variety (rare to be DC, but lights working with key on was a dead giveaway it is a DC bike), I bought this thinking there was nothing left that could keep it from getting agood spark. I was right!!! Once it actually fired it still did not want to rev, but that was just due to a stuck slide in the brand new carb... This CDI was super simple to install, ad the price was perfect fro reviving the chinesium ATV. It's a bit larger than the spot the original was, but a little creativity & I got it mounted pretty solid in the spame spot. I was pleasantly surprised how quick this little thing revs once I got it going. Never expected the 150cc GY6 to be so responsive. I do not have any stock reference to compare to, but I have top assume it was not as snappy with the stock rev limited CDI installed, nor the aftermarket one that was already installed when I got ht ebike. Only complaint I have with this is the adjustable timing... Not exactly sure where it needs to be set, so I put the adjuster in the middle. Hopefully it is safe there... Need to clean up some wiring, change to some super bright LED lights & make it look half decent, then its off to a new owner who should be able to enjoy it for many years to come!

I bought this optimistic that it was either gonna be a total waste of $12. or it was gonna be worth it ..and it was beyond worth it...My KYMCO agility 50 was maxed out at 29mph before I installed this, and now I can get 45mph and that was just with this installed, once I do the variator and the collar...I bet it will do 50+mph. Easy to install, no adjustment needed...did have a few hiccups occasionally if I was at higher speeds and let off the throttle some then got back into it, sometimes It would bog but I didnt do it again after those few times, but either way it made a huge difference.

Not sure if defective unit or what. Does not function or did not fit. Did not spark. Quality is OK. A known working CDI functions just fine on the bike, no response from this one. Update: ordered a replacement and it didn't work as well. Likely mislabelled description and that this is an AC CDI?

It's very reliable my bike starts first try and I can fine tune it according to weather etc

La instale en una tank 200cc ((gy6 169cc)) con el carbulador de fabrica y no note mucha diferencia al mover el tornillo lo cual pensé que no valía la pena pero luego de instalar un header y pipa más grandes y un carbulador 28mm cortina plana es otra cosa, si pongo el tornillo en el medio como si fuera de fabrica falla, se embucha de gas, si lo doy al tornillo para el lado derecho siento la potencia después de las 55 millas y si le doy a la izquierda encontra de las manecillas del reloj arranca con más fuerza, lo único que pierdo 2 millas máximas cosa que compensa al llegar mucho más rápido al límite. Si tienes carbulador de fabrica y mufle de fabrica no vale la pena, pero si quieres instalar carbulador mas grande y mufle es un requicito tenerlo para poder tener la mezcla a punto

The timign ajustment does do something, when turned down, it makes the machine go slower, up, a little fast, but Much slower then stock. All i have done so far is added a Variator weights sliders 7g, and the unrestricted boss. With these and stock CDI I was getting 34-35. With this and any ajustments top speed around 33mph and slower acceleration. Still going to tinker with the jet at 82 as per unrestricted as the manual from kymco says. Perhaps that will help. Else took it out and running stock again.

It works. Does adjusting timing

Put it in my 2015 kymco agility 50 about 1 year ago and it has worked very good. It unrestricted the rpm and allowed it to go 47mph (on a slight down hill). I made some upgrades and the screw in the little blue square thing got turned, which I seen it was for timing and I don't know which way advances or retards it. Update: read more on it and it explains the timing advanced adjustment. I just overlooked it.

Does not work on ajs jsm 50
