Works great, bolted right up and everything fit perfect! I haven’t got a chance to really get on it to see if it gave me that much more power but it fired up first kick and it looks pretty cool on the bike too. I’ve just read a few reviews of people saying that, the spark plug don’t clip into place and that’s because you need to unscrew the cap off the spark plug pay attention to your spark plug you out of the bike and notice it does not have a tip on it…

By the wiring harness for a Chinese ATV project and ended up not having any spark traced it down to the coil which was very poorly made replaced with this product quality was better and started right up. Been working fine now for six months.

These seemed to bump up mid range power on our granddaughter's Coleman AT125UT quad. She boogies along at about 36mph very happily.

Complete garbage. I drove down the street and back on a brand new 125cc atv the cdi box lost power and will not come back on. I put the stock one back in now the bike runs great.

I have bought this set before and worked very well so I know what I'm getting and it's a good price, CDI is questionable if it anything extra but if anything it's a good replacement CDI......extra review on spark plug and wire, took out old plug same kind as new one, bike fired right up, plug needed to be changed and i personally will continue buying this plug and wire 100%

Works great after some DIY. The wires on the pin connectors for the CDI needed to be taken out and crimped together. They were loose and came apart when moved around. The coil was completely different from the original. Needed to strip the wires install connectors coming from scooter to hook it up. Used wire ties to "mount it'. The plug end doesn't fit over the Spark plug without taking off the screw on cap off the plug. But with that all said I did get some more power out of Chong. It's a 49cc so you have to be realistic on real numbers but is well worth the $$

This package shipped quickly and is essentially as pictured.Note you will have to remove the adapter on the end of the spark plug to have it fit the ignition coil. I didn't realize this and ended up using a different plug.
