I'm completely unfamiliar with this ATV.
What kind of CDI do you have? You said you bought a new one. Do you have links to the one you bought? How many pins were on this CDI?
Do you have a wire diagram for this ATV? Or better yet, do you have links to a downloadable wiring diagram?

The reason I was asking about the CDI pins and links to the supplier was just to form a plan of attack, and not to suggest the CDI is bad. The CDI is in the middle of the ignition system, and that makes it a logical place to start. The CDI has to have some sort of power supply (and ground) to run it (which could be 12 volts DC or moderately high voltage AC), a timing trigger signal from the stator to tell it when to fire, an output to drive the ignition coil, and a maybe a kill switch input.
So the first task is to identify the wires going to the CDI and figure out their function. Then measure continuity and voltages from the CDI connector back through the wiring and to/through the devices they connect to. If any glaring faults turn up we have a direction to focus on.
DO you have a meter?
So "I think mayber 5 or 6 wires" isn't good enough info to start on. And again if you have any links to the CDI vendor that would help too. I didn't ask this in my last post, but what are the wire colors in the wiring harness that connect to your CDI?
Electronics that is powered and sits under water starts a corrosion process that attacks in ernest anything that is powered up positive relative to the biggest conductive mass (i.e. frame ground). So carefully inspect all positive battery connection wires through the fuse to the ignition switch for corrosion damage. Sometimes quads have the voltage regulator output connected on the battery side of the ignition switch, so inpect the regulator connector too (but this is most likely unrelated to your no spark problem).
