My ZX-50 starts and runs great but dies after 5 mins or after top speed.

Try cleaning the carb. and getting a new spark plug. These are really the most common problem.

Sorry for the thread necro but I've got a Kymco ZX50 "super fever" (HAHA) in here with the same issue. It fires right up and idles fine. I took it out and rode it around the lot for about 5 mins and it was like I hit the kill switch - it just died. It was the end of the day so I pushed it back into the shop and left it. I came in this morning and it fired right up. I went through the carb and that's perfectly clean. Does anyone have any wiring diagrams or testing info for the stator for these units? We're a Vespa/Piaggio dealer and former Arctic Cat dealer so I know electrical testing, I just need to know what kind of values I should be seeing. I'm guessing it's either the stator or coil that's breaking down when hot. Thanks in advance!

the manual is in this thread, and has the specs you need... links to service manuals...

But the info will not help unless the issue is FULL TIME, and not intermittent. I have read components as within spec. when cold, and fail when hot.

Just get all the bits on Ebay. They are listed as Fever ZX or Dio. Either one. If you want it easy make sure the CDI has TWO plugs. Other wise you have to hardwire a one plug (five pin) cdi.
CDI + coil is under 20 bucks, and a stator is under 50.

The listed stator is OEM manufacture, and the CDI/coil are aftermarket but better. The OEM cdi is 80 bucks, and they ALL fail.
