Question about 2003 Hyosung Comet 125
Hi and welcome to fixya,
This can either be a Timing problem or bad fire. If you say the plugs are sparking, then it can be that it fires where it shouldn't be firing. The misfire can also be caused by a double fire on the plugs. Time the engine properly, adjust the timing chain, check for proper engine compression as well..
Hope this helps
