My hn125-8 starts up but then cuts out more or less immediately when it should be idling it also cuts out constantly when I break at lights

I have a problem that I,m unfamiliar with when I switch the bike on there is no electrical power but the bike will start using the kick start the other electrics will then work intermitantly, have recharge the battery but am sure the fault is not there and don't believe its wiring so that only leaves components, any ideas witch one. Thanks Harry

I have the same problem... I was going fine then just started to splutter. Petrol is fine, side stand is fine... Could it be a dirty carboretta? It's not the spark plug either... Any suggestions would be greatly received.

the side stand switch is the problem, i have experiance of this. the connector block behind the engine is probably corroded like mine was, there are four wires in the connector block you need to join the two wires that are the same colour scheem and get rid of the switch. a word of caution and safety, every time you set off make sure that the side stand is up.

then i would say its either the cdi unit or primary ignition coil a pick up coil ,secondary ignition coil or possibly the ht cap.

no still no joy

try disconnecting the igntion switch and any kill switches and take the plug out put it and gear with the plug in the ht cap and earth it on the engine and push it and see if the plug sparks then.

no its not that i isolated that when got the bike

ok that sounds like the side stand swiitch is full of water,i would suggest finding the wires that go to the side stand switch and disconnect them then see if it sparks if it still doesnt then join the two wires together on the loom side of the stand connection and see if it sparks then if not then let me know.
