I have a Yamaha vity 125cc moped that been having problems starting up I’m on it daily for work but there’s been a couple of times when going to start it and it don’t start. Sometime when turning the key you hear a huming sound and the engine light comes on so I know it’s not dead but on sunday I got on my bike turned the key the engine light came on but no humming noise so when I tried the engition switch it was trying to start but just wouldn’t so I tried it a few more time and the sound from the engition switch started cutting out and at one point I press the switch and nothing was happening. Yesterday my bike was sitting over night I went out to the shop about 15mins drive from my house after 10mins in the shop I got on my bike tuned the key engine light came on but when I pressed the engition key it tried to start but just wouldn’t start running I ended up pishimg my buke for 20mins in the sun trying to start it evey 5 mins in the end I slaped the front panel near the light a little hard like 3 times out of fraustration tried it and got running.
To me it can’t be the battery because for one the engine light come on when turning my key plus the battery only charges when the bikes running so it so on Sunday if the batter was dead it would charge up sitting on my drive way all night.
Spark plug I’m not sure about again to me the bike does start so unless the connector is loose.
Engition switch I can’t see it being that as it works and yes it did cut out which is why at first I thought maybe the battery was about dead but it can’t be…someone told me the fuse on the battery, loose wiring or the carbaretor but I don’t have a clue mainly because now since all this I’ve got the bike running 3 times now and everything seems fine the engition light comes on with that humming sound after turning my key and when I press the engition switch a few kicks and boom it starts so if anyone has any ideas what the problem was or is and will it happen again if so what should I do as I’m stumped for ideas. Thanks
