Jonway YY250t alias Roketa won't start. By miky6719 (Read 1,533 times)

Hello, then my scooter has been parked two months with the battery pack being charged, when I tried to turn left almost immediately, but then after about 30 seconds it was off by itself, when I try to turn the starter motor turns and the battery is good but will not start. I have already replace the spark plug with one new. The starter motor works but the scooter will not turn on. 
Do you have any suggestions?

Thanks

bye

Are you saying it started and you then got on it and started riding it and when you made a left turn it died??

And after that it will not start?

Where was the scooter parked for two months OUTSIDE in the weather, in a garage etc..
Usually after two months or so the Fuel in the CARBS BOWL evaporates and the bowl is empty and it takes a few cranking attempts to get the bowl to fill up with gas. Or you can prime the carb using the VENT hose on the carb to pour 2 oz of fuel in the carb bowl.

I would check the kill switch. Maybe in turning you inadvertently pushed it to off.

[Alleyoop]

Yep, check what KZ said the kill switch, happens to the best of us accidentally hit the switch to the off position and it will immediately kill the motor.

Hello, the scooter parked for two months , in a garage, i look the kill switch under the scooter near the side stand it has a connector with three wires how can i prove i it work fine?

Your killswitch is up on the right handlebar, it looks something like this:

Here is a link for testing it.

Hooray I found the problem!!. It was the switch on the side stand, the bolt was partially unscrewed so it was not a good electrical contact, for the first time what it is on, but then with the vibrations, the contact is open the scooter would not turn on anymore. Thanks for your help!!
Now I have to solve the problem fuel gauge but I'll open a new post

Hello, I am sorry this is my first time posting so I am not sure if I am supposed to post onto an existing thread or start my own. But...

My yy250 will not start. At first it would crank once and then make a sound "errrrr" and nothing else. I replaced the starter and the starter relay. Still nothing. When I try to turn it on it just makes a sound ("errrrrrrr") in the starter relay and nothing else.

What should I look at now?

Or do you think the new relay is bad?

[Alleyoop]

Sounds more like a weak battery, charge the battery up, or if you have a car or friend with a car jump your battery BUT DO NOT HAVE THE CAR running.

The battery is fully charged. I have it on a trickle charger and it states that it is fully charged. I will try anything though...

[Alleyoop]

Even though the trickle charger says it is fully charged the battery could be shot. It could have a bad cell and not enough amps for the starter. If the sound you hear is ERRRRRRRRR that is your battery same as what happens with a dead battery in a car. The trickle chargers are only good if the battery is good.
Get a jump from a car or if you have a regular charger with a meter on it that will charge up a pretty dead battery but a trickle charger will not.
