Here you go, follow that wire and it will go to the Spark Plug:

thank you! i guess i will have to remove even more panels from the right side then? if its the thing i can see under the battery on the right side of the scooter. I can reach it, is it just pullable?

If i dont have any extra spark plugs at home I wont get it to work for tomorrow morning anyways right?

Well we are going to the tests right now to see if the Spark Plug is Sparking if it is then it is something else. Also check the two wires that connect to the other side of the coil wire I pointed out. Make sure the two wires are on nice and tight on the connecters and not touching.

If you have Spark then it may be fuel delivery problem and or Valves are to tight and you are loosing compression.

A friend who is an electrician is helping out were we cant get no spark maybe the killswitch is bad

Will be diagram #2:

The linhai version, this is the diagram drawn off of an exact linhai, mine. Note: the kill switch can be bad but I would check for 12Vdc+ on the black wire to the CDI first with the key on. This is a DC powered CDI system, no power = no spark = no run. If you have power on the black wire to the CDI then tell your electrician to take his meter set to ohms and test the gray/white wire to the CDI to ground.

With key switch in the on position and the kill switch in the engine run position he should read no ohms resistance or no continuity, if so then the kill sswitch or the key switch could be bad or the gray/white wire has grounded out to the frame somewhere?

If the kill circuit checks out OK and you have 12Vdc on the black wire then you've got a bad CDI or bad coil or bad wire (black/yellow) from CDI to coil or a bad ground to either of them.

I'm just reading and learning, no wisdom to add, but I'm amazed to see yet another name for the YY250T.

Actually not a true YY250T as noted earlier. How about Zscoot?
