you have to hold in the brake lever in when starting the scooter .. there is a electrical (grounding)
lockout to keep scooter from starting unless lever is pulled in..however kick is always good.

2 types of scoot electrical systems .. ones that headlights come on with key on (battery)
and ones that come on when motor is started.

as for the other loose wire  picture   please post it here

thanks... you are too quick for me. I modified my post to remove the question about the kick starter because I read the user manual and it stated the brake had to be held in for it to start. Woops.

I have tried to attach to this post.

good for you, but since its the plug and not really motor  or tranny issues  you
might have a hard time convincing the dealership to take it back.

plug issues are very hard to diagnose due to the very different symptoms they cause.
usually its a good idea to replace plugs just on general principals and most always
give them a look for the things they tell about the motor

Hi Harry

Ended up taking it back to the company I bought it and they said the reason was a dead spark plug that had coked up and the plug cap had burnt. Said that this was causing the fuel from one cylinder to be pushed into the exhaust system without firing and so caused the heat in the tail pipe. Changed plugs and plug caps and told me to collect it. Seemed ok, but had another fire on the tray below the engine and seems like some fluid is coming from somewhere, all within an hour of collecting it from them, so I've sent it back and now don't really want the bike back. I am wondering if the plug issue was the truth about the original problem and they blowing smoke up my arse. Thanks for your earlier suggestions, it was probably closer to reality than what they suggested.
Regards

exhaust valve maybe out of adjustment and not closing all the way
so when the fuel explodes it leaks out of the cylinder as a 1000F/550c flash
overheating the pipe.. also you would have loss of power.
pull the cover and measure the lash....sorry i wasn't clear on the "a bad valve"

find the red wire in the connector .
use a meter  to test red wire and ground.
turn on the key but don't start motor...
if you have 12-13 volts you have a DC CDI.
