Hi

My Kymco Top Boy start easily if I kick start it.

When I use the ignition switch, it only start (almost immediately) if I 'wiggle' the key slightly while holding the starter button in. If I turn the key first, leave it and then press the starter button - then the starter turn but the engine don't start. I suspect it don't get a spark in that situation.

I assume it can be one of two things:
1) Faulty ignition coil.
2) Worn out ignition switch

The ignition coil should be easy to replace.
Although I can find a replacement ignition switch (link below), it seems both bolts used to hold it in place on the frame of the Kymco don't have a shape for a spanner. (Rather that the head used to tighten the bolt in the factory sheared of at a certain 'correct' tension.)

So i have two questions:
1) Is my assumptions on the two possible causes correct?
2) Any advice on how to remove the factory fitted ignition switch from the frame?

Thanks, g

If you have to wiggle the key to get it to start...it's the ignition switch.
You are correct that the factory bolts "shear" off at a certain torque to make them harder to remove...theft deterrent.
You can easily back them out with a flat blade screwdriver if you use a dremel with a cut-off wheel to cut a slot in them.
Just take your time with the dremel and make a nice straight, centered slot.
