Hello I have a 125 four wire ignition with electric start, but they disconnected, have to kick start.  My question is how to hook the two wires to ignition back up, it fell off one day when wife try starting it or can it be by passed 125 Yamaha 

Hi James, welcome to the forum. Ideally you should have introduced yourself in the newbie section first.

First of all, don't blame the missus.  If you can see the two wires and the connections where they should be try soldering them back.

Hope this helps and good luck.

Mike.
