GZ125 Missfiring after a failed theft, Help :(

[deathbylemons]

had an attempted theft on a gz125 2006 who's owned by a roommate and want to get her back on the bike

The bike had three wires cut from ignition barrel two reds and a black and white, awkwardly can't find a wiring diagram but bike runs with the wires conected to either pair of wires,

but there is a constant missfiring problem but the bike was fully operational before the crappy attempt of an theft as they just blew a main fuse and left it


any pointers to why it is missfiring? battery didnt drain and has 12.6 volts, spark looks strong tried a new spark cap just in case but no imporvements

I hope the electronics aren`t damage with the shorting out.

6 wires in total but only three where cut but the theft shorted and blew a fuse, reconnected wires and had power back but missfires when under load but happy when reving on the spot

Is it possible that the bike has been on its side and oil has come up the engine breather pipe and into the air box / filter ?

I've is up and running now, it was one corroded pin on the cdi, decided to only cause a issue after the attempted theft, what a pain in the ass, thanks for the help the owner is very happy bunny now
