First thing that I would swap would be the coil – I have found that no spark is usually a simple, yet overlooked issue. Sounds like your CDI is a 99, where his may be an earlier model. Last thing I would be doing though, is shorting out two wires in which I didn’t know the purpose – good chance of ruining a good CDI. Wires are color coded for a reason. The two wires which are not connected, may very likely be to a kill switch, in which case would cause you to have no spark when connected together anyway. Try a coil swap and find out what the wires are before shorting them. jmo
We may not be the fastest on the track...but we're having the most fun!
