6. Fuel valve/petcock or filter clogged.
7. Discharged battery, loose, corroded or broken battery terminal connections especially the "NEGATIVE" cable inside the harness at both ends.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.

SOURCE: CDI help
You can't, just went through this. You'll need to find the correct CDI for your bike, some years will switch back an forth but rarely and Suzuki has never printed, that I've seen, a wiring diagram for the CDI. The 94 might work if you can find it and it should plug right in, the 98 will have a different curve that most likely wont.

check kill switch, then battery for full voltage, 12.5V Check fuses and wiring for loose connections.
If you have the wiring diagram check ignition switch, do the simple stuff, before you start replacing coils or sending units on the ignition system.

Check the valve adjustment. If a valve is standing open just a little, the compression will be too low to start the engine. Check fuel delivery by dribbling a little gasoline into the carb and try starting the bike. If it starts and runs for a second or two, you're not getting fuel into the cylinders. Check you carb again.

One, or more, of the three necessary ingrediants for combustion are missing: fuel, compression, and a spark (at the right time).
You said that it started to overheat. Find out why. Then, check the engine's compression. You need at least 140 psi of compression, in every cylinder, for the engine to start and run. Low compression indicates either the need for a valve adjustment - or serious engine repairs.

Testimonial: "cheers mate will conduct a compression test and take it from there. thanks. "
hi,sounds to me like your cdi pickup unit has failed,i am not 100% certain but this will be located on the end of the crankshaft behind one of the enginecovers,there could be two other possibilities,motox bikes are notorious for breaking wires so check the wiring from the cdi sender unit to the cdi box and the coil,also check your "off"button it may be stuck in the "kill" position..hope this helps..cheers ian
