Re: 96gsx timing
The rectifier converts AC to DC and is involved in charging the battery. Most common cause for backfiring is a carb. problem (dirty, stuck needle, broken reed valve, running lean, etc.). Timing being off is another possibility (many possible causes, broken key on flywheel, debris in stator, bad spark plug wiring, debris in CDI, bad CDI, bad pulser coil). There are many many possible causes for backfiring, but I'd always start with the carbs. if the ski was running OK before, and hasn't been rebuilt recently.
