Slow spark

Recommended Posts

Im looking at buying a drz400e. The guy has changed the stator, coil, checked the cdi box and checked the magneto and says everything is working the way they should be but still has the slow spark. Says when it turns over it sparks every couple of seconds but not consistent. He thinks it could be a short in the wires. I just wanted to see what other people thoughts are about this and what could be causing this problem

'Slow spark'??? That is a new one. Either it sparks or does not.

Poor spark could be a bad battery, poor connection. I am assuming the guy used OEM or high quality aftermarket (and not 'ebay cheapies' for his stator/CDI and what ever else he was guessing at). Just changing parts willy-nilly rarely solves the problem.

Buy it cheap.  Stators often go bad, OEM CDI box never goes bad, a bad coil would be extremely rare, the regulator/rectifier is quite relable but not part of a spark problem as long as there is battery power. Magneto?? that would be the flywheel, stator and regulator/rectifier already covered above.  Inexpensive replacement stators sometimes do not solve the problem.  As long as you get the original coil, CDI box, and regulator/rectifier you will probably not be into it for more than $200 for a good replacement stator.  Buy it for a price relative to overall condition, the fact that it does not run and needs additional repairs, and you are taking the chance on what else might be hiding.
