3rd CDI box to go out in two months

[ed52]

I think i am have a problem. I've had a vortex ignition box on my Z for two years now! Back in NOV it went out on me, so I replaced it with a PRO-com box, then after two rides that one went out, then I replaced that one with a big gun and after 4 rides, this one is fried too! I've replace the wiring harness. What could cause that problem?

[firebug]

don't know about the first one but probably the reason the last two went out is cause they are both procoms. most of the procoms are crap

ProCom are junk. Yosh is also made by Porcom too so say away from any of them. DYNA is the only way to go!
