So I purchased one of those keyed "performance" cdi and coil ignition (like the huffydavidson or jaguar sets) units from an online motorized bike site hoping to improve over my spotty stock integrated cdi unit. I installed it and got no spark, contacted the site who was unable to provide me any diagnostic information and so sent me another in hopes that the first was bad, I installed and still no spark. I ended up re-installing the stock unit and ran on that a little over a year, but it has just finally spent itself (tested out of spec as listed on the "so your China girl won't run" Google doc). I've ordered a new stock style replacement and am waiting, but that I'm doing so with a theoretically good performance set just sitting here is sort of a kick in the pants. Does anyone on here happen to have a way to properly test the performance cdi and/or coil or perhaps why it wouldn't fire in the case that it is good? I'm really not a fan of open ended mysteries, especially when they cost money and frustration lol
