a friend of mine have a 96 ZRT6
After installing VForce reed valves it started eating sparkplugs and didn't
rund properly in the mid register
We checked the voltage on the sparkplugs and found that only two of the
sylinders got proper spark...the dual coil seems to not give enaugh voltage
seems like it gives enaugh voltage to the sylinder fiering first but
only have leftover voltage for the last one...
We changed the coils to three seperate (from a polaris by the way)
now we got proper spark on all tree sylinders and a noticable better running
engine....doesn't have dynotest or we would have tested it....
only problem we got was a bad wire from the cdi to the ground...
