i don't know if it's me but seems like all these zx'rs are having the same problem (allright not all) but the CDI seems short lived. has anyone else noticed the short life span of these units? maybe it's just me but i found three (or was it four) posts with what i would call the same problem. some just die, and others limp, but they all have the same cause. i explained in another post i have been trying to find a reliable cdi for my zx, and if i do i will post the results. thanks for all the good advice ... keep scootin
