Someone correct me if I'm wrong. Wouldn't he be able to use an newer ignition (stator, flywheel, cdi, coil) and use a lighting coil for a newer bike. I've got an 87 as well, thinking about getting it setup for the street. Lights are one of the obsticles I'll need to overcome. What about using one from a Kx250 along with that ignition? I love the explosive power of the lighter flywheel (have a fww, took it off after 3 rides) and would hate to loose that by going to the newer K5 ignition.
