I am trying to trouble shoot same problem. I have replaced transistors and all capacitors in the TCI module, I have swapped pickups, and rewired bike to verify that coil is good, plug wirs, TCI (both channels) and pickups are all good. I still can´t get teh outer two cylenders to work. If I pull the plug there is a bright spark, and plug is wet with fuel... Why won´t the outer two cylenders run ???????
