Question about 1985 Yamaha XJ 700 X Maxim
Misfire on over-run.The spark appears to be weak on rear cylinder which will not fire until warmed up,if i increase the revs to about 1500 the rev counter drops to zero.I have checked coils,leads,plug caps,wiring loom earths etc.The output from the CDI unit reads approx.8volts to the front coil,and below 2volts to the rear coil.I suspect the CDI unit is faulty but do not want to buy anew one until I am sure.Can any one help with tests or suggest anything else which would cause the problem.
