1987 classic 50 oil injection did not come with motor .I have replaced every part on motor dealing with spark still no fire. new coils , new stator , new trigger, new cdi box. what else do I need to do. thanks for anyhelp
Sounds to me that there is an issue with the ignition switch or the lanyard kill switch.------That system stops sparking when the circuit is CLOSED.-----Up to you to do some trouble shooting.----Also if your starter is weak / battery is weak you will not get spark if motor does not crank fast enuff.----Have the battery load tested.
