Motorcycle Repair: 78 KZ 1000, dyna coils, lt side

Question
THE TWO CYLINDERS ON THE LT SIDE OF THE BIKE HAVE NOI SPARK. I CHANGED THE COIL AND STILL THE SAME. IT HAS A DYNA S IGNITION AND DYNA COILS. HOW DO I CHECK THE IGNITION.  OR WHAT SHOULD I DO NOW

Answer
Hi John,

Each ignition coil fires two cylinders. One coil fires cylinders 1 & 4, the other coil fires 2 & 3.

From the description given, I suspect you have one coil secondary lead (spark plug wire) connected to the wrong cylinder.

If not, check contact breaker points condition. Set the gap and adjust ignition timing.

Send me an email and I'll return several files that may assist you.

Respectfully,
Mark Shively
