GSXR 400 gk73a ignition problem

Post by detlevsnitzel » Fri Oct 13, 2017 9:23 pm

This morning i was going for a ride, but unfortunately my gk73a wouldnt start.
I use the bike every day as transport, but the problem appeared over the night.

The bike has no spark on all 4 cylinders. (i have tried other spark plugs)
The starter is runing fine.

Does this problem sound familiar to anyone in here? cause im pretty lost here.

Few ideas to try
- sidestand switch, you can bypass this easily
- pulse coil wire snapped at engine cover or coil defective. 100 ohms is what the coil should measure from the 2 pin plug near your battery box.
- cdi dead or corroded connections in connector plug.

good luck. ;)
