Postby Venum » Mon May 12, 2014 10:41 pm

Probably cdi at fault. Try swapping your cdi connectors around and see if the problem moves to nr 1 and 3 cylinders.

Also check the 4 wire plug to the left of the battery for corrosion.Its the pulse coil wires

Same procedure.unplug and swap the 2 ignition modules.If it's still no spark,check the pulse coils.if there working,then the ignition wires and caps and finally the coils.
There are volt and ohm tests for each part,except the module.
