I'm hoping someone's experience will save me some trouble. The last
three times I have ridden my 80 KZ750 it has gone down to two
cylinders when restarted. I have ridden for about an hour getting to
my destination. About an hour later I come back to the bike to ride
home. When I start the engine, it runs on only two cylinders; the
#2-3 combo. The #1-4 are dead with no spark as they share the
ignition. I have enough power with two cylinders so I head for home.
After about 3 miles, the dead ignition kicks in with no further
trouble. It runs great all the way home.
I cleaned the wire connectors, tightened the connectors, ohmed out the
sensors and box which all test good per the manual. A few months ago,
I installed new Dyna coils. When I installed the coils, I worked all
the 12V connections to the coils to reduce the voltage loss in that
long convoluted wiring mess.
I'm wondering, is this the classic heat soak behavior of the solid
state device? Is swapping on other components the only way to check?
Thanks for any advice or pointers.
The KZ is too much fun for an old guy like me!
