1-2-4 are easy as can be, #3.....ROYAL PITA...Only had the gen 1 Z1000 for a few weeks now but I ride 500km a week to and from work and i have noticed something.
On the way to work I travel inner city then highway..... no problems.
Going home is opposite.
Temps go up and down. Fans kick in fine and temps go back down.
As I get near home the ignition seems to play up and starts stuttering.
Cools down and is fine again.
Today it was warmer and traffic was heavier.
Stuttering down into dying.
If I hold the throttle on enough to keep running it would go up and down.
I am thinking it is possibly coil breaking down under prolonged heat.
Any thoughts?
The easiest way is to splash bucket of water to exhaust header and identify which cylinder exhaust dry up slowly.does it feel like it’s running on 3 cylinders when the stuttering begins? I diagnosed a bad ignition coil on a buddies bike once. the way I did it was a used an infrared thermometer and check the temperature of the exhaust tube coming out of the manifold. Once I found which cylinder was colder I switched ignition coils out with one of the other cylinders just to verify and it worked. Bad coil had to be replaced. also I think you can measure the resistance when it’s really hot and usually it’ll be out of spec.
Any idea on the voltage across the posts?I'm wondering if it could be an electrical generation or regulation issue. Can you check the input and output voltage of the regulator/rectifier?
