I just purchased a Kat - non runner with no spark.
I removed the carbs because they always need cleaning when they sit that long and I need some help to get some spark.
A few days ago I had some dull/dim but blue spark and when I tried to run the bike after installing the carbs I didn't hear it fire once.
So here I am now removing the plugs and plug wires and checking for spark again.
I tried checking ac & dc voltage off the alternator and I got nothing but I may have been doing it wrong now that I have read more.
Next time Im checking from the red wire to ground if I have any voltage generating but besides the point
It could be the pickup(s?) on the crankshaft. its probably not the Ignition Coils.
What else is there to check.
Does the AC Generator produce the signal and power going to the coils also or does that come from the battery? e.g. bike will run without an alternator albeit not very long
Also my carburetors had a couple issues...
The 2 jump tubes by the vacuum/cv slides in between the outside and middle carb are 'rotted off'
They Tee into both carburetors but the ends where a hose should go has rotted out. It is like a Tee.
hose #6
Also missing the spring adapter that goes over the needle so the spring isn't pushing on the slide
Part #8 on the picture
part # 13382-42A00
Then I found under the pilot air screw that one of the rubber washers was missing where the spring, then a small metal washer sandwiches in between the carburetor.
Just an observation.
