Changed the spark plugs, now it won't start
« on: February 22, 2018, 03:27:37 am »
Boy oh boy I hope somebody here can offer an idea on this one...

Buddy's Kawi Z750S. Or Z750, this one is a '05.

I rode it around, got the engine hot and then did an oil change. It ran fine. Started it after changing the oil, no problem.

Then I changed the spark plugs, and now it won't start. Starter spins and engine is turning over, but no spark.
These are stick coils and they are an absolute bear to get at. The entire front of the wiring harness has to be pulled through the frame to behind where the coils are. I MUST have pulled a wire loose but I can't find anything anywhere. There's voltage at every point in every connector.

So...anybody ever heard about a mysterious 6v gray wire on some of these Kawis? Cuz this one has 10 volts and I can't find out if this bike has that resistor system or not.

Is there any chance I've triggered some kind of anti theft system?

Already jumped the clutch and side stand switches. I can't think of anything else.

Are the plugs the same as the old ones? Did you actually check for spark at the plug, or are you assuming no spark because it won't fire? Have you tried starting fluid to see if it will fire on that? Are the carbs getting fuel... Does the bike have a vacuum petcock, maybe it needs to be on prime?

Engine kill switch on?

Other than that, I agree, you must have pulled a wire out of a connector... Perhaps pulled partially out an individual, it looks like it is in the connector, but not making contact.

I don't know anything specific about that bike so I can't answer your questions about a 6V or 10V wire, or any security system.

I finally found a wonky wire near the cam position sensor. Now to button it all back up, again, and see if there's spark.
