KZ1000 misfire and high RPM breaking up

If carbs are out of synch, you may have one cylinder just tagging along at idle, meaning you will not notice if you pull off a plug. But that doesn't explain high rpm issues.

so I think i might have got it. piggied 12v from another wire and ran it to the coils, replaced a fuse, and bench synced the carbs and it seems to have worked. runs on all 4 and seems to rev ok. true test is when i can get it on the highway. ill be back with the results

For anyone who might be unaware --

If not already doing, be sure power to coils is cut off while the engine isn't running or being started.

Power to the coils is supposed to be "switched", meaning switched ON and OFF by the bike's ignition switch.

Good Fortune!

Oh yeah sorry for not saying that, made sure it was switched, didn't want to burn those little guys up. haha

Fellow KZ pals,


I have been slowly cleaning and fixing my 1998 KZ1000P, Took so many parts off and much time lapse. Finally rode it today and had to have a trailer come get me. It had no power, spitting and sputtering. Ran perfect before stated working on it...lol Sit for 1 year in kitchen. Before that carbs synched etc...



The coil wires thing seems to be a problem. I found this site and this diagram on the string.. Then i found this wire diagram. Can someone please explain.

This message stings says coil on left side wires go to left side and such, but the micro fish says they cross?

thanks for anyhelp.

Left coil, bottom wire goes to Inner plug on left side. and left coil top goes to the inner plug on the right side???

Usually, the right coil will go on cylinder 1 and 4 and the left on 2 and 3, but can be the other way around sometimes. Regardless, they are always paired 2 and 3 for one coil and 1 and 4 for the other. That's because those cylinders move in parallel, and a waste spark (spark at every TDC) will give correct timing for them as pair.

And now to top off the discrpancies, i found an old pic of mine where it shows differcnt routing.....

1998 KZ1000P original parts, L and right coils. 4 plugs....

thanks

In case needed... Dynatek downloads

Could be DynaIII, have original ignition plate (points/coil) for quick swap out test....

Dyna III rotor advance installed and unit timed correctly to spec (Static and Dynamic)...

What plug wires are installed (solid core, suppression etc...)

Could be carbs but sounds more electrical/ignition break down to occur only at 6krpm...
Carbs sync'd to spec...

Take a look at your plugs, black soot/carbon build up,burning lean, insulators have splatter particles on them thus pre-ignition etc.....


In case need... Note confirm w/your manual for your year/model but 1976 KZ900 - 1980 KZ1000 should be close to same....

Rectifier/Regulator measurements to spec...

Interesting photos of the spark plugs, thanks
