lost spark

i have a 1980 ltd 1000 with <10000 miles. bike runs great and then i lose spark to cyls. 1&4. if i pull plug wire on #4 and hook up and ground to engine another plug while bike is running #1 cyl. will pick up and i get spark to #4. when i switched coil 1&4 to 2&3 problem stayed with 1&4 cyl. coils as well as igniter check out within specs using ohmeter. i was told the p/u coils may be bad. does anyone have a set for a cheap price or i have other kz parts like handle bar light switches and parts for kz1000,gauge cluster for kz440 4ohm coils and k/n pods for kz650 to trade.
thanks,
dave

Any answers yet? Did you get her fixed?

dadoo, welcome to the KZR nation. Great to have you here.

IMHO, you could use the 4 Ohm Coils you have for trade... if they fit mechanically.

Points ignition systems usually call for 5 Ohm Coil(s) and my Dyna S Electronic Ignition system calls for 3 Ohm(s)... so at 4 Ohms you are kind of in the middle.

The points should wear out just a little faster and the e-ignition should produce a little less spark but this could be a work-around solution that gets you on the road now. Then you can implement a longer term solution over the winter months.

Best of success.

I believe the Kawi OEM coils for points ignition are four Ohms. That's what mine is. A four or five Ohm coil should work fine. Z1 sells the OEM replacement four Ohm coils for $36.

However, since you said:

when i switched coil 1&4 to 2&3 problem stayed with 1&4 cyl.

It probably is not the coil.

the ignition coils check out fine. what i was told i may need are the eletronic ignition pick up coils. have'nt had time to mess with this past weekend, maybe tomorrow.
thanks for everyones input.
