1977 KZ750 Coil Question

New member here, So thank you all in advance.

I just picked up a new to me KZ750, which was running a bit rough on idle, but WAS running just fine. Anyhow, it fell over on its side during the offload from the van and now it won't start. I'm not getting any spark, and have decided that as long as I'm replacing the spark plug wires and plugs (wires were looking really rough), I'll replace the original coil and do the WG coil mod.

My question is, what resistance is right for ordering new a new coil, am I correct in thinking 3ohm?

On a related but separate note, is there anything else I should trouble shoot that may have been knocked loose or broken from the tip over? I've started going through all the connections for the electrical, but it's a bit of a bird's nest, which makes for slow going. I'll also be replacing the points/condenser, as those were also looking pretty rough. Beyond that, I'll be at a bit of a loss if it still won't start- I find electricity to be a bit of a dark art in my view!

Thanks,

John

No, it's a four Ohm coil. Z1 Enterprises sells an OEM type replacement four Ohm coil for Kawis. I don't recommend using a 3 Ohm coil.

Check the kill switch on the handle bars and the lockout switch connected to the clutch lever. Either or both kill the ignition DEAD if the switch is closed.

Thanks! I've ordered the correct coil, along with some new points/condenser. I'll check the wiring for the kill switch and the clutch when I work on the bike again later this week. Hopefully I'll have her running before this weekend rolls around. I'll be sure to update and let everyone know.
