First time owner of a KZ750

I'm 49 and can't beleive I have never owned a any KZ! I bought a 78 KZ 750 twin a few days ago. Ran great. Got home and washed it. Now no spark! Dried out for 3 days now and no start. Bummer. What could it be? Bad coil? Thanks

Bad coil, points gunked up with whatever crud you washed off or coroded connections.

Not a bad looking bike; had a 76 750 twin, was not a bad running bike, wasn't easy on starters though

Would first check -- with ignition switched ON, is full battery voltage being received at the ignition coil primary terminal (where likely a red or red/yellow wire feeds into the coil)?





Good Fortune!

Check your primary fuse and wire. Happnened to me once after taking of the side panel. The wire and orange coming off the primary fuse going to the battery with a bullet connector in between that got disconnected. Might check the fuses as well.
