Just clean the contacts with fine emery Arno and bend the contacts gently so they meet properly and have a little more pressure on them. That should be ok for the next 100,000 km.

He said he sees the click stuff all the time and it’s usually a starter he said. Never worked on these of course. I am inclined to believe MODVRS above that the solenoid could be bad. Or I increasingly wonder about the starter relay as there is a ton of stuff on the net of this easy fix to the click mystery. Where the hell is the starter relay on a KZJ78? Anyone know? there is no black box near the single battery. But a wire does come off the terminal and go to a device kinda in the firewall.Do you know what is wrong with the starter? Maybe there is an opportunity to rebuilding it / having it rebuilt?
