So I recently took my '83 KZ700A1 out of storage and need to fix its very weak starter before using it and I was hoping someone could give me some hints..
I have pulled the cables from the battery (they look fine in both ends) and swapped the battery out with a new one but that made no difference. It is still very weak and can only start once or twice on a full battery (still plenty of power left if measured). I fixed the poor start of the old Suzuki GS450S by ordering a starter repair kit on advice from a Suzuki mechanic but I'm not seeing any kit for the KZ700/750 the places I normally order from. Anyone know what I should order or maybe more important how to find out what needs to be swapped out?

voltages should be within 0.5V of each other
Voltage should be at least 9.5 V
if both below 9.5v-battery is the problem
if both voltages are different by more than 0.5v-cable issue
if both voltages are within 0.5V and you still have the issue---the starter is the issue
