I have an 83 ZN 1300, I am trying to see if the throttle position sensor is common to any other bikes, is it common to the GPZ 1100, is it common to the KZ 1300, I would appreciate some feedback from those much wiser than myself. Thank you.

I use Partzilla for referencing information on parts. According to Partzilla, there are a number of different Kawasaki Models and years that the part #21176-1004  was used on see Screen shots I've included

What I would really like to say, is the throttle position sensor is nothing more than a variable potentiometer. Basically it's a stainless steel wire of a certain gauge wrapped around a non-conductive board. At each end of the wire is attached a lead wire. then there is a contact shoe that rides on the wire and it's attached to a third lead. if you attach a Ohm meter to one end of the stainless wire lead and the other to the contact shoe lead, you can move the  pivot and watch the resistance go up as the contact shoe moves away from th eend that the stainless wire lead is attached to.
The other end of the stainless wire has a lead and if you attach the Ohm meter to that end and leave the one end of the Ohm meter attached to the contact shoe lead, you 'll see the same thing happen. So you can appreciate that as the one outboard end increases in resistance, the other outboard end decreases in resistance. The engine management system will see the difference in the 2 resistances and change the fuel injection on time based on the resistance reported by the TPS.
Over the past 8 years , 2 or 3 of our members have pulled the TPS apart and cleaned repaired the TPS. It's not rocket science. It's a simple mechanical potentiometer..
Have a crack at a repair. Pretty straight forward.
Also, another place you'll find a variable potentiometer is the fuel tank fuel level sensor. Same operation, same repair. Not rocket science.

Good Luck, but you won't need it. If the wire is broken, measure the wire diameter and counts the number of wraps (coils) and just rewind with new 304 stainless wire of the same gauge.

Post note -  Now I'm starting to wonder if this throttle position sensor is a carbon potentiometer after looking at a blow up of your picture. If it is and the carbon is worn through, I'm not aware of any fix for that type. Not saying that there's no fix, just not that I'm aware of.
