That spring is for the caps used on the 74-75 tanks that were also used on some of the H1, H2, S3, Z1 and others which looks like this:


The 76-78 used a different style of cap that mounted differently to the tank and looks like this:

I ran into this a few weeks ago when I put a 75 tank on my 76 and thought I was going to just simply swap over the fuel caps. That's when I realized they were different and had to order a new one.

If it is the older style cap then it is a bit of a pain in the butt to hold that spring in place with tension with the cap and tap the pin that holds it all together at the same time. Once you figure out how the spring needs to be oriented to apply the proper tension you're well on your way. I used a small screwdriver to hold it roughly in place along while using a punch of a smaller diameter in place of the capture pin. Then I tapped the pin in from the other side replacing the punch as it was tapped through. I know that may be difficult to visualize without seeing it. Hopefully I explained it well enough. If not let me know and I'll try again.

Without seeing what you have, or knowing what cap/tank and year bike you have I can't give a definite answer.

But I will say a tank swap is your second best bet, your best is making your cap setup work because you probably can't just swap caps out. And the locking caps on KZs are actually quite annoying as well

The feet, or the 2 straight arms off of the loop....one arm lays down flat on the tank, and the other arm will locate up into the notch in the latch.

More moving parts, not keyed, can get to be sticky.
Z1 style is just simpler
