what model is this tacho off?

The Tacho on the left is an original 1977 KZ650B1 tacho,
I thought the one on the right was the same, but its different, either its off a different model, or they forgot to dip the needle on the accasional friday arvo:laugh:

The tach on the left is KZ650. All KZ650's had the orange tipped needle.

The tach on the right is KZ900.

Both are identical internally.
