Confirm Tachometer cable length

Odd question, but could someone confirm the length of a KZ900/Z1 tachometer cable for me?

I have a KZ650 tach cable on the bike and confirmed it is about 26-1/4" + (measured on bike) The current cable is at its limit fit wise because it has to route under a big oil cooler. I was hoping a Z1 cable might be slightly longer.

The two cable part numbers say they only fit those bikes, KZ650/KZ750-4 or KZ900/Z1/KZ1000. I am getting conflicting results when looking up online saying they are interchangeable.

Hey, Injected. If you can wait, I'll measure mine this weekend and let you know.

I can wait, its on there and working, but its not optimal. Its not going to stop me building and starting the engine.

Thanks.

My old one looks to be 26/1/4". It's aftermarket.

Well that confirms they are the same length as the 650/750 part. I was hoping they were longer but its not a big deal, will just use whats on there.
