Throttle question

I was out on my KZ1000 this evening and noticed that the throttle has a lot of free turn in it before it catches. It has full throttle range once it catches but it has about 1/4 turn in the throttle before. It hasnt had this. Could something be out of adjustment? If so how do i readjust it? I have it listed on Ebay and need it fixed.

check the cable on the carbs,sounds stretched

Thanks Plummen, if it is stretched can it be adjusted out? If not will the cable from 76 KZ900 fit it to replace it with?

cables from 73z1 through 80mkII should be pretty close i believe,ltd cables might be a little longer

New cables are only about $15 each so I ordered 2 new ones to replace both push and pull cables. I was looking through my Clymer manual to see how to change them and I have to say that manual is about useless. It had nothing on changing out my cables. Anyone have a diagram on this or a link to a site that explains it?
