Z1 or KZ900A4 ???????

Ok, I recently scored a "76" Z1F. I am informed that in 76 there was no Z1, only KZ. This bike has always been titled as a 76 KZ900A4. Tonight I was talking with a guy and forgot whether it was a 75 or 76, so I looked on the framehead above the v.i.n.(which by the way is Z1F-088237), and it says that the vehicle conforms to 1975 model year blah,blah..... My question is: Is this one of the last Z1s????? Do I have something here that I should tread lightly on as far as mods etc...???? Or is it just another old KZ????? :blink:

Generally anything built in middle of year is considered the next model year,from your picture the paint/bodywork looks like a 76 kz900 to me anyway.
Does the battery come out through the right side cover? that would make it a 76 kz900

It's an early 900A4. Frame numbers started around the 85*** point.
