Looks nice and shiny!  The swingarm bolt is backwards.

Don't see any mention of VIN or "born with" motor?  Would be interested in how close the numbers are to each other.

As usual, I am awaiting MIKAW's assessment of this bike to find 20 items that I never would have seen! 

There are quite a few things that are not OEM.  For example, the needles on the speedo and tach should not be red tipped.  The nuts and bolts look to have been vapour blasted.  Controls are plastic replicas.  The warranty sticker on the right side of the ducktail shouldn't be there.  Warranty chains were only supplied to the first 6,000 Z1's.  Not to Z1A's.  The red reflectors on the shocks are not OEM.  Likely the shocks themselves are repro.  But....overall the builder stayed pretty close to the original bike in appearance.  

I also noticed in the ad description it says 1015 CC's so possibly a later KZ1000 motor?

It looks like the engine parts like head nuts, valve cover, etc are 900 so I'm guessing it's bored to 1015.  I restored one that was bored out but I returned it to 903 cc.  I still have the bored cylinders.  Hard to slip on the pistons because the taper on the bottom of the cylinders is almost gone.

There were 2 1975 Z1s in the recent Shannons Auction in Australia.
One went for $27,222 AUD (non matching numbers engine/frame)
One went for $29,500 AUD (numbers not quoted in description) (had Euro rear mudguard so could be import)

 

I emailed the guy about the bike and he gave me the numbers from frame and engine.  It appears to be within about 100 digits of each other so seems like it could be original motor to bike.
He also said that the jugs were bored to 1015 which would confirm Hardrockminer's earlier comment.
