Faults:

Nothing to report so far. It's reliable and runs great.

Cam chain tensioner has not been replaced, though I'm considering it.

Initially, one cylinder was dead or mis-firing. But this cleared up on it's own after a bit of driving.

Bike was imported in (used) from South Africa, so this is German/European Z1300 model (but without the HP limitation). It was obviously well maintained and in 'high speed open road tune' from all those South African bush roads when I took ownership.

General Comments:

Overall, this is an amazing machine, even to this day. It's big, comfortable, torquey, reliable, SMOOTH and fast... in a subtlety understated way. It comes on like a freight train, and is rock steady on the interstate. Seemingly impervious to cross winds, gusts and semi truck bow waves. But it is surprisingly nimble and a good handler -- for it's size and weight. Quiet too... a bit too quiet... but with a NICE muffled powerful sound. Not a 'flashy' six like the CBX or Benelli Sei. Probably that's why it didn't sell well. How would you type cast or position/market this bike? It's in an unique category of it's own.

I still can't believe these didn't sell better back in the day. It's much 'better' (IMHO) than Honda CBX or original Bennelli 750 Sei (which I also own). Water cooled, longer stroke, shaft drive and 3 into 2 carbs make it much more civilized, quiet and less frenetic than CBX. But it has big power rush just the same and it doesn't seem to make a difference which gear you're in... :-) Only wish it was made with 6 speed tranny instead of 5 speed as it has the power and legs to support an 'overdrive' gear in the top end. Kawasaki missed an opportunity there I think...6 cyl, 3 carb, 6 speed. :-) Agree with comment about running hot in traffic though...

Sure it's big and heavy. Sure newer bikes w/much smaller engines wax it. Who cares? For comfort on high way AND backroads -- this bike does it all. And with great ergonomics, comfort and a 'secure' and stable feeling. Gas mileage is directly proportional to how hard you push it. I get between 30 to 38 MPG... so what's wrong with that? No wonder it became the Voyager. Definitely a GT bike. Find a good one though!!! Sorting out anything on this bike will cost you many pretty pennies. PS... mine is NOT for sale. :-)

Faults:

Ignition coils go bad as early as 7000 miles.

Cam chain tensioner is prone to failure.

Electric gas shutoff valve causes fuel starvation.

Some 79/80 model bikes had high oil consumption from out of round bores.

Mechanical ignition advance sticks.

Nylon cam chain idler gear wears out by 40k miles.

Oil starvation problems from too small of an oil sump.

Prone to hydraulic lock of gas boils out of carbs while bike is sitting on the sidestand.

Can overheat in traffic easily.

General Comments:

Overall this is on of the best bikes from the era for long distance riding. It's not an around town bike. You don't want to get stuck in traffic with it because the watercooled inline 6cyl motor puts out an immense amount of heat. Even while riding, the heat coming up under the gas tank can give you what we call 'lobster legs'.

King & Queen seats were real popular because the original seat wasn't all that comfortable. The other issue with the seat was that you could slide back on it under full throttle. This was an issue for the passenger if they weren't holding on tight.

Because of the width of the motor, you could drag the cases in the corners pretty easily. The bike handled real well, even at high speed, but you had to be careful not to bottom out in the curves.
