This is the Z1R-TC I had and sold to the previous owner of the H2. Dropped a valve in 1980 at 1300 miles and taken apart. Sat in boxes until 11/09 when I bought it. Completely redone with 1200cc low comp piston/bore kit and new everything.

Original paint with the exceptions of the sidecovers and front fender. Not done to 100% original but pretty darn nice all things considered. Scary to ride.

Oiler routed proper now. This 'site is already saving me big time

Who does make occasional mistakes when posting after a 500 mile delivery day . . Oh, and a glass of wine . . . or Three! - In that the bike is a 1971 model, not 1972 as I suggested
.
Jim, The early 1971 Models all had the "torx" stamping in the caliper bolts, also the super early bolts were also zinc an passivate plated as opposed to bright Zinc
.
Kie, I wouldn't want to ruin your day with a list of the faults that are on the bike, mostly minor such as Exhaust clamp clips missing, fuel pipe clips missing, petrol clips missing, black brake fittings, wrong fuel tap lever, brake disc bolt lock tabs missing Etc Etc Etc . . Blah . . Blah . . Blah . . . NOTHING that detracts from it being a lovely bike Lets move on to the Turbo LOVED Mine to bits and the sale of my own bike pushed the prices to the present limits on Ebay they never went above $8,000 before I listed my own and it sold for $20,000 - then after that the prices just went up!

You mean like this? It looks like a Torx, and a torx driver will fit in it, but it's just the material that was displaced when the hex was broached. You can see space behind the metal at the back of the hex. I understand that later bolts didn't look like this. The one in the photo is on my H2, serial 43xx. The ones from my parts H2, serial 18,xxx were made differently and are clean at the bottom. I was just pointing out that this was not an intentional Torx stamping, but a by-product.

Those were your vids? Watched them many times. Small world!

Don't worry about ruining my day, no chance. I've been doing this too long to stress about incorrect details on a 40 year old big-kids toy.

I have you to thank for the 'TC seller's market? Much obliged! I thought a $30k starting point would induce much sphincter clenching and other untoward behavior but my buyer sailed right through the storm unimpeded. lol.

Yep, you are totally correct, just another note in the book for those of us that are "anal" about the subject, You will see in the first prototypes that the bolts were also gold passivate plated, I always thought that this was airbrushed in on the photo . . . until recently when I started study VERY early H2's in depth .. .. .. I did look for the piccy from the cover of the Kawasaki Magazine . . .but can't find it at present .

I don't have the luxury of having a bolt in front of me but that torx shape almost looks too perfect to be just displaced material IMO... Normally the head and hex of a socket head cap screw are cold headed, not broached.
I have seen broached hex's before but there is evidence of the broached material smashed in the bottom of the hex.

Andrew, I'm certain it's just displaced material, because it's a thin piece with air space behind it. Notice the points of the star align with where the least material was displaced to make the hex.

The end of the hex (after broaching) depends how the pre-hole is made, either drilled or machined

Of course you are right Jim if there is a cavity behind the "torx face" I should have known better... Lol
They must have broached that hex at allot higher temperature than what I'm used to seeing...
Here's an example I found to compare the cold broached as opposed to cold headed...
