1973 Z1 rebuild

I can start fitting some of the chrome parts - the rear engine mounts and spacers go on, and I even put the original rubber overflow tubes holder on.

 

The powdercoated short side stand I made goes on with the chrome bolt and spring.

+1 - It's just a basic plunger switch

I made a bracket for the new horn, gave it a paint and fitted up.

 

bolted on the front mudguard too

 

Got another package from Webike, which really means just a bunch of new jobs to do 
new tank cap, new sidecover badges, ducktail install kit, gear shift rubber, a rocker cover gasket (that is rubber with steel centre, but not as thick as I would have liked), Blinker stem rubbers, headlight hole cover, battery holder rubbers, tank rubber strap and a set of rocker cover bolts.
i am hoping that will be the last big order of parts for this bike.

 

This build is moving along nicely, not long now and you will something you can truly be proud of   The original was nice but "of it's time" (IMHO) now it will be "timeless"

That horn bracket is where the oil cooler was designed to fit.  They had issues with frame cracks that started at those holes.  It looks like the right one (From driver position) in the horn photo was beginning to crack.  I had a Z1B where the crack moved into the frame tube and almost circled it.

Yep, I can see that also. But there is a second brace on the photo. How is that one connected to the frame? My Z1B has that problem too, in the past

So is the solution to drill a hole at the end of the crack (remove the stress point) and then weld it up ?

The solution KHI came up with for older bikes was to bolt a brace across from hole to hole, just as blackozvet has done.  From about Jan 75 onwards they eliminated the oil cooler bolt holes, which were the stress concentrator.  The KZ 900's had re-designed braces.

Some photos of cracks on a frame of a bike I purchased. The frame was repaired during restoration.

I have welded a brace across the frame at that point.

Now when your doing a project sometimes you go for some low hanging fruit to get a feeling of success, you know that 10 minute job just to finish something off.
And that 10 minute job turns to shit 
I went to clip the Doremi brand sidecover badges on - and the front studs on each one are too short to get the clips on.  they have a thin piece to guide thru the hole then a fat piece for the clip to tighten over.  The fat piece barely goes thru the hole, certainly not enough for the clip to grab hold of.
I tried cleaning up the inside of the surface but it didnt help - not too keen on getting too carried away on the new sidecovers.
not happy.

 

Might be easier to use the 3m emblem tape, it was posted on another thread.
