I took the carbs apart and didn’t find anything missing, if there was I’d have 3 in place and one not. 
im pretty sure it’s on the rack.

My mystery part is now on the main rack shaft where it belongs, I missed it when assembling. I love that spring!

My gauges returned from the Netherlands. Marcel does a wonderful job.My chrome is on the way back from SoCal. It will be busy soon.
im replacing the sprockets and I’ll be putting non ring 630 chain on. The old sprocket has some strange damage I suspect was caused by some sort of alignment issue. I won’t ever do enough miles to use the chain oil pump but I will install it.
does anyone have a photo of the chain oiler vent hose routing?
also, carb overflow lines, anyone have a photo? The bike came to me pretty incomplete so I’m not sure of the routing.
an example of how incomplete are the gauges. They are supposed to have a foam type layer between the gauge and the bracket. These had pasted together brown gasket pieces. Fun.

If you concerned about chain alignment check your front and rear sprockets, they either both need the O-Ring setup on non O-Ring. O-Ring setup up will have a shoulder on the front sprocket that is inward, and the rear will have a sheet metal ring between the sprocket and the carrier. The gauges look great would you share his contact. It’s a shame he eliminated the date stamp on the bottom shell. See included photo of the foam dampers that live between gauges and the bracket. Not sure if they are available but you will have the part numbers to search.

Yes, too bad about the date codes on the gauges.  As for the foam pieces, John Brookes makes them.  I purchased several from him.  Send him an email to see if he still has some.  If not, PM me and I can donate one set.
I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

OEM Z1 countershaft sprockets were flat.  Mama Kaw issued a shim for use on the flat countershaft sprockets, as well as the rear sprocket carrier to increase spacing when using O-ring chains on Z1's and Z1-A's.  Later countershaft sprockets were shouldered on one side to use with either type of chain.

Chain oil pumps relied on the pumped oil for internal lubrication.  If they're run dry they'll self-destruct.

The carb overflow hoses are bundled using a rubber 'band' (PN# 92037-134, parts manual Item # 61 in 'Frame') that has a loop at each end.  It wraps around the groove in the upper right motor mount collar (PN# 92027-160, parts manual Item #18 in 'Frame').  The bundled hoses then drop down between the motor case and the swingarm.  Let us know if you'd like a pic.  Won't be 'till tomorrow if needed.

The chain oil tank vent hose is surprisingly long.  It follows a circuitous route to the rear on the inner side of the the upper left frame tube to underneath the tailpiece, then curves to the right under the tailpiece just outside the turn signal/tail light wire bundles that are secured under the two steel tabs on top of the rear fender.  The vent tube continues curving right then forward, continuing forward along the inner side of the upper right frame tube under the tailpiece, then gently curves down, lying on the wide flange of the plastic inner fender just inside the frame tube. It ultimately terminates at the steel tab that secures the inner fender with the open end pointing forward  & down.  Complicated to describe in words.  We might be able to find an old graphic that depicts routing.

Good Ridin'

This is a link to where my gauges were done, it takes a bit of time, mine were about two months. Top drawer work. The gauges on my 73 CB750 were pretty rough, they are perfect now. I’ll post a photo of them. 

A problem I’ve been having with the Z1 is when I’m looking for some obscure part such as gauge lights, I’ll find a vendor and make the purchase and get a confirmation only to be told a day later they are refunding my purchase because they actually don’t have the part. I begin the search again. Z1 Enterprises, Z1Parts.net, Johnny’s Vintage and others are good sources but there are quite a few things for an early Z1 that are tough to locate as many of you know. 
For SOHC Honda fans there is Yamiya in Japan, David Silver Spares in the UK as well as several other sources that really have almost everything one might need to do a CB750 Honda unless you are doing an early sandcast K0 which was every bike below number 7414, then it gets a lot harder. I guess a Z1 made in 1972 is sort of the same but a bit harder.

Right now I’m looking for instrument lights, I have some on order but I think it may fall through. My old ones fell out. My fall back if I’m forced will be to adapt a set from a CB750 which are almost identical and easy to get, I think I may actually have a spare new set from my K3 750 project.

Funny, the 750 is actually factory candy blue green which is a 1970 model color. The green does not render at all and the bike looks blue in the post. It’s a bit greener in person.

I emailed John Brookes about the foam pieces behind the gauges.
