TOPIC:

Each of the shafts has two nylon pieces, one inside and one outside. 

This is slmjim.

That looks maddeningly familiar.

Is the ID the same as the long shaft (16041-004), #83 in the parts manual?  Does the OD match the bore where the shaft passes through the carb holder (16065-019) #88 in the parts manual?  Hard plastic or stiff-ish rubber (be gentle! It's old.)?

The only ribless carbs we have are installed & running on our 'The Seven Year _itch' early '72 Z1.  When I went through them after stumbling across them at Mid-Ohio, I noticed differences in the small parts on the shaft assy. that didn't precisely match the parts manual, a standalone parts sheet from an old OEM Z1 carb kit or, John's book.  I took pics during disassembly for use during reassembly.  I may still have them.  It'll be later today before I can look & will post tomorrow if located.

I checked with my buddy Kevin today and he said felt is the correct seal.  He thinks the felts may have been replaced.  He has felts on his restoration of 1006.

It fits nicely on the rack shaft. My parts manual doesn’t really show a part like this. Weird, I went through the rack and carbs and could not see anything missing. The carbs have been run too! 
my carbs did not have felts either.

I was going through some photos to check out some “as found” conditions and it’s a wonder I took this bike on, it was pretty ugly, as I imagine many here have encountered.

Working on my master cylinder and I’d like to verify the assembly order and orientation. Does this look correct?
the manual and parts manual are a little vague. 
thank you

You have to swap the rubber parts # 8 primary cup to piston and #10 check valve cup to spring end.

 

Thank you, I was wondering if I was seeing the manuals wrong. The illustrations aren't very good.
The FSM skips over a lot of details.

Sorry it took this long.  The prints were buried in a manual we haven't had out for over two years.  The pics were taken for our reference only & printed low-res on a B&W printer without ever planning to be made public.

In the parts manual we see #76 'COLLAR D' next to the long spring #75.  Below that is the carb rack itself, #88, and also #84 'COLLAR F'. There is no collar shown between the rack's left boss bore and #76 'COLLAR D'.  We believe the mystery collar is located between (inside) the boss and 'COLLAR D'.  Without disassembling the rack that's on our bike now, that's as close as we can come to recommending where the mystery collar belongs.  See pic below.

I do not know that this will be of any help but that part sort of looks like #66 in this pic from a Z1 manual?

That looks like it, I'll take the rack apart and check.
I checked the carbs, they are ok.
As I wait for chrome and other things I'm going through sub assemblies. Amazing how many little parts were missing on this bike. As an example, the small bushing in the clutch lever pivot was not there, instead of the bushing and a 5mm bolt it was just a 6 mm bolt.
The endless stream of small parts continues.

Indeed that does look similar!  Thanks for the suggestion.

We don't have any loose carbs at the moment we can disassemble to check.

MauiZ1, gd4now's suggestion might keep you from having to deal with those aggravating #*^& ! return springs.
