Re: 1979 CBX 1000Z - Time to put it back together...
Mike,
The post office here is like the 405 freeway at 5:00 PM I can ship a larger package Priority Mail and print and pay for the labels from home. International or Domestic does not matter. Then all I must do is to drop it off at the P.O., no waiting in line. I can't fit a large label on a small package and I don't know how to do it with first class mail for an international shipment. I have a good postal scale so figuring the weight is no problem. Sad because I have enough 31mm springs to give one to Paul.
Best,
Phil

It looks like I can ship it Priority Mail for $25.00 and change.

Phil,
Lets see if I can get one in Europe - but not sure it will be any less than the $25!
Really appreciate you offering to help.

CMS does not show it available, but the list price was 7 Euro.

Paul, that price is for a small flat rate box. There is room in it for other small parts.
Just let me know

Mike,
I don't think that they have been available from Mother Honda for a long time. The one I am offering is used but 31mm in length. I do have a couple of NOS ones for personal use.
I heard recently that the A&B clutch plates were sold recently for $300.00 I guess that used parts are harder to come by in the UK ?

Carbs
Not finished the carbs yet, but here is where I am now.
Given the bike had been standing for some time, the carbs were a problem - every single jet / passageway was gummed up.
A few highlights:
- I stripped the carbs, including taking out the throttle plates, and had them vapour blasted. There were a couple of linkages on carbs 3 and 4 I didn't take off - seemed to be a press fit of some kind so left them on (vapour blast didn't affect them)
- All the mounting brackets were zinc plated
- Slow jets taken out using #2-56 machine screw, didn't need to drill / tap the jet itself
- Used Mike Nixon's book which was very helpful.
- Used carb kit from OldSchoolsCarbs - had every thing I needed including fasteners (bought the throttle plate screws and felt washers aswell)
- During reassembly, had a problem with a couple of the choke plate screws binding. I didn't follow Mike's instructions to tap them first, and it caught me out!
- Accelerator pump jets were a pain. They were cleared, then they were blocked, then cleared them again. Still not sure they will remain clear - we'll see
Some pictures: The (almost finished) carbs:
Thought I had finished, so filled with petrol to check for leaks in prep for putting back on bike. Not just a drip, but petrol pouring out of all 6 overflow pipes!
Not sure what it is yet:
- I had cleaned and checked float valves / heights
- Having taken them apart again, noticed that on two of the valves the spring on the top is locked solid. Obviously need to fix that, but would that in itself cause the leak?
- no other obvious problem, but will clean everything again and try again
- Anything I should be looking out for which normally would cause a leak like this?

Carbs look great, Paul.
Perhaps have a close look at the standpipes in the float bowls. They tend to crack and leak fuel.

Paul, Tony Herd, aka "herdygerdy" developed a very slick technique for unblocking the accelerator pump with hydraulic pressure, I'm certain it's here somewhere. It is very clever. Let me see if I can find it...

Re: 1979 CBX 1000Z - Time to put it back together...
The accelerator pump nozzles will often 'glaze over' from the cleaning process before you actually get them into service. Put everything together except bowl #3. Just before installing that one, spray brake cleaner(not carb cleaner) into the accelerator pump circuit. Whether it comes out all six is not important. Now blow high-pressure air through the system at the inlet from #3. Observe cleaner spraying from all nozzles now. Blow until nothing more comes out. Brake cleaner leaves the least residue. Should be good to go until wet testing them on the bench. After the bowls fill, operate the throttle several times to observe gas pumping out all 6 nozzles. Sometimes the system is hard to prime - if so, just grasp the pump shaft with needle-nose pliers and give it a few good strokes - it will begin pumping then.
Yes, stuck float springs are bad - the needle will not seal. Those have to be completely free and snap right out when depressed. That's at least one of your problems. Are you positive you installed the floats right-side-up? It's easy to get them wrong and they'll way overflow the bowls. Cracked standpipes are also common.
