PRODUCT OR SERVICE ADVERTISING IS STRICTLY LIMITED
KZrider is more than a website. Its members comprise a community of KZ enthusiasts dedicated to encouraging and preserving our sport and passion for Kawasaki Z, Z1 and KZ motorcycles. We pursue our passion because we enjoy it, not to make money from it. To that end KZrider.com is not a place for you to solicit sales of any kind. No member is allowed to refer to their own business, or any business to which he/she is associated, through the discussion forum or personal messaging system (U2U). Be aware, the U2U feature has been abused in the past. If any member solicits an unwelcomed solicitation through the U2U system please report that solicitation to the Administrator or Moderators promptly.

There are four exceptions to this policy:
1. As permitted in Classifieds (consumer-to-consumer transactions).
2. An item may be offered for sale as a consumer-to-consumer transaction in any forum where there exists reasonable expectation of being welcomed by another member who has previously posted in the thread ("cold calls" and "door-to-door" solicitations are prohibited).
3. Each member is allowed a simple link (somesite.com) in their signature, which link shall include no description of any kind.
4. Paying advertisers are allowed to post in the Vendor forum.

KEEP IT CLEAN
You may not post libelous or defamatory messages or materials, or include links to such materials in your postings. You may not post messages that are obscene, violent, abusive or designed to harass or intimidate another individual. Pornography, Warez, or any other illegal transactions may not be posted or included in members profiles. No blatant nudity.

BE CIVILIZED
Don't use racial, ethnic, or gender slurs, religiously derogatory comments or any other personal discriminations even in jest. Use of slurs needlessly offends people - whether or not they're a member of the group you've insulted. Respect others' religious beliefs and culture. Recognize that others have religious and personal beliefs which may differ from yours. Stay away from political debates. Keep the language and behaviour appropriate.

USE DESCRIPTIVE THREAD TITLES
When you post a new thread, please give users some idea of what it contains in the title. Thread titles like "Help" or "Check this out!" are cheap ways of getting users to look at a thread they might not care about, and would not have clicked on had the full title "Help, I need credit card numbers!" been used. Furthermore, it helps stop multiple threads on the same subject. When starting a new thread, describe the content of your thread clearly in the 'Subject' line of your post. Don't use vague subjects. Use descriptive and specific subject lines. This helps others decide whether your particular words of wisdom relate to a topic they care about. For example: "HELP!!" is not an appropriate subject and neither is "My bike doesn't run".

PLEASE DON'T SHOUT!
That cap lock key wasn't invented to help you get your message across. Messages written in all caps are annoying, hard to read, and loud.

HAS IT BEEN POSTED ALREADY?
Please look for an existing thread on a subject before you post one about it. Chances are good that your question has already been answered. There is a search feature on these forums, use it. Starting topics that have already been answered in great detail is a waste of everyone's time. Look to see if information you're about to post has just been posted by someone else. Then go ahead and post.

WE HAVE SECTIONS FOR A REASON
The Technical Forums have different sections for a reason. If you're not sure, use your best judgment. 

DON'T CROSS-POST
Cross-posting is when you post the same message multiple times in various threads or forums. We only need to see it once guys. 

STAY ON TOPIC
Keep threads on topic. If you've got something completely unrelated to say then start a new thread. Unresponsive solicitations for consumer-to-consumer sale are prohibited as being unrelated and off topic, but solicitations for consumer-to-consumer sale may be posted in Classifieds.

CONSIDER THE IMPACT OF YOUR WORDS BEFORE POSTING
Adhere to the same high standards (or higher) of behaviour online that you follow in real life. In real life, most people are fairly polite and law abiding. The same rules of behaviour are expected on any list.

MESSAGES SHOULD CONTRIBUTE TO THE TOPIC BEING DISCUSSED
or introduce a relevant idea. If you've read enough threads, you've already learned how annoying it is to go through "Me Too" posts. A "Me Too" is a post that says "I agree with what the other guy said" and otherwise does not add to the content. If you have a comment about someone else's post, tell them via U2U or email. Generally speaking, unless it concerns the entire group and is within the group's stated purpose, you should reply only to the author. Avoid replies or responses to the whole list of yes, no, or "I agree!". This is meaningless and you too would be annoyed to open such a message.

WELCOME TO KZRIDER
If you are a new member, introduce yourself by posting to the New Member Forum. While it's nice to welcome a new member, only do so if they have posted in the New Members forum. There is no need for 50 welcome posts in a technical forum thread.

U2U IS A WONDERFUL FEATURE
Please don't start a topic that is directed at one person that could be put into a U2U to them. If you have a message for one or two posters, use U2U or email.

According to Kawasaki, in the U.S., the KZ400 A1 is a 1977 model.

The 1976 models were S2 (special) and D3 (standard) models only.

In 1977 there was an A1 (deluxe), S3 (special), and a D4 (standard).

Up to 1977 all carbs were piston type CV.

In 1977, the S and D got diaphragm type CV while the A got piston type CV.

In 1978, the B1 took over as the "Standard", and it had diaphragm CV. And the C1 took over as the "Special", and it also had diaphragm carbs. The A2 (deluxe) changed over to diaphragm CV carbs also.

The 1979 H1 (Ltd) along with B2 (standard), had diaphragm CV carbs.

So, it will depend on what year/model the engine is from to know what holders to get, and I'm not even sure which models use which size because Kawasaki.com seems to be inconsistent. There are apparently 3 part numbers:
16065-037
16065-048
16065-1002

I've made some holders for the piston carbs. Here are the dimensions I came up with.
It's for a 76 S2 and a 75 D2, which according to Kawasaki.com is the same holder on a 77 A1, but that is not absolute, especially since the later D models show a different number. It's all very confusing.

I then attached the carbs with a section of heater hose. It's ugly, but worked great.

Alright. After a couple hours of diggin, here's what I have, but it doesn't really make total sense since the D3 and D4 use different carbs, but show the same carb holders...not impossible, but I wouldn't think it likely since the carbs are so different. Will have to investigate further later.

1974 D1 (Standard) : piston CV with 16065-037

1975 D2 (Standard) : piston CV with 16065-037
1975 S1 (Special) : piston CV with 16065-037

1976 D3 (Sandard) : piston CV with 16065-048
1976 S2 (Special) : piston CV with 16065-037

1977 A1 (Deluxe) : piston CV with 16065-037
1977 D4 (Standard) : diaphragm CV with 16065-048
1977 S3 (Special) : diaphragm CV with 16065-037

1978 A2 (Deluxe) : diaphragm CV with 16065-037
1978 B1 (Standard) : diaphragm CV with 16065-1002
1978 C1 (Special): diaphragm CV with 16065-1002

1979 B2 (Standard) : diaphragm CV with 16065-1002
1979 H1 (Ltd) : diaphragm CV with 16065-1002

I hear your pain. Been through it a couple times.

If the bobber has a front disk brake and electric start, then it is likely a 76 D3.

The 76 S2 had drum in front, no electric starter, and I think no tach.

The D3 is listed as having different holders than the S2 or the A1. I can't imagine what the difference would be since the D3 and A1 use the same carb rack. Maybe the motors are different.

But just a heads up that you may actually have to seek out two different sets of holders.

The bobber is a d3 I now remember that from the original owners manual that I lost!! The carbs are thesame cause I mismatched them together. So that means 037 and 048 are NOT the same....both no longer available also. This sucks big time!!!

:unsure: height??

Holes in a carb holder must match mounting studs on the engine head (center-to-center distance between studs should equal center-to-center distance between holes in carb holder).

Inside diameter of the holder must be sufficiently adjustable in order to snugly tighten around the outside diameter of the carb.

:unsure: What is center-to-center distance on the bike at hand (to compare with the information furnished in the ad)?

Good Fortune! :)

Also, notice the center-to-center line of the mounting holes is offset by 3mm from the center of the bore. (in the diagram I posted)

Wonder how tall are the oem carb holders?

Wonder if the ebay carb holder has sufficient distance between the mount holes (appears to need an additional 1.3 mm), or enough material to elongate each hole?

loucarbholderflangediy.jpg


loucarbholdercenterlineoffsetdrop.jpg


Wonder if the ebay holder has the needed 3mm offset below center-line between mount holes?

Unfortunately, the drawings of Mikuni's offerings appear not to have the needed 3mm offset below center-line between mount holes.

Good Fortune! :)

Any details available as to diy construction of the metal flange?

And source/type of sufficiently large "heater" hose?

Good Fortune! :)
