What KZ900 Do I Have?

Frankly, (just my two cents) people get all excited just for the two characters- a "Z" and a "1"- myself included, I want a Z1 . The KZs were better all around bikes IMHO- thicker gauge tubing in the frame and swingarm is a trade off for having "only" 26mm carbs.

yeah but you dont get to add bull riding to your resume riding a kz! :woohoo:
compared to newer bikes all the z1/kz series bikes are bulls wrapped in a glorified water pipe frame,the z1 was just a meaner bull to stay on the full 9 seconds! :woohoo:

So what would that make the H2 Mach IV 750?

Being as the Engine is Z1E 092120 did it come with 28s or 26s? Is there a way to find out? It has after market smoothbore 29 carbs on it now. What would be the difference between a Z1 Motor and a KZ? Aside from the collector value of a Z1 what makes it superior to a KZ?
Thans again for all of your posts.

Also when did the first bike come out of the Lincoln Factory and how many were produced in 1975? Does anybody have a lower KZ900-A4 serial# than this ZIF-500360? Were any of the lower numbers LTDs?

It came with Mikuni VM26 round slide carbs that did not have an accelerator pump.

Is there a visible difference between a Z1 motor and a KZ motor?

I believe they are almost identical with a few minor changes. Jeff @ Z1E has great knowledge about the differenes as well as, I'm sure, others on this site. My guess is you have a Kz900 engine, but again, I don't know that there is much difference in the engine.

Interesting thread. After reading your question about the lower serial number, I checked mine;
Z1F-099032.
According to one of the earlier replies, I guess that would make mine the 32nd bike produced that year?
(I have a '76 KZ900, not LTD)

Thanks for the info guys.

That frame number doesn't match a Kz900 frame made in the US, so I don't think the same applies. It actually looks like an early Z1 frame number, so I wonder how accurate that is - especially since you have 6 numbers after the dash instead of 5. Maybe you meant Z1F-99032? That would be a mid-range Kz900 manufactured in Japan.

Double Dub,
Just checked my frame, numbers are correct & match the sticker on the neck too.

Took a quick look at the link, & you appear to have a point. Oddly, the Z1 site starts the six digit numbers at Z1F-500001 Mine is lower (099032).
The engine numbers appear to be inline with Z1's site being higher (Z1E-107101) although not within 200.
Not tryin' to hijack the thread, but now you got me thinkin'.
