70s 4stroke Kawasaki parts interchangability

[classicman]

how interchangeable are the MC and caliper repair kits between Z650's?
Sorry, I'm not sure what model z650 brakes are from

[Gosling1]

these can vary a lot - you need to know the exact model. Early 650's used calipers that are pretty similiar to the calipers used on 76 z900's and 77-80 Z1000's. 650's changed their caliper style to the GPz-style caliper around 1980, and the m/c vary a bit as well between the earlier and later models.

What you need to do, is check out the KZ650 model parts listings on this site. Just select the model you want to have a look at, and then look at the relevant parts page. You will see the differences in the calipers and master cylinders fitted to different year-model 650's, and this should help you identify which model 650 -you have.

Thanks G, I'll give it a go and let you know!

....Want to purchase some Progressive rear shocks for my Zephyr 750 - found some cheap new sets but none for the Zephyr 750 - However they are selling some shocks to suit a Zephyr 1100 - Will these fit my 750?

Also - the rubber manifolds between the motor and carbs need replacing - but I can't find any - will any other models fit?......

_____________

After weeks of browsing - some tips - best to learn from other people's (my) mistakes

The carburetor manifolds are available - but go under the name of carburetor holders in the USA - they are located in the cylinder head schematics - just to make things more difficult

temeculamotorsports.com - had a set

Hope the 1100 Progressive shocks fit my mounts (I ordered them) - They are also made to fit a Zephyr 400 - so not too concerned about spring rating

thanks Gosling1 - cheers all

no worries Mick - thanks for the tip about the US parts i.d

Good luck with the build, would be great to see some photos when its all done.

What are the spoke wheel rims made of from a mid 70's kwaka? Are they aluminium or something else?
The chrome is flaking off and I am thinking of getting them done black as opposed to rechroming them, not too sure yet tho.

[Gosling1]

they use steel rims. If the chrome is flaking off, take the wheels off, and the discs, tape up the bearing holes, and get the rims sandblasted to remove all the chrome - you could then powder-coat the rims black if you wanted. It would be a pretty good look I reckon, especially with new s/s spokes....

Hi, I've just joined as a new member, I have a 1980 Z750 H1 which was customised in the 80's, shortened frame, flat seat, less raked bars etc. I have kept the original custom style and am slowly each winter (i'm british so we have plenty of that !) improving it. I was wondering If anyone knew of better callipers that would fit or could be made to fit ? I was hoping to keep my discs as they are nearly new.

[Gosling1]

MG - you can fit the 2-piston calipers from the old GPX500 / ER5 or whatever that model was called in Pomgolia....

there are not a lot of calipers that can be fitted to these old 750's, as the clearance between the inside of the disc rotor and the mag wheel spokes is pretty tight - the OEM calipers are single-sliders as you know, and these are chamfered for clearance.....you can't fit opposed-piston 2-spotters or 4-spotters with the stock wheel and forks.

You could also consider using a m/c from a later model sports-bike - ZX6R or something, braided lines and HH pads - this will improve the standard brakes heaps.

Mate,
I'm a newbie with a tired 1984 zx750e1 which needs a new primary chain and I want to replace the oil pump while its down.
Finding this site has been pure gold! Just when I thought I was a bit demented about old Krackers I find there's a heap of nutters out there.
My question for Gosling1 is - will a primary chain and an oil pump from a 83 - 86 gpz750 fit into the zx? I suppose the question isn't so much will it fit but are the parts from these two models interchangeable.
Mate I don't expect any bloke to know the answer to all of these obscure questions, but any help you can provide would be greatly appreciated.
Cheers

gpz is a zx,they were brought out as zx but were named gpz or visa versa i may be wrong but someone will correct me if so

You should be able to use a primary chain and oil pump from either the 83 or 84 model GPz750, as this is actually a ZX750 in the first place (see below for explanation) - but you can only use these bits from the air-cooled 750's, not the water-cooled GPZ750R which was released in 1985 (one year after the 900R). If you can find an air-cooled 750 from 1984 or 85, then the primary chain and oil pump will be fine - its possible that you guys over there got some late-build air cooled 750's ? I guess you have the single-shock 750 with the swoopy bodywork ? The year range you have quoted (83-86) covers 2 different types of GPZ 750......

.....gpz is a zx,they were brought out as zx but were named gpz or visa versa i may be wrong but someone will correct me if so......

that's almost right - the generic name for a lot of the ZX models was GPz. Not all of them though, the 1982 GPz750 is actually known by the factory as an R1 - and it was a single-year model as well. From 1983 onwards, the GPz750 - the air-cooled model - was sold and known as a GPz750, but its actual factory designation was ZX750.

Things changed a lot in 1985 - when the GPz750R was released - it was actually a sleeved-down GPZ900R, and used almost all the 900 running gear. It was not a big seller here in Oz, no prizes for guessing why.....

Hope that helps, but unless the primary chain is making a *shitload* of noise in your ZX750, I would not bother changing it to be honest...they all make a bit of noise, but not much else.

You *cannot* fit an early Z900 / Z1000 motor into the z650/z750 frame. You can however fit the later GpZ1100 or Z1000J motors into the smaller frames. The reason is that the early 900s and thou's had the kickstart casting at the rear of the cases, the later 1000's and 1100's don't, and thus can be squeezed into a 650 or 750 frame.

I put a z1000 engine in a z650 way back in 82.

I have a very bad picture of it but the bottom line is that you are correct. You "cannot" do it... ( I had to assemble the engine INSIDE the frame wile it was UPSIDE DOWN ).

If I remember I can scan a few pictures of it...

[Yngve]

Here is my z650 with the z1000 engine.
Its a very old picture ( 1983 ) and I found it by chance on Facebook.
