sprocket camshaft Kawasaki kz 1000 Andrews

Hello.Does anyone have information for which shafts such sprockets were produced?Thanks.     

Those are HYVO adaptor sprockets to enable the earlier KZ900/1000 3 bolt cams to be used in the later Z1000J/GPZ1100 engines.
This is because 3 bolt fitment performance cams for the earlier KZ engines are more common than 2 bolt fitment ones for the later J type engines.
The same sprockets are still available from APE..
 

Thanks for the info.But what is the point in installing shafts from 900?The rise and phase at 1000j seems bigger to me. Or is it not?

You are correct when referring to factory camshafts.  But those sprockets are for running aftermarket high lift and/or long duration cams meant for earlier models as their availability is more accessible as Zed1015 mentioned.

Andrews Camshafts are a aftermarket cam and gear producer that are still in operation today. They were founded in 1972 so they did manufacture cams for the Z1 very soon after they first rolled off showroom floors.

Unfortunately they no longer make cams for Import engines, only Harley Davidson.

As mentioned by others those sprockets fit earlier Z1 type 3 bolt cams on later engines. All stock Hyvo chain sprockets have only 2 bolt mounting holes (650/750 1000/1100/1300)

As stated in my first reply.
The availability of off the shelf kz900/1000 three bolt fitment performance cams are vastly more abundant than those with J/GPZ type 2 bolt fitment.
Those sprockets enable the retro fitting of the earlier and more common, three bolt roller chain driven performance cams into the later Hyvo chain equipped engines.
As for the KZ903, KZ1015 - 1000J,Z1100,GPZ1100B cam profiles.
There is very little notable difference between lift of any of those stock cams with only the 83-85 GPZ1100 Unitrack cams having reasonable increases in lift and duration which makes them a worthwhile and well documented stock upgrade for the "cooking motors" and they are also popular for use as a turbo cam in road going applications once degreed in to the correct settings. 

Hello. Thanks.But there is a question, there are no slots on these sprockets to adjust the shafts. How then to expose them?

To properly set the phases and compensate for the stretching of the chain for the kz-1000, gpz-1100 shafts, I changed the original standard sprockets and all this worked fine.

Good call.
Yes! ideally they should be slotted for accurate adjustment like the APE ones are..
It's likely they were simply to allow a direct bolt in conversion to run around 110 degrees with no fine adjustment .
Most cams will bolt in on the stock non adjustable sprockets and be close enough for road use and your average punter who hasn't the tools or the skill to degree them in perfectly ..

Thank you 👍🏼 Interesting...... So I'll have to try to dress these sprockets on camshaft 3x, which I have and see what happens in time. But this is when the head arrives with the replacement of the guide bushings.....Although, of course, setting the camshaft by overlap in mm is tdc, much faster and easier than by degrees.
Do you have no information what is the overlap of mm valves in tdc for standard Kawasaki camshaft?I have never been able to calculate this exactly.......
 

By the way, these are the same rc engineering without a groove under the puck. About which they have already mentioned more than once on the forum.

Very nice score  .
Vastly reduces the chance of a shim escaping..
As for cam timing. I've always used the lobe centre method.
