I understand your predicament although bummer there are no tracks in Israel, would you not be able to visit the UAE with the bike and ride tracks there?
As for Racers and suspension settings, most will have ditched the stock suspension and will have no other advise for you other than the rear end of the bike is poor and to throw money into it with a replacement. You would be better looking at track day people who have had to deal with the same issues here even if they went to a track suspension specialist to help them dial it in. Of course, smaller countries including Finland do not have a wealth of specialists on standby at tracks to help out so like you we have to come here and research the info here and do trial and error.
My understanding of the Gen 4 ZX10R is that conventional sag settings are not effective. Now I used Sportbike Riders settings as a test baseline to start with and made a little adjustment for myself. Also, I am running a larger rear tyre (now a Bridgestone RS10 200/55) which will raise the rear end a little as well.
Do some searches on Sag for the Gen 4 and also shimming the rear shock which is a cost effective way to raise the rear end and get the standard suspension working a bit better. Some people also prefer adding links to the chain and running the rear wheel further out on the swingarm to give better stability but then there are others that prefer the stock chain length and the quicker change of direction. With the front end the consensus is the forks are good enough and to run them near flush in the tripple clamps.
unfortunately dialing in these bikes takes some trial and error based on what you want from them. No model is the same either and even the same model can be different depending on mods done and how it delivers power through the rev range etc.
Here is a good starting point

Look under the zx10r and then see how you go, tweak based on how you feel the bike performs. Maybe run a little softer given your weight or if you download the Service Manual from here, check what it recommends for oil and the stock settings for suspension from Kawasaki and use them as a baseline.
This is also a good read on the Gen 4 for you with regards to suspension
Anyone have some suspension geometry advice
