apparently the rear shock is rated for someone who is 75 kgs and if you tighten the spring any more than the spring being 190mm then it doesn't work so good ....
i am 90 kgs and have my spring set at 190mm but i am buying a new spring for my weight in the winter ....

There are lots of threads on the shock, but you can only use 10mm of them before the spring is at it’s “minimum” length per the shop manual.

Factory setting is ~200mm long, minimum is 190mm long (unloaded).

I think some people have done that (maybe with HyperPro springs).
The problem is the valving in the shock is marginal even with the stock spring, probably going to be worse with a spring rate it wasn't designed for...

I'd personally (and this is my plan) just adjust the spring to the max (190mm) setting, live with it for a while, and save up for a Nitron R1 or K-tech.
The aftermarket shock will be much better, valved and sprung exactly for your weight (at least the Nitron - not sure how K-tech specifies spring rates).
I think even if you put a stiffer spring on now, you'd eventually want to upgrade further and you'd then be $100+ further behind.

I think for average solo street riding the spring is good for up to 195 lbs but you need to set the sag, as posted here no shorter than 190 mm.  For aggressive street or track 150 to 160 lbs ( look up Dave Moss suspension expert)
I weigh 200 with gear and  adjusting the sag on both ends made a big difference, I know a better quality shock would better yet but try the proper sag settngs first.
I don't think Kawasaki  planned on the average RS rider to be 150 lbs, if your talking north america that would be way low.
