these are simple forks. you can use any viscosity. but higher viscosity will firm the forks up a little. I fitted YSS front springs with springs preload adjustment. they sent me 15W oil. i am not sure what an actual viscosity it is as there is no information anywhere. Kawaski uses SS8, which has around 36 viscosity (at 40C). it is similar to Motul 10W.

it is firmer. and you have spring preload. is it worthy the upgrade? i am not sure; it depends on your preferences. I also fitted the rear YSS shock which is very nice, as it has damping adjustment.

Since back racing enduros where we used ATF in our forks, I've ALWAYS used ATF in any bike I had (BOTH my '08 in AZ and '15 in BC have ATF in their forks).
