Tightening torque sprocket and sprocket Z400 year 2020

Hey, I’d like to change my chain as well as the sprocket and sprocket on my Z400 year 2020. Could someone tell me what the respective tightening moments are for the screws on the sprocket as well as for the sprocket? Thank you already in advance! PS: Where can I find the workshop repair manual for the new Z400s from the current millennium?! I don’t find anything for my model on the Internet. Is Kawasaki generally rather reluctant when it comes to such information? other manufacturers are clearly more transparent. At least this is my impression.
