A few questions about the Kawa GPZ 500s!

Hi guys. Have my Kawa GPZ 500s built for almost 2 weeks now.90. Now I would have a few questions. Where exactly do I read the oil level? I unscrewed the lid, but there’s no stick on it to read off. Below is a glass, but I don’t know how high the oil has to stand there. Another question. Where can I refill the cooling water? I haven’t found anything yet. And now my last question. How high can I turn it if I want to warm it up? I always have up to max 5000turns. If I drive 100km/h, then it is almost at 5000 turns. Hope someone can answer my questions or give me any other tips. Thank you
