turn

I've drained all the oil out and now want to refill it. But this won't come open :( I keep getting confused which way I should even be attempting to turn it which probably doesn't help haha

Hi, my blata rep.(C1) has been giving me some trouble, every time i turn, the bike starts to hop like crazy and is really out of balance. I don't know if it's the frame,tyres etc. does anybody have any suggestions to what might be causing it?
