Hi! Try tilt your bike slowly to the right (sit on it and have a friend look in the glass). Then you will see the level "creeping" down open the window. This showing that your level is just in the upper level of the glass window. Which is correct. It also smells very warm. That is characteritic for the 535. Noticed the same behaviour. I think it´s normal & correct. But as someone said in a forum like this: How can this bike survive, if sold in the tropical countries...?.... Good question.
