Hi, I'm a new member from Bulgaria and I'm a owner of Simson suhl SR2. It was to my grandfather but he give it to me to use it. I like the moped very much but I have some problems with it. If someone can help me I'll be very thankful. So the problem is that now I disjoint all parts, because I want to repaint it and i hear a strange noise from the clutch and the moped is loosing power - it is difficult to climb a little hight on 1 gear and strange metallic noise is hearing from the engine - like a noise from a spring. The other question is what kind of oil for transmission and the section of the clutch to use - is it the same or not?
