The Symba has a simple robust clutch system that is shared with many Chinese motorcycles like Rusi, Lifan, etc.The service manual is a good guide with adequate pictures, but nothing is better than an actual video. I have come across Youtube videos showing not only how to disassemble but also how to replace the clutch linings when worn, as well as how to convert the clutch system to manual( yes, with a left hand cable actuated lever) Only one problem: none of them are in English.But, some are done so well you dont even need audio.if you are interested, let me know.I am actually putting together an English version .I am also trying to source parts from Asia, which are much cheaper.
