Hello, I recently purchased a yingang enduro 250cc bike and it was running great. Unfortunately the header pipe that connects the carberautor to the muffler broke off. I cannot find where to get parts and the supplier is not helping at all. Does anyone know where I could get this part and other Yingang parts? Also do they use Honda motors and can I just use a Honda dirt bike header pipe to fix it. Thanks and any help is greatly appreciated, I want to ride!!!
