I looked for that buggy but didn't see it. I'm not worried about the buggy because BMS gives you a one year warranty! I just want a service manual. I looked up the engine and it is a HH465Q-2E made by Beijing Yichy Tec Co. LTD. Appearently, this motor is used in many foriegn cars. I just don't know which one and have'nt brushed up on my Chinese. I am sure however that it is a copy of some other engine, just like the Japanese did in the early 60s and 70s. The Chinese are into copying, not R &D. So, I'm just trying to find the originator of the motor and the manual to go with it!
