I recently bought both a chinese motorcycle and a generator off of different ebay sellers.  After only 800 hours use the generator is now scrap ,it was a copy of a yanma diesel 5.75 kva and cost around 650 pounds a waste of money yes, but more importantly on both the the motorcycle an apache 125 made by bashan and the generator made by suntom the rubber fuel pipe used was sub standard and appears to perish very quickly causing fuel leaks. so if you own of have just bought any chinese equipment please make sure the fuel lines are not perishing and really to be safe i would suggest changing them for better quality lines .
