What the Guangzhou Haojin (America) filings say about the engines
Every Guangzhou Haojin (America) filing on record is carburetted — 6 certificate rows, 2008 to 2010, and not one fuel-injected engine among them.
The engine codes on Guangzhou Haojin (America)'s test vehicles —2 distinct across the filings — are led by HJ162FMJ and HJ167FMM. The code is stamped on the crankcase and is a better search term than the badge.
4 of the 6 filings are 50-state (California-legal); the other 2 were 49-state only.
Rated power across the range runs from 2.2 kW to 11 kW (about 3 to 15 hp).
The vehicle builders named are Zengcheng Haili Motorcycle Co., Ltd and GUANGZHOU HAOJIN MOTORCYCLE INCORPORATED CO.，LTD — the chassis and the engine do not always share a source.
Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
