Which Kaitong models have a Chinese-built engine?

What the Kaitong filings say about the engines

Every Kaitong filing on record is carburetted — 2 certificate rows, 2017, and not one fuel-injected engine among them.

The engine codes on Kaitong's test vehicles —just one across the filings — are led by 157QMJ. The code is stamped on the crankcase and is a better search term than the badge.

None of the 2 filings is a 50-state certification: these were sold as 49-state machines, not certified for California.

Rated power on the record is 5.8 kW (about 8 hp).

The vehicle builder named on every row is Taizhou City Kaitong Motorcycle Manufacture Co., Ltd.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
