Who actually makes Apt Powersport and Utility Products, LLC?

What the Apt Powersport and Utility Products filings say about the engines

Every Apt Powersport and Utility Products filing on record is carburetted — 11 certificate rows, 2011 to 2018, and not one fuel-injected engine among them.

The engine codes on Apt Powersport and Utility Products' test vehicles —2 distinct across the filings — are led by 1P39FMB and 1P52FMI. The code is stamped on the crankcase and is a better search term than the badge.

6 of the 11 filings are 50-state (California-legal); the other 5 were 49-state only.

Rated power across the range runs from 1.8 kW to 5.6 kW (about 2 to 8 hp).

The vehicle builders named are APT Powersport and Utility Products, LLC, Zhejiang Xingyue Vehicle Co., Ltd., Wuhu Fourstar Machinery Co., Ltd. and Yongkang Fourstar 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.
