What the Kayo Motor Machinery filings say about the engines

Every Kayo Motor Machinery filing on record is carburetted — 1 certificate row, 2007, and not one fuel-injected engine among them.

The engine codes on Kayo Motor Machinery's test vehicles —just one across the filings — are led by 1P55FMJ-2E10. The code is stamped on the crankcase and is a better search term than the badge.

All 1 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power on the record is 9.2 kW (about 12 hp).

The vehicle builder named on every row is Jinyun Kayo Motor Machinery 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.
