3 of the 6 US certificate filings on record for Caltestco, Inc name an engine manufacturer in China, across 2006–2007: Jiangsu Dhclbc Vehcile Manufacture Co., Ltd., Luoyang Northern Ek Chor Motorcycle Co., Ltd.. The rest of the range is built elsewhere and is not covered by this registry.

Will parts from another brand fit my Caltestco, Inc?

A shared factory and engine size makes another brand a strong candidate, but it does not prove the part numbers match. These machines are assembled from multiple component suppliers, so measure the part you have before ordering a replacement.

What the Caltestco filings say about the engines

Every Caltestco filing on record is carburetted — 3 certificate rows, 2006 to 2007, and not one fuel-injected engine among them.

2 of the 3 filings are 50-state (California-legal); the other 1 were 49-state only.

Rated power across the range runs from 2.2 kW to 5.8 kW (about 3 to 8 hp).

The vehicle builders named are Jiangsu DHCLBC Vehicle Manufacture Co., Ltd. and Luoyang Northern Ek Chor Motorcycle 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.
