Filing history and where it was sold

Gk Motor Sports filed one certificate under this family, for model year 2008, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, Shanghai Goka Sports Motor Co., Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 1.7, HC 0.12, NOx 0.37 g/km.

Other records carrying the same engine code

Gk Motor Sports certified an engine with this code under 2 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• 7GKMX1.31GML (2007)
• AGKMX1.31GML (2010)

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
