What the number itself says

Reading 8QPSC.150SAA left to right: 8 is the model-year letter for 2008, QPS is the three-character code the EPA assigned to Qp-Sports as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and SAA is Qp-Sports' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Qp-Sports submitted for this family (model HY150T) carried engine code 157QMJ. In the Chinese engine-model convention that reads as one cylinder with a nominal 57 mm bore, QMJ series.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an engine control module (ECM). There is a catalytic converter in the exhaust, recorded as "oxidizing catalyst only". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 5.9 kW (about 8 hp) at 7,000 rpm, driving through an automatic.

Filing history and where it was sold

Qp-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, Zhejiang Summit Huawin Motorcycle Co., Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 4.6, HC 0.37, NOx 0.22 g/km.

Other records carrying the same engine code

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

• 8QPSC.050SAA (2008)

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.
