What this record says

Sold in the US by: Pacific Rim International West, Inc.

Vehicle category: Highway Motorcycle - Ib (50-169cc)
Certificate numbers: 9HALC.150Z3L-001-R02

What the number itself says

Reading 9HALC.150Z3L left to right: 9 is the model-year letter for 2009, HAL is the three-character code the EPA assigned to Pacific Rim International West as certificate holder, C marks a highway (street-legal) certification, .150 is the displacement in litres, so 150cc and Z3L is Pacific Rim International West's 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 certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor, run by an ignition control module (CDI-type ignition). There is a catalytic converter in the exhaust, recorded as "TWC, single bed, open loop". The head carries a pulse secondary-air (PAIR) valve.

Rated power on the record is 6 kW (about 8 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Pacific Rim International West filed one certificate under this family, for model year 2009, sold as 49-state plus a separate California certification.

Certified emission levels: CO 6.1, HC 0.42, NOx 0.44 g/km.

What this configuration means when you shop for parts

Pacific Rim International West certified this engine with a carburettor, so the fuel-side wear items are the carburettor, its jets and float needle, the intake boot and the choke. The record gives no carburettor part number — measure the intake bore and the mounting on this engine before ordering.

The CVT behind this engine makes its drive belt, variator rollers and clutch shoes the consumables, so measure the old belt on the Zhenhua ZH-Z3L rather than ordering by displacement.

The PAIR valve Pacific Rim International West lists on this engine is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on Pacific Rim International West's 9HALC.150Z3L carries a catalyst, so a replacement silencer without one changes what this engine was certified with.

Models certified under 9HALC.150Z3L

Every model designation the importer listed on this certificate. If your machine's model name appears here, this is the right record — even if the name on the bodywork is slightly different.
