What this record says

Sold in the US by: Puma Cycles Corporation
Engine built by: Benneng
Vehicle category: Highway Motorcycle - Ia (<50cc)
Certificate numbers: DPUMC.049ZEN-002

What the number itself says

Reading DPUMC.049ZEN left to right: D is the model-year letter for 2013, PUM is the three-character code the EPA assigned to Puma Cycles as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and ZEN is Puma Cycles' 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. 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 2.1 kW (about 3 hp) at 7,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Puma Cycles filed one certificate under this family, for model year 2013, sold as 49-state (not certified for sale in California).

The vehicle itself is recorded as built by Foshan Fosti Motorcycle Co Ltd in China, while the engine came from Benneng. Chassis parts and engine parts therefore have different origins.

Certified emission levels: CO 1.0, HC 0.20, NOx 0.58 g/km.

What this configuration means when you shop for parts

Puma Cycles certified this 49cc engine with a carburettor at 49cc, 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 49cc engine before ordering.

The CVT behind this 49cc engine makes its drive belt, variator rollers and clutch shoes the consumables; belt length and width vary between 49cc machines, so measure the old belt on the ZN50QT-8C rather than ordering by displacement.

The PAIR valve Puma Cycles lists on this 49cc engine is an emissions part; its hoses perish and are the usual cause of popping on the overrun.

The exhaust on Puma Cycles' DPUMC.049ZEN carries a catalyst, so a replacement silencer without one changes what this 49cc engine was certified with.

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.
