What the number itself says

Reading JBVPX.264CYA left to right: J is the model-year letter for 2018, BVP is the three-character code the EPA assigned to Bv Powersports as certificate holder, X marks an off-road certification, .264 is the displacement in litres, so 264cc and CYA is Bv Powersports' 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 Bv Powersports submitted for this family (model TBM300) carried engine code JF173MH. In the Chinese engine-model convention that reads as one cylinder with a nominal 73 mm bore, MH series.

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 14 kW (about 19 hp) at 6,000 rpm, driving through a CVT (belt and variator).

Filing history and where it was sold

Bv Powersports filed one certificate under this family, for model year 2018, sold as 50-state, California included.

The vehicle itself is recorded as built by the same company, TAIZHOU TRAIL-BLAZER MANUFACTURING CO., LTD in China — engine and chassis from one source.

Certified emission levels: CO 6.0, HC+NOx 0.8 g/km.

Other records carrying the same engine code

Bv Powersports 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:

• GBVPX.264CYA (2016)
• HBVPX.264CYA (2017)

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.
