Differences Between 152FMH and Other CG Clones

Why not just use a Honda CG125 manual? Critical differences documented in the 152FMH manual:

1. Oil passage : The 152FMH has a smaller oil orifice to the cylinder head (to reduce top-end oil smoke). Using CG125 specs can starve the cam.
2. Starter motor compatibility : 152FMH often uses a smaller reduction gear (12 vs 13 teeth).
3. Bolt threads : Many 152FMH cases use JIS (Japanese Industrial Standard) threads – a standard metric bolt will cross-thread.
4. CDI pinout : The 152FMH AC-CDI has a different firing advance curve (max 28° vs Honda’s 32°).

The Oil Rotor Screen

Unlike cars that have a spin-on filter, the 152FMH uses a centrifugal oil filter rotor inside the right crankcase cover. The service manual dedicates an entire page to cleaning this rotor. If you don't clean the hardened sludge out of this rotor every 5,000 km, oil flow stops, and the camshaft welds itself to the head.
