When it comes to 250CC buggy engines there is a confusing CN250-CH250-CF250 .Why all the hype?What about Yama buggy 250s which is some what different with the carb and air intake in the rear and is oil cooled?I'll post the Yama buggy again and you tell me. mancoman

id guess that the yama has a sym in it or yamaha 250

geek whats a sym?What about the other 3 classes CN-CH-CF? mancoman

No answers to what I asked except geek.Thanks geek. mancoman

sym is the carter engine

CH and CN 250 are basically the same engine.

The CFMoto has a similar setup in the top half of the motor, but adds two forward gears rather than one.

The CN250/CH250 on a buggy will only have forward, neutral and reverse. The CFMoto 250 has Hi, Low, neutral, and reverse gears.

Some parts between these are interchangeable, some are not.

Basically the same? What are the differences?

My Dazon 250 is rated a CH250.Is yours rated a CH250 or a CN250? mancoman

Does anyone know exactly what is interchangeable?

The Yamabuggy is a nice platform. Aircooled is simple but can lack power and durability.

The CH250 was in the honda Helix scooter and then was changed to the CN250 in 1986 for the new line up. Same motor, the letters designate new era/old era.
