Vehicle Information
Yamaha Big Bear 350 ATV (1987-1999)
The Yamaha Big Bear 350, produced from 1987 to 1999, was a robust utility ATV known for its capabilities. It featured a consistent 348cc (often rounded to 350cc) single-cylinder, 4-stroke, SOHC, air-cooled engine throughout its production.
Initially, the Big Bear 350 was exclusively offered as a 4x4 model. A notable change occurred in 1997 with the introduction of a 2x4 version, expanding drivetrain options. Concurrently, the shifter location was moved lower, closer to the engine, and later models incorporated a "super low first gear" instead of a separate low-range sub-transmission. Despite these transmission and drivetrain updates, the core engine design remained unchanged across the entire 1987-1999 range. FAQ:
Q: How can I ensure parts compatibility for my Big Bear 350?
R: Parts compatibility can vary by year and trim (2x4 or 4x4) of your ATV. Please use our year and model selector to find the exact parts for your vehicle.
Maintenance
| Component | Interval | Details |
| Oil Filter | With every oil change | Some sources suggest changing oil and filter annually or every 10 000 km. |
| Spark Plug | Inspect and replace as needed | Consult the owner's manual for the precise interval. Weak spark can lead to incomplete combustion. |
| Air Filter | Every 12 months or every 100 hours | Replace more frequently if used in dusty or muddy conditions. Regular cleaning is essential. |
| Coolant | Check level regularly. Change at least annually or every 8 000 km. | Use an ethylene glycol antifreeze with corrosion inhibitors for aluminum engines, mixed 1:1 with distilled water. |
| Belt | Not applicable | The Yamaha Big Bear 350 typically uses a shaft drive system, not a belt for the main transmission. |
