Vehicle Information
Yamaha SR433 Snowmobile (1973-1978)
The Yamaha SR433 is a high-performance racing snowmobile, primarily produced in the early 1970s. For the North American market, the SR433 model was available until 1973. It was renowned for its handling and speed. These snowmobiles were equipped with a 433 cc, air-cooled, two-stroke parallel twin engine, featuring 5-port induction and chrome-plated aluminum cylinders. While the SR433 designation might appear to cover a broader period in some discussions, specific models like the SR433, SR433B, and SR433C represent distinct year-specific iterations, each bringing incremental performance improvements. For instance, horsepower increased from approximately 45 hp in 1971 to 70 hp for the 1973 model. After 1973, production of SR models for the North American market ceased. FAQ:

Maintenance
| Component | Interval | Details |
| Engine Oil | Check and refill as needed | SR433 models use an Autolube oil injection system. Oil is automatically mixed with fuel. The oil tank should be kept filled (capacity of approximately 2.25 liters). |
| Oil Filter | Not applicable | Due to the Autolube system on these two-stroke engines, there is no conventional engine oil filter to change. |
| Drive Belt | Inspect pre-season and in-season. Replace approximately every 3 200 km or sooner if wear is observed. | |
| Spark Plug | Inspect and replace approximately every 3 200 km or if wear is observed. | Recommended gap is 0.7-0.8 mm. |
| Air Filter | Check and clean regularly |
