Vehicle Information
Yamaha RT3 360 Motorcycle - Dual-Sport (1973)
The 1973 Yamaha RT3 360 was a robust dual-sport motorcycle, part of Yamaha's evolving RT series. Known for its powerful air-cooled, two-stroke, single-cylinder engine, it offered a displacement of 351 cc or 352 cc, producing 28 to 33 HP, paired with a 5-speed transmission and Yamaha's AutoLube oil injection system. For 1973, the RT3 360 was offered as a single model, often called the "RT3 Enduro 360," exclusively in "Baja Brown." While the RT series saw generational changes from the RT1 (1970-1971) and RT2 (1972), the 1973 RT3 itself did not undergo mid-cycle engine or generation changes. A notable improvement for the RT3 from previous models was the adoption of a 21-inch front wheel to enhance handling. Q: Is this product compatible with my 1973 Yamaha RT3 360?

Maintenance
| Component | Interval | Details |
| Engine Oil Filter | Not applicable (no traditional filter) | The engine uses Yamaha's AutoLube oil injection system and does not have a traditional engine oil filter. The AutoLube pump requires periodic adjustment by a Yamaha dealer. The transmission oil change interval is not explicitly detailed in the official manual. |
| Drive Belt | Not applicable (uses a chain) | The Yamaha RT3 360 uses a drive chain, not a belt. The chain must be cleaned and lubricated regularly as per the intervals specified in the owner's manual. More frequent maintenance is required in dusty or wet conditions. Drive chain slack should be checked before each ride. |
| Spark Plug | Replace if not functioning correctly, electrodes worn, or excessive deposits | The standard spark plug is an NGK B-9ES. The gap should be set between 0.6 and 0.7 mm. The manual advises replacing the spark plug if it is not functioning correctly, if electrodes are worn, or if deposits build up. General guidelines suggest replacement every 13,000 to 16,000 km or as needed. |
| Air Filter | Clean at least once a month | The motorcycle is equipped with a reusable, oil-impregnated foam air filter. Clean more frequently (potentially weekly) if the motorcycle is ridden in dirty or dusty conditions. |
| Coolant | Not applicable (air-cooled engine) | The 1973 Yamaha RT3 360 engine is air-cooled and does not use liquid coolant. |
