Vehicle Information
Yamaha RD350 Motorcycle - Street (1973-1975)
The Yamaha RD350, produced from 1973 to 1975, is an iconic motorcycle renowned for its sporty performance, powered by an air-cooled, 347 cc two-stroke parallel twin engine. It featured innovations such as reed-valve induction (Torque Induction) and the automatic Autolube oil injection system, eliminating the need for manual fuel-oil mixing. This model represented a significant evolution from its predecessor, the Yamaha R5, offering a dynamic and responsive riding experience. Throughout its production from 1973 to 1975, the RD350 maintained very consistent core engine specifications and platform. Changes between model years were minimal, primarily limited to designations (RD350 in 1973, then RD350B for 1974-1975) and cosmetic updates such as new paint schemes. The 1974 model was virtually identical to the 1973 model, apart from price adjustments. Q: Are parts for the 1973 RD350 compatible with 1975 models?
R: While 1973 to 1975 models share many similarities, minor differences may exist. Please use our year and edition selector to ensure exact part compatibility.
Maintenance
| Component | Interval | Details |
| Autolube Oil Level (Engine) | Before each ride | Check and top off as needed. The Autolube system is a separate oil injection system for the two-stroke engine, without a traditional spin-on oil filter. |
| Transmission Oil | As per owner's manual | Check and top off or replace as per manual recommendations. No specific filter interval was found. |
| Drive Chain | Lubricate every 250-300 km | Lubricate more frequently (every 100-150 km) under severe usage. Regularly check chain and sprockets for wear and proper tension. |
| Spark Plugs | Every 13,000-16,000 km or annually | Check, clean, or replace as needed. Electrode gap should be 0.5 mm to 0.6 mm. |
| Air Filter | Every 16,000 km or as needed | Clean by blowing compressed air from the inside out. Replace if clogged. Clean more frequently in dusty conditions. |
