Vehicle Information
Kawasaki KH400 Motorcycle - Street (1975-1978)
The Kawasaki KH400, produced from 1975 to 1978, is a classic two-stroke, air-cooled, three-cylinder motorcycle. While the KH400 designation began in 1976, the 1975 model was known as the S3 400, sharing the same 400cc engine displacement. This era of motorcycles is renowned for its distinctive performance and sound. A significant model generation shift occurred in 1976. The KH400 (A3) replaced the S3 400, largely due to evolving environmental regulations. This transition brought several key changes: the engine's horsepower was reduced from 42 hp (S3) to 38 hp (KH400) due to a reworked exhaust and airbox. The ignition system was updated to a CDI (Capacitor Discharge Ignition), replacing the older points system. Other enhancements included water-resistant brake pads and an uprated single disc front brake. The 1977 (A4) and 1978 (A5) models primarily featured cosmetic updates, such as new paint schemes, maintaining similar specifications to the 1976 KH400. FAQ:

Maintenance
| Component | Interval | Details |
| Two-stroke oil (injector system) | Check and top up as needed | The KH400 uses a two-stroke engine requiring a specific oil and fuel mixture. The oil level in the separate tank for the injector system should be checked regularly. |
| Transmission oil | Check level regularly | The transmission requires 1.1 liters of SAE 10W30 or 10W40 motor oil (SD or SE rated). The level is checked via a dipstick. |
| Drive chain | Clean and lubricate every 500 to 800 km; check tension | The KH400 uses a conventional roller chain. The entire drivetrain (chain and sprockets) should be inspected once per season, especially after several thousand kilometers. |
| Spark plugs | Inspect, clean, and re-gap periodically | Check for fouling or wear and replace if necessary. |
| Air filter | Clean or replace every season | The KH400's airbox was designed to be more restrictive in later models (e.g., KH400 A3 in 1976) for sound level control. |
| Coolant | Not applicable | The Kawasaki KH400 features an air-cooled system and therefore does not use liquid coolant. |
