Vehicle Information
Suzuki Quadsport Z400 ATV (2003-2014)
The Suzuki QuadSport Z400 (LT-Z400) was a popular sport ATV produced from 2003 to 2014. It featured a consistent 398cc, 4-stroke, single-cylinder, liquid-cooled, DOHC engine throughout its run, known for its performance and reliability. A significant update occurred in 2009, transitioning from carburetion to electronic fuel injection (EFI) for improved throttle response and starting. This update also included a revised intake, updated cam profiles, a wider front track, wider foot pegs, and a stiffer frame. Further chassis refinements, including a wider stance, were introduced in 2012 to enhance handling. While primarily a single base model, "Special Edition" or "Limited Edition" trims were offered in certain years (e.g., 2008, 2011-2012) with unique graphics or minor component upgrades. FAQ:

Maintenance
| Component | Interval | Details |
| Engine Oil | Replace initially at 1 month, then every 6 months | Change when engine is warm. |
| Oil Filter | Replace initially at 1 month, then every 6 months | Replace at the same intervals as engine oil. |
| Spark Plug | Inspect every 6 months. Replace every 18 months. | |
| Air Filter | Clean every 3 months. Replace if worn, damaged, or dirty after cleaning. Some sources suggest replacement after 100 hours or annually. | More frequent cleaning in dusty conditions. Operating with a torn or absent filter accelerates engine wear. |
| Coolant | Replace every 2 years | Use SUZUKI COOLANT or equivalent for aluminum radiators, mixed 50:50 to 40:60 with distilled water. |
| Drive Chain | Inspect before every ride. Clean and lubricate regularly. Adjust slack to 30-40 mm. Replace if 20-pitch length exceeds 319.4 mm. | Clean with kerosene, lubricate with heavyweight motor oil. Avoid solvents that damage O-rings. Do not use commercially sold 'drive chain oil' that can damage O-rings. |
