Clutch Fluid:

DOT 4 (FMVSS No. 116 DOT 4) - Hydraulic clutch

Common Issues:

Some early models may experience occasional FI warning light illumination (often related to sensor issues). Stator output can degrade over time. Cam chain tensioner can sometimes become noisy if not properly maintained. Rear shock absorber can lose damping effectiveness over extended use and mileage. Chain and sprockets wear is typical for chain-driven bikes.

Maintenance Tips:

Regular chain lubrication and adjustment are critical. Proper coolant level and quality ensure engine longevity. Checking valve clearances at recommended intervals prevents potential engine damage. Keeping battery voltage healthy is important for the EFI system.
