Carburetor Tuning:
Carburetor tuning might be necessary for optimal performance, especially after modifications or at different altitudes. The manual will provide base settings.
Wide Tire Considerations:
The unique wide rear tire, while excellent for traction, can increase rolling resistance and affect handling dynamics on paved surfaces compared to narrower tires. Proper tire pressure is crucial.
Suspension Wear:
Like any motorcycle, fork seals and rear shock absorbers can wear over time, requiring replacement or seal maintenance. The manual details these procedures.
Electrical Connections:
Corrosion in electrical connectors can be an issue on older bikes, particularly if exposed to moisture. The manual's wiring diagrams are invaluable for troubleshooting.
