Known Issues

Electrical Gremlins:

Age-related degradation of wiring harness insulation and connectors can lead to intermittent electrical issues. Corrosion is also a common factor.

Carburetor Vs Injection:

While this is an IE model, earlier versions used carburetors. Fuel injection systems (like Weber-Marelli) can be sensitive to fuel quality and require specific diagnostic tools for advanced issues.

Desmodromic Maintenance:

Desmodromic valve systems, while effective, require precise adjustment and maintenance, especially valve clearance checks, to maintain performance and prevent wear.

Fuel Tank Corrosion:

Older fuel tanks, especially those made of steel, can be prone to rust if not properly maintained or if fuel sits for extended periods.
