Known Issues
|
|
Clutch Wear:
|
Clutch plates can wear over time due to aggressive use, requiring replacement. Proper clutch fluid maintenance is key.
|
|
Carburetor Jetting:
|
Requires periodic adjustment based on altitude, temperature, and humidity for optimal performance. Incorrect jetting can lead to poor running or engine damage.
|
|
Suspension Seals:
|
Fork and shock seals can degrade over time, leading to oil leaks and reduced damping performance. Regular inspection and replacement are advised.
|
|
2-Stroke Engine Tuning:
|
Proper pre-mix ratio and spark plug maintenance are critical. Lean running conditions can cause engine seizure.
