Common SSR Bison 400 Problems and Their Solutions
1. Engine Won't Start or Hard to Start
Understanding the Issue:
A frequent concern among Bison 400 owners is difficulty in starting the engine. This could be caused by a range of factors, from fuel system issues to electrical faults.
Possible Causes:
- Fuel delivery problems
- Spark plug malfunction
- Dead battery
- Faulty ignition switch
- Carburetor issues
Troubleshooting Steps:
- Check the fuel system: Ensure the fuel tank contains fresh fuel, and there are no clogs in the fuel lines.
- Inspect spark plug: Remove and examine for signs of wear, carbon buildup, or damage. Replace if necessary.
- Test battery and connections: Ensure the battery is charged and terminals are tight.
- Inspect electrical components: Look into ignition switch and CDI unit functionality.
- Clean or rebuild the carburetor: Remove dirt or debris that may block fuel flow.
2. Loss of Power or Poor Acceleration
Understanding the Issue:
Reduced engine power impacts riding experience and may indicate underlying mechanical or fuel-related problems.
Common Causes:
- Clogged air filter
- Dirty carburetor jets
- Uneven compression
- Exhaust blockage
- Fuel line issues
Steps to Diagnose & Fix:
- Inspect and replace air filter: A dirty filter restricts airflow.
- Clean carburetor jets: Remove deposits that block fuel flow.
- Check compression: Use a compression tester to assess engine health; low readings suggest wear.
