The 1981 Suzuki RM250 is a two-stroke dirt bike designed primarily for motocross racing. Known for its lightweight frame and agile handling, it has a solid reputation for performance among enthusiasts. However, like any older model, it has its share of common issues that owners should be aware of.
Common Mechanical Problems & Known Weak Points
Engine & Power Delivery
One common issue is a lack of power or bogging during acceleration. Symptoms include sluggish performance and difficulty maintaining speed. This can occur due to a clogged exhaust or worn piston rings. A practical fix involves cleaning the exhaust and checking the piston for wear, replacing it if necessary.
Fueling or Intake Issues
Owners may experience inconsistent idling or stalling. This is often caused by a dirty carburetor or fuel lines. Regular cleaning of the carburetor and ensuring fuel lines are free from obstructions can prevent these issues.
Suspension Problems
Front fork leaks are a common concern, leading to poor handling. Symptoms include a soft front end and oil on the fork tubes. Replacing seals and ensuring proper fork oil levels can resolve this issue.
Electrical or Starting Issues
Starting problems may arise from a weak battery or faulty ignition system. Symptoms include difficulty starting or no response when the kickstarter is engaged. Regularly checking the battery and ignition components can help maintain reliable starting.
Transmission or Clutch Concerns
Clutch slippage is another issue, often indicated by a loss of power during acceleration. This can be caused by worn clutch plates. Replacing the clutch plates and adjusting the cable tension can restore proper function.
Brakes or Handling
Brake fade or sponginess can occur, leading to reduced stopping power. This is typically due to worn brake pads or air in the brake lines. Regularly inspecting and replacing brake pads, along with bleeding the brake lines, can enhance safety.
