Answer 1

If your Honda CBR 250R is experiencing a loss of power when the RPM hits 5000 and the speed exceeds 90 km/h, it's important to investigate potential causes. Here are a few possibilities:

1. Fuel System Issues: Check the fuel system components, such as the fuel filter and fuel pump, for any clogs or malfunctions. A restricted fuel flow can lead to insufficient fuel reaching the engine, resulting in a loss of power.

2. Air Intake Problems: Inspect the air filter for any blockages or excessive dirt accumulation. A clogged air filter can restrict the airflow to the engine, affecting performance at higher RPMs. Ensure that the air filter is clean and properly installed.

3. Exhaust System: Examine the exhaust system for any restrictions or leaks that could affect the bike's performance. A blocked or damaged exhaust can impact power output and cause performance issues.

4. Spark Plug Condition: Check the spark plugs to ensure they are in good condition and properly gapped. Worn or fouled spark plugs can lead to misfires and a loss of power. Consider replacing the spark plugs if necessary.

5. Ignition System: Inspect the ignition system components, such as the ignition coil and wires, for any faults. A weak or failing ignition system can result in inadequate spark and reduced power output.

6. Mechanical Issues: If all other possibilities have been eliminated, there may be underlying mechanical issues within the engine or transmission. These can include problems with the valves, piston rings, or clutch. It might be necessary to perform a more detailed inspection or even a compression test to identify any internal problems.

Since the showroom was unable to identify the issue, it may be beneficial to seek a second opinion from another reputable motorcycle mechanic or authorized service center. They may have additional expertise or diagnostic tools to pinpoint the exact cause of the power loss. Providing them with detailed information about the symptoms and any recent maintenance or changes made to the bike can assist in the troubleshooting process.
