Question

While accelerating the Bajaj dominar (bought 2nd hand) have the problem like the power is a little bit buzzy, like struggling to attain power but after 4-5k rpm it have much power on offer and under these rpms its like pulling back the bike.why?

Answer 1

The issue you're describing with your Bajaj Dominar, where it feels buzzy and struggles to attain power at lower RPMs but improves after reaching 4-5k RPM, could be attributed to several factors. Here are a few possibilities:

1. Engine Tuning: The engine tuning or fuel-air mixture could be affecting the performance. It's possible that the bike is running too lean (less fuel) at lower RPMs, leading to a lack of power. At higher RPMs, the mixture could be adjusted, providing better power delivery.

2. Carburetor/Throttle Body Issues: If your Dominar is equipped with a carburetor or throttle body, it's possible that there could be an issue with its calibration or cleanliness. A dirty or improperly calibrated carburetor/throttle body can affect the fuel-air mixture and cause uneven power delivery.

3. Ignition System: Problems with the ignition system, such as faulty spark plugs or ignition coils, can impact the bike's power delivery. Inadequate spark at lower RPMs can result in a lack of power or misfires, causing the symptoms you described.

4. Air Intake/Exhaust Restrictions: A restricted air intake or exhaust system can impact engine performance. If the air filter is dirty or the exhaust system is clogged, it can hinder the engine's ability to breathe properly and affect power output.

5. Mechanical Issues: It's also worth considering if there are any mechanical issues with the engine or drivetrain components that could cause the power delivery problem. This could include issues with the valves, piston rings, or clutch system.

To address this issue, I recommend taking your Bajaj Dominar to a trusted mechanic or Bajaj service center. They will be able to diagnose the problem more accurately by conducting a thorough inspection and, if necessary, performing tests or adjustments to the engine, fuel system, or ignition system. They may also check for any mechanical issues that could be causing the symptoms you're experiencing.

Remember, diagnosing and resolving specific mechanical issues is best done by a professional who can physically inspect the bike and perform the necessary tests.
