What to Do When the Motorcycle Makes a Buzzing Sound When Accelerating but Doesn't Speed Up?

First, unscrew the bolts that secure the motorcycle's carburetor. Turn off the motorcycle's fuel tank switch to prevent fuel from entering the carburetor. Once the bolts securing the motorcycle's carburetor are removed, the carburetor can be taken out. Spray cleaner inside the motorcycle's carburetor to clean it, then reinstall it to complete the operation.

As a seasoned rider with over a decade of motorcycle experience, when encountering a situation where the throttle roars but the bike doesn't move, I recommend starting your inspection with the drivetrain. A loose chain can cause slipping, and a broken belt will completely fail to transmit power—no matter how loud the throttle sounds. Worn clutch plates are a common issue; if you rev hard in third gear and the RPMs soar without a corresponding increase in speed, it's likely time to replace the clutch. Also, check tire pressure—if it's below 1.8 kg, the wheels will struggle to turn. Finally, don’t forget to inspect the exhaust pipe; if it's clogged with mud, the engine will be choked and lose power. It’s best not to tough out these minor issues yourself—promptly consulting a mechanic is the safest approach.
