Whenever I am at Full Throttle My Engine Bogs Out

The problem of an engine bogging out is commonly caused by inefficiency of fuel or air flow or ignition to the carburetor. With a newer scooter, this could be caused of a few situations and one of them could be caused by driver error. When you're under full throttle, the governor will not allow you to get any more power - and will result in a situation where the engine appears to bog down. However, if the issue is not with the governor, it may be directly related to other mechanical issues that can be diagnosed and fixed. Here are a few items to check along with a solution to fix them in many cases.


  1. Check the Air Filter: The most common reason why an engine bogs out under acceleration is because the air/fuel mixture is 'dirty' or inefficient. If the air filter is clogged or has a lot of dirt in it, it could be bogging down the engine. Clean the air filter and see if the problem goes away.

  2. Check the Carb: If your scooter is new, you might need to adjust the needle on the carburetor slide. To do this, find the carburetor through the panel under the seat. Take the screws out of the top of the carburetor, which will expose the carb. Pull the slide out with the needle attached. There are 3 notches on the needle. If the scooter is stock, this will be in the middle. Move the needle up to the top slot and put it back together. If your scooter is used, then still check the needle, but take the carb out, unscrew the bottom of the carb, and clean the bowl.

  3. Clean the Carb: Sometimes dirt or filth can get in the carb and clog the main jet or pilot and will not allow fuel to flow properly. If this happens, you'll need to clean the carburetor to remove any 'gunk' or obstructions that are causing the bogging situation. Sometimes using carb cleaner to spray into the carb throttle body is easy enough, while other times complete disassembly and cleaning is the best solution.
