Why does my bike keep bogging?
Causes of Bogging and Possible Solutions The most common reason is that your air/fuel mixture is inefficient or dirty. If your air filter is clogged or has a lot of dirt. It could be bogging down the engine. Consider cleaning the air filter or replacing it with an air kit to see if the problem is resolved.
Why does my bike die when it idles?
The most common reasons are carburetor issues such as a vacuum leak, fuel leak, or tuning issues. Other culprits could include corroded or cracked spark plugs or spark plug wires, a faulty ignition coil, a clogged air filter, or engine timing issues.
What does it mean when your bike won’t idle?
1. Engine starts with medium choke and slight throttle 2. Must hold slight throttle and feather choke to keep engine running 3. Engine will rev with throttle, but is rough at times (because it is choked) 4. If I release throttle then the engine dies immediately 5. If I turn choke completely off then the engine gets weaker and weaker until it dies
What’s the idle speed on a Yamaha bike?
The bike hasn’t been running to my knowledge for 4-5 months. Prior to my purchase the previous owner, a friend, said he cleaned the carbs. Basically, she’ll start up fine and idle around 1500-2000 rpm (full choke) but upon going to 1/2 choke or giving her any throttle, she dies.
How to troubleshoot a rough idle in a motorcycle?
Check the carburetor idle circuit for blockage. Check the fuel injectors for damage or blockage if applicable. Ensure the carburetors are synchronized if the motorcycle uses multiple carburetors. Make certain the battery is fully charged and all battery cables are tight and free of corrosion and sulfate deposits.
What to do if your bike won’t run without a choke?
Normally you would keep it on (closed) until the engine warms up and then turn it off (open). If it really won’t run without the choke being closed/on then it’s not getting enough fuel and the carbs probably need cleaning.

Why does my dirt bike not turn on?
As there engine temps rise, less fuel is required to keep it running. This is why some dirt bikes need to have the choke on left longer to keep them running without needing to give it more gas by twisting the throttle. 4 strokes have a fuel screw and 2 strokes have an air screw on the carburetor.
What do the 4 strokes on a dirt bike do?
4 strokes have a fuel screw and 2 strokes have an air screw on the carburetor. They both perform the same type of function, but in opposite ways. The purpose of the fuel/air screw is to fine tune the adjustment of the pilot jet circuit. This circuit most affects starting your bike as well as throttle response and power from 0-ΒΌ throttle inputs.
What makes a carburetor on a dirt bike get dirty?
A carburetor gets dirty because it sits for a period of time. If fuel is left sitting in the carb then it will deteriorate and start to gum up after a while. This is especially true with cheap regular pump gas with high amounts of ethanol.
