How do I know if my motorcycle engine has a carburetor problem?
Here are four telltale signs that your carburetor needs attention.
- It just won’t start. If your engine turns over or cranks, but doesn’t start, it could be due to a dirty carburetor.
- It’s running lean. An engine “runs lean” when the balance of fuel and air gets thrown off.
- It’s running rich.
- It’s flooded.
What does a carb vent tube do on a dirt bike?
These tubes just vent the float bowls to atmosphere, so gas can move, and provide an exit for overflow therefrom. Nothing very special about them; they’re just like what you find on most dirt bikes. Hell, the Bings on airheads just have a hole.
Why do you need a carb vent hose?
The carb vent hoses are necessary I think cause they let the float bowl air pressure stay at atmospheric level rather than at the partial vacuum levels inside the air box. This helps the bowls fill up and also probably affects how much gas is drawn up through the jets.
Why is gas coming out of my CARB on my dirt bike?
This float is connected to a plunger which prevents additional fuel from entering the float bowl. If for some reason this plunger is not allowed to seat in the float valve then gas will continue to come into the carb, overflowing the float bowl and running out the overflow.
Where does the CARB vent go on an adventure rider?
My box-stock* early model has clear carb-vent tubes that run out and down. The left side one goes right down next to the clutch slave cyl. The right side goes…uh…down the right side. These tubes just vent the float bowls to atmosphere, so gas can move, and provide an exit for overflow therefrom.
Where is the CARB vent tube on a bike?
Where the tube passes through the bottom of the air box I used a 90 degree fitting that was left over from the canister plumbing. Then I used a piece of 5/16″ automotive fuel line, that seems to be kink resistant, and ran it to the left side of the bike then down the side near the clutch hose.

Why does my carb vent tube not work?
Some riders have reported that under certain conditions, (high speed following a semi ) turbulant air can upset the jetting. Our theory is that a increase in pressure around the vent tube can upset the fuel mixture.Has anyone else has anyone experienced this, and can comment.
