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.
Where are the CARB drain and breather hoses?
The hoses on the bottom of the carbs are fuel overflow hoses. If your carb bowls get too full, then gas will run out the bottom drain, and through the hoses. So those hoses need to run to where the gas won’t hurt anything. Usually, behind the engine, under the swing arm (where you battery vent hose goes).
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.
Where is the vent hose for a crankcase breather?
Another option for the crankcase breather venting is to find a rubber L shape connector that fits snugly onto the crankcase breather vent pipe and then run a thin-wall hose from the connector to exit underneath the bike. The new crankcase breather vent hose may be routed adjacent to the bundled floatbowl overflow tubes.

Is there drain in bottom of CARB vent?
We placed no filters on the lines as they do not breath (constantly suck) and as far as gas spilling in bottom of box we he did not see this as anymore of a problem than the stock vent lines on 03 spilling directly out bottom of box. There is drain in box if it became excessive and it does drain directly onto exhaust.
How are carb vent lines sensitive to gas?
These carb are very sensitive to venting. We placed no filters on the lines as they do not breath (constantly suck) and as far as gas spilling in bottom of box we he did not see this as anymore of a problem than the stock vent lines on 03 spilling directly out bottom of box.

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.
