How to Clean Carbs Without Removing them from the Bike
If you’re in a pinch and really don’t want to remove the carb, you can try cleaning them while they’re still on the bike by:
- Removing the fuel bowls and throttle caps.
- Removing the pods or airbox.
- Inspecting how dirty the are.
- Spraying carb cleaner spray as best you can.
- Seeing it it made any difference.
Again, if the bike has been sitting for a while, this method is probably not going to be a sufficient cleaning.

- Removing the float bowls.
- Removing and replacing any floats, pins, or jets.
Even if you are able to remove things, the risk of dropping them somewhere where they’ll be hard to find again or get to is a big risk.

- Adjust the pilot screw.
- Adjust the throttle needle clip position.
- Adjust the float tab to change the fuel level.
- Sync the carbs.
