  • All you have to do it is removing air box or pod filters; do not worry as they can be easily reinstalled.
  • Once it is removed, you get easy access to the butterfly valves (back of the carburetor).
  • Now remove the carburetor bowl at the bottom which is attached with screws in the centre of the carburetor.
  • Turn off the petcock to avoid gasoline leakage.
  • Once everything is exposed, spray carb cleaner after every few minutes to loosen up the deposits.
  • If it still seems like it is not clear enough to remove the float (a rocket-shaped part on the top). You can check the float’s functionality by submerging it in water to check if it floats; if not, get a new one.
  • Getting the float off will reveal the jets. They get clogged pretty fast, so clean them thoroughly.
  • After this even spray the carb cleaner over the carburetor and clean it up.
  • Put back all the parts and voila!
