First, warm up the engine for a few minutes and start unscrewing the fixing screws located on the metal panel under the engine to remove it. Use a socket spanner to unscrew and remove the oil drain bolt, allowing the oil to drain into a container for about ten minutes. At this point, unscrew the filler cap to top up with the correct viscosity oil (as indicated in the motorcycle's user and maintenance manual)!
