Model: Ducati Monster 821
Part: Battery

Video tutorial

In this guide, we will go through the instructions that will allow us to disassemble and replace the battery of the Ducati Monster 821. First, let's put the motorcycle on the stand and start unscrewing the upper screws of the battery cover and the relay box; then, we unscrew the fastening screws located at the bottom of the battery box in order to remove it, as shown in the video.

At this point, let's disconnect both battery terminals (positive and negative), and then replace it with the new original one (with the same amperage); all that's left is to reassemble everything!

Resetting the Kymco Downtown 300 ECU

If you experience irregular power delivery and idle levels leading to stalling, try resetting the ECU. Turn the ignition key to position one, wait ten seconds, and rotate the right throttle knob to full throttle. Keep it turned for ten seconds and then return it to the resting position. After a few seconds, you will see the "engine malfunction" light briefly flash on the rev counter. Turn off the instruments and start the engine; take it for a test ride to ensure everything is functioning correctly.
