Yamaha diversion 900 battery removal Can't seem to access the battery without removing side panel which won't come off Is there an easy way to charge the battery without removing it?

If the side panel is completely unmovable you can remove the petrol tank trace the main positive cable and using an adapter (8mm male spade connector) connect the positive charging cable into there. The negative charging cable can be connected to the frame or engine. you should be able to reach the negative cable connection point on the rear of the engine. alternatively fix the side panel and replace the fasteners and chase the threads so its easier to get off next time.
