Well; as the manual says; should you need to charge the battery; Contact a Yamaha dealer, smooth...

Maybe I should be graceful I can fuel it myself...

Since I plan to use my bike as a job-commuter the whole Winter (here in Stockholm Sweden that means below freezing point), and also generally; I would like to be able to charge the battery myself;

I plan to connect wires to the battery and have them ending under the saddle or similar easy accessable Place, for charging and (hopefully never necessary) jump-starting (i.e. Cable of 10mm2).

Anyone know how "tricky" it is to remove the tank to access the battery? - tricky/sensitive connections for the fuel - hose and level sensor.

You should wish Yamaha had made this kind of "feature" original whith the bike.
