As above, this has being going on for a while now and it's becoming irritating.
At completely random intervals the bike will appear to have a flat battery when I go to start it, and I just get a buzzing sound.
Thing is, once I get it started via jump leads it won't do it again for ages.
I did have an issue with my side stand switch but I've bypassed that now by connecting the wires, not ideal I know but the switch is in a terrible place to get to so it'll do for now.
When this has happened before I've ridden the bike to work and put the battery on charge and it shows as full in less than half hour so I don't believe it is a dud battery problem. Also once I do get it started it will start absolutely fine on the button for weeks or even months before it does it again.
I last used the bike on Friday, and it wasn't raining so I don't think it's a water issue either.
All battery connections are good and tight, and the battery is maybe 3 years old, but as I've said I don't think it's that otherwise it would be happening much more frequently.
Other than this, everything else is working fine.
Any ideas welcomed, I'm a bit stumped at the moment?
