Hi people,

I'm doing a big trip and this is starting to worry me. Every now and then my bike is really hard to start. When I start the ignition, it just tries to start, but doesn't. Slowly, after 10 long tries, it eventually and slowly, starts. Sometimes I need to go downhill to bumpstart it. The battery is not flat, but it doesn't take much more tries.... Normally it starts in 1 go even after not being used for weeks.
So, what could be wrong? The battery is charging, I drive a lot because I'm travelling a few 100km a day. The battery is 5years old, but normally starts in 1 go. Except... Sometimes (once every 10 days or so) not.
I'm getting a new battery anyway now, but will this be the solution? I'm travelling in the middle of nowhere so I must be sure.
Last service: 3000km ago. New oil, spark plug, etc.
