Hey you guys,

I had an awesome track day at Kyalami today!
I had one issue though, can someone help me please?
After lunch I took my key out of my pocket and tried to start the bike.
All I heard was one click and everything died, clocks everything, we fidgeted around under the seat and saw the clock come on once or twice for a split second just to die again, we could not repeat any of the results.
So we jump started the bike with my friends BMW 3 series, let the car run for about twenty minutes and started the bike all fine, but as soon as we take my bike off the cars power she dies after 20 - 30 seconds, so much that when I turn the key, the guages dont even light up???
The battery is less than a month old. What could this be?
