Today I stopped at the supermarket after a very nice 2 hour ride and left the key in the "ON" position for about 4 minutes and when I tried to start the bike on IT WAS DEAD! had to start it going down hill using the clutch... after this I was albe to turn it back on w/o problems! Are this my battery's last days? if so, which battery should a I get to replace it and where do you guys think could I find a good price one? Thanks again!
