Just bought my bike a while back and kept the manual at home to read when I could. Not a good idea when your out riding and have a problem and need it! Went to work. Turned key to park instead of off position. (Did I mention I am brain dead at times). Worked for 3 1/2 hours then went to leave and bike is dead!! No battery life at all. Had not read the part in the manual about how to remove the seat. Took off bolt in back of seat but couldn't get it off. Had to borrow a car to go home and get manual (which was a big help -
take out bolt remove seat 
Had to do a search on this forum. Found just what I needed
This site is awesome! Finally got it jumped and running. It was rough but I had to go for along ride to charge the battery back up
So lesson learned - Keep manual in bike so you have it when you need it but read up on basics you need to know ASAP. It's easier that way!! OH also make sure you turn key to front not back of bike when shutting it off!!
