Well I took off the other day and the bike just stalled out on me pulled over and she wouldnt start. Ran home came back about half an hour later and the bike starts up on reserve tank so I figured my dumb ass ran out of gas even though I was pretty sure I had plenty. Pull in to the gas station. The bike only takes a gallon of gas. Think oh well it wasnt out of gas. So I turn it on and it shuts off right away ...put it on reserve and it is fine. So half way home turn it to regular tank works fine and then the next time I ride it is fine. Do you think this is vapor Lock or Dirt or what should I check out. Just want to fix whatevers up. Dont want to screw around when the real nice days get here.....
