Use it every day and it's ok. If it sits for a couple of days drips gasoline after started. I have watched it after the key is on and the fuel pump pressurizes. No spillage. Once engine started then the drippage begins. I ride it 11 miles to work. I let it idle at dismount and no gas evident. End of 11 hour day, I start it, no matter what the temp, 90 or 45, (you get the idea) no spillage. Let it sit a couple of days then problem is back. Gasoline puddling under bike after engine start up. What's going on?
