So i drove the bike to work last night and when i got home this morning i ledt it outside in driveway for first time. When i woke up it was in the 90 degrees. I walked up to bike and it was leaking gas from under gas cap ring. I popped gas cap could hear pressure release. Closed gas cap amd 10 minutes later opened it and gas is back filling out edge of gas tank cap. What is issue here? Easy fix or just a bad tank?
