Firecracker?

[Lofty999]

Wondered if anybody else has experienced this.Filled with petrol today in the hot weather,travelled approx 2 miles steadily and lifted off to pass a cyclist.At this point heard a bang/spark noise just like a Chinese cracker from the near side.No further issues but just wondered if anybody else has any idea what it may have beenFull tank,hot weather,warm engine,just a bit concerned,Steve
