Here is a nice TV commercial. It's from Harley-Davidson Europe, and in this "commercial" they have a Harley-Davidson motorcycle play a Christmas song (Silent Night) just by running the engine up & down.
I just wonder how much of this is true, or was it faked..... and in the end, when the rider has left the bike, you see the motorcycle on its own, I see no oil puddle... (sorry, couldn't resist).
You can hear what the song is, so if it's real, then it's well done.
Anyway, it's a nice one. Enjoy
