I got this post from this blog. This is probably some corollary to Murphy's Law:
Royal Enfield motorcycles delight in making you look like a fool in front of friends, loved ones, and, especially, attractive members of the opposite sex. How does an inanimate object know that, instead of merely trying to go someplace, you are trying to show off your ability to kick start a mighty beast into life?
I don't know. But my Royal Enfield Bullet knows. To foil me it has moved its own kill switch into the "off" position, and developed instantaneous fuel starvation or flooding.
The fortunate thing is that when the friend, loved one or attractive person gets bored and wanders off, the Royal Enfield will cheerfully return to full operational duty. It's not disloyal; it just wants to keep you humble.
