Yesterday I'm commuting home on the Monster when I notice it sounds... funny. Like more chattery than usual. So I try giving it some gas and the noise goes away a bit. Back off the gas and it's there again. This continues for a while and I'm starting to get pissed off. I curse every Italian I can think of for building this piece of garbage and roll through what could be wrong with it as I pull up to a stop light.
Then I notice a guy on a Harley pulling up behind me and his bike sounds like smashed ass. He was behind me the entire time - farther behind when I was gassing it.
Oops.
Karmic justice - I got a shard of metal in my rear tire about 1/4 mile from home.
