Seriously. I have no idea what could be causing that. Can you duplicate it when not on the bike and try pinpointing what area it's coming from?
When I die, no funeral. Funeral services are an incredible waste of time/money and no one ever wants to go to them. If those closest to me wish to get together and have a good time laughing and remembering our times together instead of sobbing over my awkwardly stiff body lying in a box, that's cool with me.
