the noise

Dear Neighbor,
Thanks for being generally nice, in a non-committal way. We wanted to move to a place a little less prissy than the very Suburban place we used to live in, so we're trying to just hang with things, and not be, well, prissy.
But.
The motorcycle? The one that you drive? That is Loud? LOUD? LOOOOOUUUUD?
I'd like to ask you to tone it down, but do I really want to start alienating you? Do I want to be a jerk and complain to our landlord? And yet. You have woken my baby up. You have not woken me up, yet, but I'm waiting for it. Mostly, though, I just am incredulous. It's so offensive. It's so loud. It is much, much louder than it needs to be. It is a gunshot that keeps on giving.
Aren't there laws about noise, and mufflers, and such? Do the police not take them seriously? It's clear that you do not take them seriously.
Really, neighbor, I am at a loss.
Peacefully,
Me
