Although it's cheesy to ask, many of us are curious about what you might have paid (like me.)

Also, a "rattle" doesn't sound quite right. Yes, there is some typical engine noise and the thing vibrates a lot at speed, but I'm not sure I'd say mine rattles. Might just ba a matter of perception though. I'd take a look for loose parts - perhaps the trim, or exhaust? Also, A bike ridden that few miles may run a little rough until you get a couple of tanks of gas through it.
