its perfectly normal. some of it might just be cuz its new and everythings just getting to be broke in. also the 450 motors are a high performance motor and make those kinds of noise because of how tight and packed everything is inside the motor. i know mine did it first day and still does it to this day but hasn't hurt anything. i wouldnt worry about it but i would get your valves adjusted again soon cuz of it being new and part of the noise could also be from that.
