Hi all, I just bought a CB a week ago and I love it. However, two things cropped up today that I needed some help with, I don't know too much about motorcycles apart from youtube and searching other forums. Honestly my mind might just be playing tricks on me but it'd be great to hear from people that actually own the bike.
1) There is a strange buzzing sound coming from under the fuel tank when I turn the key to the on position. I hear the fuel pump turn on but then this buzz that seemed to be coming from the MAF/MAP sensor (not sure) connected to the airbox. I unplugged it and the buzz was still there so not sure where it's coming from. Maybe a servo motor or the solenoid? Or another sensor that I'm missing?
2) I let a buddy take the bike for a spin and when he brought it back, the idle seemed like it took longer to go back after revving it in neutral, like there was a vacuum leak or something. Posted a vid on youtube for someone to compare.

3) Like jodyz post, I too am hearing something like a rattle/tinging from the front part of the engine near the headers. May have just not noticed it before my buddy drove it but still worries me.
Thanks for any help y'all can give me. I hope I'm just being a hypochondriac.
