So i just finished the install of a -1 on my 750. Now when i get up to about 55mph i start to hear a whining sound, and also on decel it sounds like an airplane powering down. Also when i'm at about 5k and try to go full throttle it feels like it slips and there is no power, same when I hit about 10k. Any one have an answer as to what might be wrong or what I need to do to fix it? PLEASE PLEASE PLEASE help. :bowdown:
