Weird Noise (Maybe Paranoid)

1117 Views 3 Replies 4 Participants Last post by  BigDog
I drilled my pips\es out about 2000 miles ago, total of 4900 miles, and it feels like maybe i have lost some power. When i accelerate there seems to be a "knocking" coming from the motor that is not there when idleing or just cruising at a constant speed. I even leaned down to listen to the motor on the interstate and it is purring like a kitten at 80. Could my bike be running lean/rich? If so how do i tell and adjust the carb? If i am just being paranoid and the engineis supposed to be making noise then just shoot me.

Thanks for your help,

Did you loosten anything when you did the drilling? Loos things at the tips of the pipes sound like it's coming from the front of the bike.
