Karboy bushing question/problem
 

I put the KB bushing on tonite and somehow I hear a faint whistle while accelerating or cruising in gear. But it's quiet if I just give it a bit of gas to keep it going at the same speed. What did I screw up?

More than likely, nothing.

Mine does the same thing. It sounds like a whistle, but I think it's more of a vibrating, hum-rattle. Due to the hardness of the bushing, it's the trade-off of having a better feel.
