I installed a DG pipe and silencer on my 88 KDX. I have a vibration in the pipe that I cant get rid of. It happens about 1/3 throttle. I have replaced springs, silencer grommets, copper gasket. I bought an FMF ring, still vibrates. Anyone had this happen?
how does the pipe help the bike? sorry i dont know the answer, mabye sheck were all the mounts are, and mabye were the pipe meets the silencer could be rattiling against the frame.
