I have searched and searched the forums and cannot find a post that matches what I am hearing from my DRZ. My apologies in advance if I have somehow missed it. 2005 DRZ400SM 4500 miles Yosh - 3x3 - JD kit At nearly all rpm ranges above idle (at idle I dont hear it) I have this bell ringing sound coming from the right side of the motor. I have checked every piece and part that I can think of and everything is tight. Could this be internal? Has anyone ever had this happen? It sounds like those little bells that you see hanging off the frame on a Harley. :moon: ....Help!!!!
