Can anyone help me I have a 99 zx6r with 5800 miles on her that has an awful rattle on the right side of the motor. I just bought her and heard nothing until about two weeks of riding. I was only hearing it after a rev came down or if I keep the throttle open lightly at like 3000 rpm constently. It would come and go but It seems to be happening more often. I looked around in this forum and was amazed at how much info you guys give about these great machines and I saw some posts about the cam chain tensioner. Have I damaged the bike by riding it a few times with the noise? It took me awhile to figure out what it was and I probably would'nt without your help. I also read that this is a common problem with 98 to 2001 ninjas. Does anyone know if this will have to be replaced all the time I saw a post that said this was a faulty part. I went to the dealer where I bought the bike and the guy said its normal to hear these noises and if I had to replace this it would have to be taken apart to see what was faulty in the cam chain tensioner. I thought this was one complete bolt in part. I don't know much about motorcycle motors but the noises I'm hearing don't sound normal. I'm sorry for the long post but I really need some advice with this. Thanks in advance!!!
