Hi everyone, I'm a newbie to the dirtbike world and have recently purchased a 1990 KDX200. I love the bike but I have noticed that in 3rd and 4th gear there is a ringing noise when I am hard on the throttle. It is a metallic ringing sound that can also be heard by other people as I ride by. If I let off the throttle the noise disappears and if I roll on the throttle it comes back. Any thoughts on what this might be? Is it the power valve?
I have one more question. My bike has about 2300 miles on it and I believe it still has the original piston. Since I don't know a lot of history about the bike would you recommend that I replace the piston? I have searched the forum and it seems like the KDX200 is pretty bullet proof but I don't want to damage anything. Particularly since I'm having so much fun.
Many thanks,
Stephen
