Just wondering my 450 as a chirping noise in the air box put the stethoscope to it and it sounds like it is in the carb. listened to my friends and it has no noise. any body else have this or know what it is bike runs fine. just for the guy that is interested the pipe is modified stock, lide off, cam mode ,165 main, 5 lbs. air in tires will do 76.5mph on gps. pavement thanks Richard.

 

its been my experience that all FCR's make that noise, dont really know why but Ive owned 3 machines with FCR's and they all did it!

 

thanks for the info makes me feal a littel better but the guy i ride with his dont make the noise.

 

I have heard it on some and not on another. Like scwendi says, they chirp. I have only heard one that does not. I think it sounds cool!
