Engine noise
hughes:
After I installed a pipe guard the noise is almost gone. I guess the extra weight on the pipe is keeping it from vibrating. I am just going to use it. I have new springs and 0-ring sealed with silicone.

OLD THREAD ALERT!!!
I have this noise too. Very loud at idle. I can hear it in the house. I have the bash plate off right now, and will put it back on later and retry.
Top end just done, all new o rings, piston, re plate, reed block (v2). Seems like this may be a common thing on these bikes?
martinfan30:
The noise seemed to change a little with the bash plate on, but still loud. It goes with RPM up to about 2000, then you cant hear it.

Every time that noise happens in my bike ( 04KX500 ) the exhaust mounts are the culprit and I find one or more is broken. I keep several in my tool box. Another noise I have heard is from the kicker hitting the Gnarley pipe.
Hope you find the cause of your noise easily.

The mount at the top bend of the pipe is busted. I wired it together, but not sure if its good enough.
