2022 RX3 Mystery rattle 6000rpm-8000RPM Help!!!

Ten85 · 07-27-2023, 05:13 PM

Good afternoon everyone. First time posting and using a forum. Bear with me. I bought a 2022 CSC RX3. I have produced a rattle vibration and i cannot put my finger on, it might have always been there cause i did not notice it until after 500 miles when i starting brining the RPMS up. I have absolutely checked everything i can think of. Around 6k-8k i get loud rattle where i am bout to wear ear plugs. I checked all engine mounts, engine guards, skid plate every bolt i can see. I pulled the exhaust just to make sure they installed an exhaust gasket. It was there but i still replaced it anyways. Could not find my stethoscope so used a screw driver. Engine feels smooth, the most noise/vibration i can find it right on the exhaust, but still not sure. i pulled off the skid plate and heat shield and the noise was still there. I took it to a local motorcycle shop to make sure it was not engine noise. They said the engine sounded fine, but i cannot find this rattle it is driving me nuts.

Rattle is there in Neutral, its there with clutch lever pulled in, its there moving or not. Has anyone had a similar issue.

Thank you for your time.

My guess is to check the valve lash...might be loose?

Valves are good. That what i thought maybe. First adjusted them to .08 mm went back and put them at .06 mm and all is good there.

Found out what it was. Engine was bad and blew up 400 miles after this post. Sounds like a crank or rod. CSC is sending me a new engine. Fantastic customer service. lets hope this engine is not bad..

I was gonna suggest plastics, 'cause mine rattled pretty loud at certain RPM's until I found that forward bolt and cinched it down.
