[QUOTE="Braap38, post: 232714, member: 6981"] Hello, new to this forum. Was hoping someone could help me with identifying this rattle/noise. The bike is a 2020 CRF 250f. We just bought this bike used. I do not know how many hours on it. It sounds great at an idle and low revving. The noise comes on when you wind it up. Makes the sound in [URL='https://www.thumpertalk.com/link/click/4497/']gear[/URL], in neutral, & it doesn't matter if the [URL='https://www.thumpertalk.com/link/click/5119/']clutch[/URL] is pulled in or not, still makes the noise. I have checked every single bolt. Motor mount. Everything external on the bike, nothing is lose or broken. Any suggestions would be helpful. We really do not have a good bike shop where we live. Tearing into it is not a problem for me, but would like a suggestion on where to start. In the video link, the first time I rev it it is normal. No noise. The second & third time you will definitely hear it. It seems to be at an exact RMP range. If I rev past the noise, it seems to go away. It also seems to be much louder under a load when I am riding it. Thank you. [/QUOTE]
