To me it sounds like an exhaust header clamp is loose or something similar. That would drive me nuts. 😁👍 _________________ Bit of advice. Buy a good bed and a good pair of shoes, because if you aren't in one you'll be in the other. |

Can’t you move around the bike and listen from what area it’s coming from in particular?
I’ve had similar issues with cars. It drives ya. Last one for me was a squeal on the Twincam . It disappeared when I dipped the clutch so thinking it was the thrust bearing. After much searching it turned out to be aux fan belt slipping under load. At least it was an easy fix and I didn’t get as far as dropping the gearbox  _________________ AKA Bald headed b'stard |

Have you tried - with the motor off - tapping the exhaust gently with wood or rubber mallet. I was thinking this might show you what area the rattle is ( if this method produces the sound). _________________ Well I'll be ..... |

I agree with Stig - I think you have something in your exhaust system - possible swarf, welding dross, escaped washer or captive piece. I think whatever it is when you rev the bike the increased pressure is pushing on the loose piece or forcing it into a corner or trapping area until the pressure drops and allows whatever it is to rattle again. I am assuming you have checked all exup components if you have one. This is interesting please tell us what you find. _________________ Well I'll be ..... |
