I was forced into a full emergency stop and couldn’t/didn’t de-clutch. As the engine died I heard a metallic “pink” that sounded much like a couple of wrenches tapped together once. Since then there’s a persistent rattle emanating from the area of the transmission. As the transmission warms up to operating temperature the rattle subsides to a point where it’s barely audible. While rattling away cold at idle, when the clutch is disengaged the rattle disappears and often when released the rattle subsides somewhat. I’m aware that a worn transmission can sound a bit loose and that carburetor imbalance can artificially induce a rattle at idle however this particular box has 30k on it, is original to the motorcycle and was quiet when installed and run for nearly 5000 miles. It’s not carburetor and it’s not clutch as the idle is spot on and the clutch is light, smooth and positive and the adjustment is fine. There’s no metal in the gear oil like shiny stuff on the magnet or gold sparkles suspended in the oil. I’ve switched to a higher quality gear lube but - no joy.
