Title: Rattle At 2K RPM
Post by: lad on April 11, 2021, 07:55:53 AM: There’s a mad rattle when i’m at 2K RPM that sounds like a bag of empty drinks cans, coming from this genera area...

Is this a common thing? I remember someone mentioned a vibration where you feel your right foot to numb.

Maybe I forgot to tighten something?

I guess someone could have had it apart and not properly spaced the swingarm bearings. Pretty unlikely though.

Is it a tinny rattle or more of a clunk,
Wayne is probably right, exhaust.

Guzzi's are happiest above about 3500 rpm. If this is happening at a standstill while free revving the engine, clutch lever pulled to bar you are probably hearing the clutch plates rattle, lever out could be slop between clutch plates and input hub on transmission or play in transmission, dogs, etc. on shafts.
