I have a Bianchi Snark Eagle Deluxe with A Minarelli V1 Engine on it! When i get going really good, especially when going downhill, it makes this very loud vibration noise, almost like an empty soda can is sitting on it. It sounds like its coming from inside the engine it self but I'm not sure. Maybe the chain is loose or needs to be lubed up more. Anyone have any ideas?
Bump
check if your gas tank is secure super tight. mine makes a high pitch rattle at high speeds.
loose fender(s)?
I checked everything, even the chain, it definitely sounds like its coming from the motor. I feel like i might have to change the oil, or something needs to be replaced internally.
Check any plastic guards or covers, or anything plastic. If its missing screws or cracked, it will sound like a mess.
^ old thread! look at the date!
I bet he never figured it out, though.
