Dahon Folding Bike

I recently purchased a second hand Dahon Speed Pro TT and have since noticed that when changing gear, the chain flips/whips slightly and in doing so catches the chainstay. It seems to happen when the chain is between the two sprockets and is not under load. As a result the paintwork has now become damaged.

When the gear is engaged there appears to be enough tension on the chain and all the components on the bike seem to be original, as supplied when new.

Has anyone experienced similar or have any suggestions as to how to stop this happening?

    Not had anything like that on my Jetstream (had it for 2 1/2 years)- chain drops, yes, but not 'chain whips'. I'd say take it to a Dahon dealer (or at least a decent LBS) and get it checked out.
