Well, good luck, it is a tricky one. In my case, the bloke I spoke to asked me to send papers marked for his attention! Lucky me!
That said, I have a slight ongoing situation myself that I have avoided contacting DVLA with so far: my XBR was bought new by my Dad, not pre-registered or any malarkey. I am the second owner. The sales receipt is full of mistakes and crossings-out (handwritten), and the V5 has the DEALER as first owner, for ONE DAY, my Dad as second owner, and me as third.
This is annoying, as I'd like the bike to be noted as always being in my family. Not planning to sell it (well, until I'm an old man... I have no kids) but still. Will try to fix it one day, and it doesnt affect daily ownership.
Oh, and those Paris shit bikes? I remember Bike magazine having an article about them ,XT350s IIRC.
