[QUOTE="Krusty"] When I got the Fantic MOT'd a few weeks ago I forgot to take the V5, so they read the number off the frame to stick in the 'puter instead. Well it turns out the frame number doesn't match the one on the V5, so the DVLA are now 'investigating' it. I don't know if the V5 number got screwed at some point during an address change, but I do know there's nothing hookey with the bike, having owned it for 22 years (& my dad owned it for 4 years before me). The DVLA are now saying I'll probably have to take the bike in to be inspected. Never having done that before, what can I expect to happen? They won't tell me what the results may be. If there's any chance at all they may seize it, I need to get the (somewhat valuable) engine out first & pretend it's blown up or something.[/QUOTE] I had it happen once - misplaced digit on a V5 (surprisingly common). Bloke just rocked up, looked at it, said: "That's OK," and that was that.
