A bit of reality check.
1- is the OP riding with a flashing neon sign saying "SERIAL NUMBER GROUND OFF"? If not, why would the issue even arise in the first place?
2- think about the handling of looted art that turns up in collections or museums. Families trying to establish claims must sue in civil court and prove a number of things; that their forebears originally owned it, haven't sold it, and some evidence to support the claim that it was looted during the war or otherwise stolen. Then they might get an order returning the artwork.
There would be no criminal charges unless a case can be made that the current possessor knew, or must have known, that it was stolen property. That's why there are so few criminal charges filed for simple possession of stolen goods. That's usually reserved for professional dealers in stolen goods, where the shear volume argues against "I thought it was clean".
So even if this bike is so hot that it glows in the dark, there's nearly zero risk of any police interference if you ride it.
