Been nusy so neglected modelling for a while.
Theft
This is becoming more common because it is so easy to sell on stuff.
Set up a throwaway Ebay account, sell on there, so much listed that they could probably get away with it.
I do know that a lot of stolen car parts are sold on there, for example my cars headlamps are popular to steal.
Not everyone would check the sellers credentials like I would.
However keep a look out and you may find your own stolen goods.
Exhausts, been there done that. Expansion pipe on a 2 stroke, a stainless 2 into 1 system on another bike to replace a rusted system.
Fitted a rally system (2 box absorption, large bore, 4-2-1 manifold) to a Sunbeam hatch, I used to pick on boy racers with it.
