These thieving gits know that the little bits like locks and rubbers are expensive for what they are and sometime difficult to get hold of.
Some years ago,a mate had a few of his fairing screws taken at Donington.He did,nt notice untill he got up to speed and the fairing started flapping.The screws were a stupid price and the plastic washers that went behind them,even more expensive.We bodged it together with some galvanised roofing bolts.
