With fuel rarer than long lasting drop links I'm surprised there hasn't yet seemingly been a run on siphoning fuel. Being of a nervous disposition I thought I'd investigate getting a locking fuel filler cap but the only one I can find so far is
this hardly a snip at £26, and I would have thought could be opened with any handy paper clip. There are others listed on eBay saying they will fit our motors but when you click on it they say they don't.
So there's a tidy fortune for anyone who can produce a good cap.
