So...the old clutch was a little bit grabby on the Triumph. No problem, thought I, oil it. As I'm sure you're aware, it is quite difficult to really get the oil down a cable, so I sought advice from my classic-bike owning neighbour.
He told of a contraption that attaches to the top of the cable and allows you so inject oil thus allowing decent oiling. He told me they only cost about a tenner "look it up on the internet, it's called a Lube Tube or something like that". So I Googled

Perhaps I shouldn't trust these older folk anymore...
