At my last service my mechanic, (now my ex-mechanic), adjusted the chain, TICK, but didn't tighten up the axle adjuster, CROSS, with the consequence that it came undone and fell off! I put out a whinge about the situation in general on the local riders' forum here in Wollongong. One of the members PMd me, "I've got a crashed 250 Hornet in the shed, I'm sure it has the same part, come and get it if you want." What a champion, eh???
