Ok, took the bike in for service a few thousand miles ago and part of that was changing the oil. I went to change the oil yesterday and cannot remove the filter, seems they've wrenched it on quite hard. Last time this happened I broke the wrench (metal strap around the filter ripped in two). This time I went back to the mechanic and requested to borrow whatever tool he used with a promise to return it asap. Well he showed me the special tool to remove the filter (beefed up metal cap that fits on a socket wrench) but wouldn't let me borrow it. Not happy right now as the bike is sitting with no oil and can't get the filter off to complete the oil change. Thinking about following the book and wait till next oil change to deal with this but that doesn't help if I forget to take it back to the mechanic to loosen it at which time I'm sure he'll charge for an hour of work, just because.
