Thanks for the responses. There is no doubt in my mind that the leak was a direct result of the service whilst checking the valve clearances. I had a more reasonable conversation with the mechanic who whilst not admitting it was his mistake apologised for the inconvenience caused and his boss's reaction. He said that maybe he could have picked it up whilst servicing if he'd run the bike for longer or examined the part more carefully or maybe it happened whilst removing/installing but there is no way to be sure. I wasn't looking to make an issue of it so long as it was resolved and hoped maybe for some discount on the service for the inconvenience. But right from the start when reporting the problem they were on the defensive and the owner just wouldn't even admit the slightest hint of a link between the service and the leak and then just blew his top. He even complained on picking the bike up that it probably would have been okay to ride back to them on Friday - even with oil splattered on a NEW back tyre! Anyway, I may still report it to Suzuki in case this branch has a track record of treating customers like this but like you've both advised I will be placing my business elsewhere and have already had a couple of recommendations for an independent mechanic so will try him next time.
