Glad you got it sorted, you don't really want that box coming off when you're bombing it down a motorway!

As a side note my lock started getting very stiff recently (I've had it 10 months now) and getting the key out was getting troublesome. Visited my dealer who said they normally squirt bike locks with a bit of chain lube which does the trick so recommended that. Gave it a go and hey presto to lock works like new again. Aparently the mechanic I spoke to used to do this every week with his own bike when it was being used in all weather so will have to see how long the effect lasts for.
