Thanks, that's a lot of help, I've wondered about fitting it for front sprocket oiling, less chance of oiling the tyre or like you say knocking it when "cleaning"! Drilling and tapping the swingarm and making a bracket was going to be it but would need to take back wheel off to get the drill and tapper in, don't fancy extra holes in a stressed member either. I'll have a butchers at the front job cheers, happy riding
