Hi guys, For anyone who is interested, I found a store in the UK that machine specialist tools such as castle lock nut sockets for your swing arm for pretty good prices. If you go to Ebay UK and search for "castle lock nut socket" you'll find it. Turbosuzukis is the name of the guys Ebay store. He has a good range. As an example he had a copy of the Honda MC28 swingarm offset castle lock nut tool, so you can lock the torque the castle nut correctly, in stock. It was less than half the price of the Honda tool. Seems like he has most castle nut socket sizes for most bikes. Cheers Jim
Here is an example of some of his work. Looks like good quality. CNC machined. I'll let you know what they are like when I get back home.
