Recently I was working on a a hypermotard using a nut tool to turn the motor over via the jack shaft. I'd brought the tool from the US ages ago, it cam with 2 nut tools and a pin spanner. One of them is good, the other the pins that engage the nut bent the tangs just turning the motor over. (Plugs out) Here's a solution, just taking it to be tig'd today. I just cut out the tangs and have used keyway stock which is a perfect fit. My bevel countershaft lock nut tool uses keyway stock and is still going strong after 30 years.
