Well I've just discovered the one for the 400 is different. Different part number anyhoo. May be the same tool.http://www.gearhead.com/honda-99004-18002.html#/s/HOM//99004-18002/1
...that looks just the job Steve, but what's the 'waisting' for towards the plug end?I too have 'Honda' plug spanners in my 400/750 'kits (or so I thought upto now).... cheapish alloy box spanners.
