I had one of these kits for my Firestorm which somebody kindly put me onto, it's a very simple tool which IMO works very well and doesn't cost an arm and a leg. The one advertised here is for a Moto Guzzi, but I think it will be the same one for the Storm but probably best email him and ask before you purchase
I haven't really considered any other make/type ,but will have a look at your suggestion. Used the Davida s years ago sooo thought I'd try them.
Thanks again
