Thanks to everyone for the welcome
So far I can confirm that the sprocket has been changed, it has the bolt on chassis strengthening, the empire steering kit and cooling kit. Now need to add hose/line clamps and exhaust bobbins to the check list.
Having taken it for a short test drive on a cold day, I was a bit surprised at how much noise it can generate on longer drive on a hot day once I had bought it and needed to drive it home - hence me wanting to understand the NVH kit and compensator design level. Ear plugs and crash helmet may be cheaper though.
