Hello, I would appreciate some info on the following - When running NGK B9HCS plugs in my 1972 H2, what is the best gap setting for these plugs when running 91 Octane unleaded petrol in the bike?

Thanks, I checked them yesterday and they are set at 0.6mm so I'll try 1mm and hopefully that will improve things
