The answer can be found on page 2-10 of the factory Suzuki service manual for your bike...

FWIW: the D8EA is a smaller diameter plug than the more common D8ES. Rule of thumb is all the 2V/cylinder GS bikes, excepting for the 650, use the D8ES, whereas the 4V/cylinder bikes used the smaller D8EA plugs.
R plugs, which stands for resistor, are not ideal since the plug cap already has a resistor. Generally speaking they won't hurt anything though.Last edited by Nessism; 06-19-2021, 03:38 PM.Ed
