Maybe I got lucky for the moment and have the lucky R value sparkplug in my 2017 GS whatever the heck that is. I might just suggest although I am sure you have already made sure all the connectors are well pushed in, as they are quite hard to push to the end.
Yeah, or maybe we just got unlucky! All the leads are connected tightly (with the metal screw collars, it’s difficult for them not to be).
I’ve just checked my plugs as the bike was serviced when I bought it last month and it already has resistor plugs. Now waiting for another response. Disappointed.
