NGK plug, yup! Br6es. I have a pair of 8’s (new) that came with the bike But the six was doing fine. Nice and brown just the way I like it. I’m afraid to stick the eight in there, afraid it might be too hot.

The 8 is a colder plug.
NGK gets colder as numbers go up.
The 8 is the correct plug for the bike.
You don't need the resister(r) type plug. There is already a suppression resister in the plug wire.
B8ES is fine.

I'll give one a try. maybe I'll get the correct jetting too . I can't imagine why someone would stick a 160 in there
