Thanks for the info, guys. My bike isn't even broken in yet. It's been too cold, wet and nasty here in northern Illinois to ride it. All I've done so far is idle up and down the street a little bit and in my yard and last Saturday I fouled the original plug already doing that. I need to buy a couple of spares and that's why I asked the question. I figured BR8ES plugs would work fine, but wasn't sure. Anyone ever use anything besides NGK's?
