Re: winter blues
Here in a little bit I'm going to swap out my NGK B6HS spark plug for a B5HS.
(From Sick Bike Parts. I know I could'a bought it locally. But they're good guys and deserve whatever business I can send their way.)
I don't know whether to expect any noticeable difference in performance or not.
But stuff like this is a good antidote to the winter blues.
