I think that you probably made the right choice for your chain. Since you are likely to encounter mud during your rides(what? rain in Washington?), you will get a better bang for your buck with an O-ring chain. When you run two O-rings on the BW, the drag is quite noticeable. If you were looking for maximum horsepower (at the dragstrip, Supercross or the Salt Flats) the cheaper standard chains are the way to go.
Cliff is going to race the "Mamma Didn't Raise No Fool Class" at EnduroX. Just like the race we ran in Alaska, Cliff will be the man behind the camera, sucking down a beer as the fools thrash and flail around the track.
(I'm going to try to get him to run the 350 around the track during one of the practices though. Just don't tell him I said that)
