I saw the action also, the cab-cam in that tripple axel big rig was sweet, that guy was haulin' the bacon!! Guy in the Bronco was flyin. I watched the bikes but the trucks were just awesome.
This really sucks, I was planning to watch the event, as I do every year, but I did not know it was coming on. Is there going to be a re-broadcast? When did it originally air?
I was thinking for the dirt bikes it would be effective to add a power jet circuit (or two) to the carb for lower elevations, which could be switched off as altitude increases. Those dirt bikes sound pretty sick towards the top. Maybe oxygen injection?
