Can anybody tell me what gearing the Senior and Master guys were running at the Pan American Challenge at The Track last week in Colorado?

Thanx in advance

Hi Angel,

I know that is what we usually use but was interested if these guys and gals were able to use a 78 or 79 tooth seeing they were killing the rotax lap times. I am assuming the track rubbered in pretty heavy and that is why we were seeing those times.

12/75

Are you sure on this one Mike?

How are they pulling out of the 160 deg. turn in the infield?

Rodney,

So it is confirmed that 12/75 is what the senior guys and gals were running?

If so WOW that is impressive. I've tried a 78 in the past but ended back at 80. I am humbled.
