Shenandoah Circuit Gearing

Can anyone give me a gear ratio for the Yamaha Sportsman class (lite and medium) that will get me in the ballpark for the Shenandoah track at Summit Point.
Thanks

OK Larry, since nobody replied, for a Leopard on Summit Main, we run a 16/78. For Shenandoah we run a 16/85. SO, add about 6 or 7 teeth to the axle gear would be a good guess? I would hope one of our Yamaha guys would reply! Come on guys!
You should have mentioned that last Thursday on the GT5 race! Confused

Larry --

I would consider adding 3-5 teeth more than that, given that our handling generally isn't as good as theirs...not that I've ever run especially well there, 14/80 might be worth considering as a starting point...

Larry what size tires you running as well. Scott has given you a good starting point. May need to go up or down from there. Depending on motor and tires size.
