I would like to poll you guys who race motorcross on high and low compression motors. I have a few questions:

Do you race Motorcross?
What class?
Do you run a high compression motor with race fuel or a pump gas motor?
In your class, approximately what percentage of riders would you say run high compression motors with race fuel?
Do you notice a significant advantage from a high compression motor on race fuel?
